Description

Technical Field

[0001] This disclosure generally relates to a combined cycle power plant system, and more particularly to a hinged baffle assembly (sometimes also called a hinged baffle system) for a heat recovery steam generator (HRSG) of a combined cycle power plant system. Background Technology

[0002] Power systems typically comprise various turbines and / or systems used to generate operating loads and / or power output. Two conventional power systems for generating operating loads include steam turbine systems and combined cycle power plants, which typically comprise one or more gas turbine systems and one or more steam turbine systems. A conventional combined cycle power plant employs one or more gas turbine systems operatively coupled to one or more steam turbine systems. The gas turbine system includes a combustor and compressor coupled to the gas turbine. The gas turbine is often coupled to and drives external components, such as generators, to generate loads or power output. A steam turbine system may include a high-pressure (HP) turbine section operatively coupled to an intermediate-pressure (IP) turbine section, which in turn is coupled to a low-pressure (LP) turbine. Similar to gas turbine systems, gas turbines employ HP, IP, and LP turbines to drive external components (e.g., generators). In a typical combined cycle power plant, exhaust gas from the gas turbine is fed to a heat recovery steam generator (HRSG), which can be used to reheat steam and supply it to various turbines in the steam turbine system for enhanced system and / or power plant efficiency. Downstream of the HRSG, the exhaust gas is released into the atmosphere through the pipe assembly.

[0003] To improve efficiency within certain sections of a combined cycle power plant, baffle systems or components can be used to guide the working fluid of the combined cycle power plant through various sections. For example, an HRSG may include a baffle system to guide or redirect exhaust gas (e.g., working fluid) through the HRSG to interact and / or flow over components of the HRSG responsible for generating and / or heating steam. Conventional baffle systems for HRSGs may include multiple elongated sheets that can be inserted, slidable, and / or secured by a track system positioned at each end of the sheet. For example, each elongated sheet forming a conventional baffle system for an HRSG may mate with and / or slidably engage with a corresponding track system contained within the HRSG. The track system allows the elongated sheet to move along the track system until each elongated sheet is positioned in a desired location for guiding the exhaust gas within the HRSG.

[0004] In conventional baffle systems, each of the extended plates is held in place solely by a track system, and the position of the extended plates can change over time, creating gaps between the plates. Furthermore, or alternatively, gaps can form between the plates due to improper installation of the baffle system within the HRSG. Specifically, installation is often difficult and time-consuming due to the location of the baffle system within the HRSG and / or the limited space surrounding it, frequently leading to improper installation of the plates within the HRSG (e.g., gap formation). Gaps between the plates in conventional baffle systems can cause exhaust gas to leak from the HRSG or from the desired flow path of exhaust gas within the HRSG. This leakage of exhaust gas from the HRSG and / or the desired flow path subsequently reduces the efficiency and / or operating performance of the HRSG, and ultimately reduces the overall efficiency and / or operating performance of the combined cycle power unit.

Detailed Implementation

[0041] As an initial matter, in order to clearly describe the present disclosure, it will be necessary to select certain terms when referring to and describing the relevant machine parts within a combined cycle power system. In doing so, common industry terms will be used and adopted in a manner consistent with their accepted meanings, where possible. Unless otherwise specified, such terms should be given a broad interpretation consistent with the context of this application and the scope of the appended claims. Those skilled in the art will recognize that several different or overlapping terms may generally be used to refer to a particular part. What may be described herein as a single part may be included or referenced in another context as comprising multiple parts. Alternatively, what may be described herein as comprising multiple parts may elsewhere refer to a single part.

[0042] In addition, several descriptive terms may be used frequently throughout this document, and it shall prove helpful to define these terms at the beginning of this section. Unless otherwise specified, these terms and their definitions are as follows. As used herein, “downstream” and “upstream” are terms that describe the direction of flow relative to a fluid, such as the working fluid of a turbine engine, or, for example, the flow of air / fluid through a combustor, or the flow of coolant through one of the components of a turbine. The term “downstream” corresponds to the direction of fluid flow, and the term “upstream” refers to the direction opposite to that flow. Without any other specific designation, the terms “front” and “rear” refer to directions, where “front” refers to the front of the engine or the end of the compressor, and “rear” refers to the rear of the engine or the end of the turbine. It is often necessary to describe parts with their central axis located at different radial positions. The term “radial” refers to movement or position perpendicular to the axis. In such cases, if a first part is located closer to the axis than a second part, this document will specify that the first part is “radially inward” or “inner” than the second part. On the other hand, if the first component is located further from the axis than the second component, this document may specify the first component as being "radially outward" or "outer" from the second component. The term "axial" refers to movement or position parallel to the axis. Finally, the term "circumferential" refers to movement or position about the axis. As will be appreciated, these terms can be applied with respect to the central axis of the turbine.

[0043] As explained above, this disclosure generally relates to combined cycle power systems, and more particularly to hinged baffle assemblies for heat recovery steam generators (HRSGs) in combined cycle power systems.

[0044] The following is for reference Figure 1-12 These and other embodiments are discussed. However, those skilled in the art will readily recognize that the detailed descriptions given herein with reference to these figures are for illustrative purposes only and should not be construed as limiting.

[0045] Figure 1Schematic drawings of system 10 are shown according to various embodiments of this disclosure. As shown, system 10 may include a combined cycle power plant system 12 (hereinafter, "power plant system 12"), which includes a steam turbine (ST) system 18, which, in the illustrated drawing, may include a high-pressure (HP) section 20, an intermediate-pressure (IP) section 22, and a low-pressure (LP) section 24, as known in the art. The HP section 20, IP section 22, and LP section 24 of the ST system 18 may all be coupled to and / or positioned on the shaft 26 and / or configured to rotate the shaft 26 to generate mechanical work and / or to drive additional components of the ST system 18. Figure 1 As shown, the shaft 26 of the ST system 18 may be connected to and / or drive external components, such as a generator 28 configured to generate power and / or produce loads.

[0046] The power unit system 12 may also include a gas turbine (GT) system 30. The GT system 30 may include a compressor 32. The compressor 32 compresses the incoming flow of fluid 34 (e.g., air) as it flows through it. The GT system 30 may also include multi-stage stator guide vanes (not shown) and rotating blades (not shown) positioned within the compressor 32. The stator guide vanes and rotating blades positioned within the compressor 32 may be configured to assist in moving the fluid 34 and / or through the compressor 32. The compressor 32 delivers a flow of compressed fluid 38 (e.g., compressed air) to a combustor 40. The combustor 40 mixes the flow of compressed fluid 38 with a compressed flow of fuel 42 supplied by a fuel supply unit 44 and ignites the mixture to create a flow of combustion gases 46. The flow of combustion gases 46 is then delivered to a turbine component 48, which, similar to the compressor 32, typically includes multi-stage stator guide vanes (not shown) and turbine blades (not shown). The flow of combustion gases 46 drives the turbine component 48 to generate mechanical work. The mechanical work generated in the turbine component 48 drives the compressor 32 via the shaft 50 and can be used to drive external components, such as the generator 52, to generate power and / or produce loads.

[0047] Although the power unit system 12 is Figure 1 The diagram shows a dual-axis configuration utilizing two separate generators 28 and 52; however, it is understood that in other non-limiting examples, the ST system 18 and GT system 30 may share a single axis and, consequently, a single generator. Furthermore, although the power unit system 12 is shown as comprising only a single ST system 18 and a single GT system 30, it is understood that the power unit system 12 may comprise multiple ST systems 18 and / or one or more GT systems 30 configured to generate operating loads and / or power outputs.

[0048] The power unit system 12 may also include a heat recovery steam generator (HRSG) 54, which is fluidly connected to the ST system 18 (e.g., to the HP section 20, IP section 22, and / or LP section 24) and the GT system 30. Figure 1 As shown in the non-limiting example, the HRSG 54 may be fluidly connected and / or coupled to the ST system 18 via one or more discharge conduits 56 to receive discharge fluid (e.g., steam) from the ST system 18, and to supply steam to the ST system 18 via a supply conduit 58. Furthermore, in Figure 1 In a non-limiting example, HRSG 54 may be fluidly connected and / or coupled to GT system 30 via exhaust passage 59, which is coupled to and / or in fluid communication with turbine component 48. Exhaust passage 59 may provide exhaust fluid 60 (e.g., exhaust gas) from GT system 30 to HRSG 54 for use in generating and / or heating steam for ST system 18. Stack (sometimes also called flue or exhaust pipe) 61 of HRSG 54 may vent (excess or used) gas (e.g., exhaust fluid 60) and / or fluid from HRSG 54 to the atmosphere and / or outside power unit system 12, for example, via environment control (not shown).

[0049] The power unit system 12 may also include a condenser 62. The condenser 62 may be in fluid communication with and / or fluidly coupled to various components of the power unit system 12. In a non-limiting example, the condenser 62 may be fluidly connected and / or coupled to the LP section 24 of the ST system 18 via a steam discharge line 64. As is known in the art, the condenser 62 may be configured to condense the discharge flow and / or bypass flow (not shown) from the ST system 18 and / or HRSG 54, and to supply the condensed fluid (e.g., condensate) to the HRSG 54.

[0050] Figure 2 It shows Figure 1 A side cross-sectional view of the HRSG 54 of the power unit system 12. (As shown in...) Figure 2 As shown, and as discussed in this article Figure 1 As discussed, the discharge channel 59 can discharge fluid 60 (e.g., discharge gas) from the GT system 30 (see...). Figure 1The drain passage 59 is coupled to and in fluid communication with the housing 66 of the HRSG 54 to provide drain fluid 60 to the HRSG 54. Specifically, the drain passage 59 is coupled to a removable panel 68 for the housing 66 of the HRSG 54 to fluidly connect the drain passage 59 and the housing 66 and to provide drain fluid 60 to the interior, cavity, or space of the housing 66 of the HRSG 54. The removable panel 68 may be a component or part different from the remaining portion 69, which is removable and / or (releasably) coupled to the remaining portion 69 to form the housing 66. That is, as discussed herein, the removable panel 68 may be coupled and / or attached to the remaining portion 69 to form the housing 66 during the installation process. The discharge fluid 60 may flow through the cavity 66 of the HRSG 54 and / or over multiple components of the HRSG 54, configured to generate and / or heat fluids (e.g., water and / or steam) into steam, which may be supplied to the ST system 18 via the supply conduit 58. Once the discharge fluid 60 has passed through the housing 66 of the HRSG 54, the discharge fluid 60 may be discharged or released from the HRSG 54 via the piping group 61 of the HRSG 54 to an environmental control device (not shown), the atmosphere, and / or outside the power plant system 12.

[0051] like Figure 2 As shown, HRSG 54 may include at least one fluid conduit or pipe 70 (hereinafter, "one or more fluid pipes 70") positioned within housing 66. Specifically, HRSG 54 may include one or more fluid pipes 70 extending through and / or positioned within housing 66 of HRSG 54. One or more fluid pipes 70 of HRSG 54 may include and / or be part of any suitable component, assembly, and / or system that can utilize the heat of discharge fluid 60 to generate and / or heat the fluid into steam for ST system 18. For example, one or more fluid pipes 70 may be pipes or conduits for one or more superheater modules of HRSG 54 that can carry and / or move the generated steam through housing 66 of HRSG 54 to expose it to discharge fluid 60 and ultimately heat the generated steam carried therein. In other examples, one or more fluid pipes 70 may be pipes or conduits for steam generator modules of single-pass (OT) HRSG 54. As discussed herein, one or more fluid conduits 70 may carry and / or move feedwater supplied by feedwater conduit 72 through the housing 66 of HRSG 54 to expose it to discharge fluid 60 and ultimately convert the feedwater into steam for use by ST system 18.

[0052] One or more fluid tubes 70 of HRSG 54 may comprise a single tube formed in a serpentine pattern, or alternatively comprise a plurality of different fluid tubes 70 in fluid communication with each other. Figure 2As shown, one or more fluid conduits 70 may include a deflector 74 positioned within and / or in fluid communication with the housing 66. Furthermore, one or more fluid conduits 70 and the deflector 74 may be coupled to and / or positioned through a strip 76. The strip 76 may be positioned within the housing 66 to substantially support and / or secure the one or more fluid conduits 70 and the deflector 74 within the housing 66 during operation of the HRSG 54. The use of the deflector 74 in one or more fluid conduits 70 allows fluid (e.g., feedwater and / or generated steam) to move multiple times through the housing 66 of the HRSG 54 (e.g., in a serpentine pattern) to increase the exposure of the one or more fluid conduits 70 and the feedwater and / or steam flowing therethrough to the discharge fluid 60 flowing through the housing 66 of the HRSG 54.

[0053] In addition, such as Figure 2 As shown, the HRSG 54 may also include at least one hinged baffle assembly 100 (hereinafter referred to as "baffle assembly 100"). The baffle assembly 100 may be positioned within the housing 66 of the HRSG 54. Furthermore, the baffle assembly 100 may be positioned adjacent to and / or substantially upstream of one or more fluid conduits 70 of the HRSG 54. The baffle assembly 100 may be positioned within the housing 66 to guide the flow of the discharge fluid 60 through the housing 66 of the HRSG 54. That is, the baffle assembly 100 positioned within the housing 66 may at least partially define a desired flow path 78 (shown in dashed lines) for the discharge fluid 60 to flow through the HRSG 54, and may be used to guide the discharge fluid 66 along and / or within the desired flow path 78 through the housing 66 of the HRSG 54. In a non-limiting example, the desired flow path 78 may be defined by, and / or may include, the outer boundary of the baffle assembly 100 and the segments 76 positioned within the housing 66 of the HRSG 54. The desired flow path 78 for discharging fluid 60 may be substantially aligned with, and / or include, most of the one or more fluid tubes 70 positioned between the segments 76. Thus, the baffle assembly 100 may be configured to guide the discharging fluid 60 through the housing 66, and more specifically, during operation of the power unit system 12, flow along the desired flow path 78 through the housing 66 toward and / or in contact with or over the one or more fluid tubes 70 positioned within the HRSG 54 (see [link to relevant documentation]). Figure 1 Guiding the discharge fluid 60 through the desired flow path 78 can substantially improve the operating efficiency of the HRSG 54 (i.e., the heat transfer from the discharge fluid 60 to one or more fluid pipes 70 and the fluid therein).

[0054] Furthermore, by guiding the discharge fluid 60 through the desired flow path 78, the baffle assembly 100 minimizes or prevents leakage of the discharge fluid 60 from the desired flow path 78 and / or into portions of the housing 66 of the HRSG 54 that do not require exposure to the discharge fluid 60. For example, the baffle assembly 100 minimizes or prevents leakage of the discharge fluid 60 from the desired flow path 78 into space 80 of the housing 66. Space 80 may be a space or region of the housing 66 that differs from the space or region containing the desired flow path 78 through which the discharge fluid 60 flows through the housing 66. Space 80 is substantially separated from the desired flow path 78 of the discharge fluid 60 by the baffle assembly 100 and the tube sheet 76 of the HRSG 54. In a non-limiting example, space 80 may accommodate a steering portion 74, a condensate drain conduit (not shown) in fluid communication with at least one steering portion 74, an additive supply conduit (not shown) in fluid communication with at least one steering portion 74, and / or other components utilized by one or more fluid conduits 70, each of which does not need to be exposed to the discharge fluid 60. Although shown as generally open, without components, and / or unfilled, as discussed herein, it is understood that space 80 of housing 66 may contain multiple components contained within and / or used by HRSG 54.

[0055] In a non-limiting example, two baffle assemblies 100 are shown. However, it is understood that more or fewer baffle assemblies 100 may be used within the housing 66 to guide the discharge fluid 60 through the housing 66 and / or at least partially define the desired flow path 78 for the discharge fluid 60 through the housing 66. That is, the housing 66 may include a plurality of baffle assemblies 100, which may be positioned on all internal surfaces or walls and / or circumferentially around the internal region of the housing 66 to guide the discharge fluid 60 through the housing 66 and / or at least partially define the desired flow path 78 for the discharge fluid 60 through the housing 66. For example, the housing 66 may be configured as a generally four-sided container. The internal bottom portion or wall, the internal top / top portion or wall, and the two internal side portions or walls of the housing 66 may all contain baffle assemblies 100. In this example, and similarly Figure 2 As shown in the non-limiting example, the baffle assembly 100 positioned on the inner bottom portion or wall of the housing 66 may at least partially define the bottom boundary of the desired flow path 78 for moving the discharged fluid 60 through the housing 66 (see...). Figure 2 And the baffle assembly 100 positioned on the inner top / top portion or wall of the housing 66 may at least partially define the top / upper boundary of the desired flow path 78 for moving the discharge fluid 60 through the housing 66 (see...). Figure 2Furthermore, the baffle assemblies 100 positioned on each of the side portions or walls of the housing 66 may at least partially define the lateral boundaries for moving the desired flow path of the discharge fluid 60 through the housing 66 (for clarity, Figure 2 (Not shown in the image).

[0056] Figure 3 It shows Figure 2 A side cross-sectional view of the housing 66 and a portion of the baffle assembly 100 of the HRSG 54 shown. Specifically, Figure 3 It shows Figure 2 The image shows a side cross-sectional view of the bottom portion of the housing 66 of the HRSG 54, one or more fluid conduits 70, tube segments 76, and a single baffle assembly 100. The baffle assembly 100, configured to guide the discharge fluid 60 through the housing 66, is discussed in further detail herein and defines a portion of a desired flow path 78 for the discharge fluid 60 through the housing 66. It is understood that similarly numbered and / or named components may operate in a substantially similar manner. Redundant explanations of these components have been omitted for clarity.

[0057] like Figure 3 As shown, the baffle assembly 100 may include a baffle 102. The baffle 102 may be positioned within the housing 66 of the HRSG 54 and may guide the discharge fluid 60 through the housing 66 of the HRSG 54 during operation of the HRSG 54. Furthermore, as discussed herein, the baffle 102 may at least partially define a desired flow path 78 for moving the discharge fluid 60 through the HRSG 54. The baffle 102 of the baffle assembly 100 may be formed as a solid, single-piece component. Furthermore, the baffle 102 may be formed of any generally rigid material that prevents the discharge fluid 60 from flowing through it. In a non-limiting example, the baffle 102 may be formed of metal, metal alloy, ceramic, polymer, and any other material having similar properties and / or characteristics and capable of withstanding the environment of the HRSG 54.

[0058] In a non-limiting example, the baffle 102 of the baffle assembly 100 may include a first end 104 and a second end 106. The first end 104 may be positioned adjacent to and generally downstream of the discharge passage 59, which is coupled to and / or communicates with the housing 66 of the HRSG 54. The second end 106 may be positioned axially opposite to and generally downstream of the first end 104 of the baffle 102. Furthermore, as... Figure 3As shown, the baffle 102 may include a first surface 108 and a second surface 110. Each of the first surface 108 and the second surface 110 may extend between a first end 104 and a second end 106, respectively. In a non-limiting example, the first surface 108 may be included within and / or define the desired flow path 78 of the discharge fluid 60 flowing through the housing 66 of the HRSG 54. Thus, during operation of the power system 12 and / or the HRSG 54, the first surface 108 of the baffle 102 may also be substantially exposed to and / or contacted by the discharge fluid 60 flowing through the housing 66. The second surface 110 may be positioned opposite the first surface 108 of the baffle 102 and therefore may not be exposed to the discharge fluid 60 flowing through the housing 66 of the HRSG 54. Figure 3 As shown, the second surface 110 of the baffle 102 may be positioned adjacent to and / or exposed to the space 80 formed within the housing 66.

[0059] like Figure 3 As shown, the deflector assembly 100 may also include a hinge component 112. The hinge component 112 may be fixed relative to the housing 66 and may be positioned within the housing 66 of the HRSG 54. Specifically, in one example, the hinge component 112 may be positioned on and / or fixed relative to a removable panel 68 of the housing 66. In one Figure 3 In the non-limiting example shown, the hinge component 112 may be positioned, coupled to, and / or attached to a first inner surface 82 of a removable panel 68 of the housing 66 for the HRSG 54. Figure 3 As shown, a first inner surface 82 may be formed on a portion of the removable panel 68 of the housing 66, which is positioned adjacent to and downstream of the discharge channel 59 (see Figure 1). Figure 2 The discharge passage provides the discharged fluid 60 to the housing 66 of the HRSG 54. Furthermore, in a non-limiting example, the first inner surface 82 of the removable panel 68 of the housing 66 may be substantially parallel to the... Figure 3 The arrows in the diagram indicate the flow direction of the discharge fluid 60 flowing through the housing 66 of the HRSG 54. The hinge component 112 can be positioned, coupled to, and / or attached to the first inner surface 82 using any suitable joining technique, process, and / or component. In a non-limiting example, the hinge component 112 can be substantially fixed (e.g., welded, brazed, riveted, etc.) or releasably coupled (e.g., nuts and bolts, screws, etc.) to the first inner surface 82 of the removable panel 68 of the housing 66. Alternative locations within the housing 66 for the hinge component 112 will be discussed herein.

[0060] Furthermore, hinge component 112 may be coupled to the first end 104 of the deflector 102. Specifically, hinge component 112 may be coupled to, attached to, and / or supported by the first end 104 of the deflector 102. Hinge component 112 may be formed as any suitable hinge component or assembly that may be capable of adjusting the rotational position of the deflector 102 within the housing 66 of the HRSG 54. That is, hinge component 112 may be formed as any suitable hinge component or assembly, such as a pivot hinge, which may be configured to move the deflector 102 in one direction (ROT) and / or rotate it substantially about the first end 104 to adjust the rotational position of the deflector 102 within the housing 66. As discussed herein, hinge component 112, including the deflector 102, may be installed within the housing 66 of the housing 66 and / or the housing 66 of the power unit system 12 before the removable panel 68 is installed (see Figure 1 A removable panel 68 is attached to and / or attached to the housing 66 to reduce the installation and / or assembly time of the HRSG 54 prior to its use within the power unit system 12.

[0061] The baffle assembly 100 may also include an extension plate 118. For example... Figure 3 As shown, the extension plate 118 may be positioned adjacent to the second end 106 of the baffle 102 and generally downstream of the hinge assembly 112 and the first end 104 of the baffle 102, respectively. The extension plate 118 may also be configured to bear, contact, and / or support the second surface 110 of the baffle 102. For example, a portion of the baffle 102 including the second end 106 may be positioned above and / or extend over at least a portion of the extension plate 118. Thus, when the baffle assembly 100 is contained within the housing 66 of the HRSG 54, the second surface 110 of the portion of the baffle 102 extending over the extension plate 118 may be borne, directly contacted, and / or rested upon by the extension plate 118.

[0062] exist Figure 3 In the non-limiting example shown, the extension plate 118 may also be positioned on, coupled to, and / or attached to the segment 76 of the HRSG 54, and may extend from the segment 76 toward the baffle 102. As discussed herein, the extension plate 118 may be positioned on, coupled to, and / or attached to the segment 76 of the HRSG 54, and may extend from the segment 76 to substantially receive, contact, and / or support the baffle 102 of the baffle assembly 100 within the housing 66 of the HRSG 54. The extension plate 118 may be positioned on, coupled to, and / or attached to the segment 76 using any suitable joining technique, process, and / or component. In the non-limiting example, the extension plate 118 may be substantially fixed (e.g., welded, brazed, riveted, etc.) or releasably coupled (e.g., nuts and bolts, screws, etc.) to the segment 76. In other non-limiting examples (see... Figure 11 and 12 The extension plate 118 may be positioned on, coupled to, attached to, and / or structurally supported by the housing 66 of the HRSG 54. As discussed herein, the extension plate 118 of the baffle assembly 100 may be formed as a generally rigid component and / or may be formed of any generally rigid material that supports portions of the baffle 102 that contact the extension plate 118 and additional components of the baffle assembly 100. In a non-limiting example, the extension plate 118 may be formed of metal, metal alloy, ceramic, polymer, and any other material having similar properties and / or characteristics and capable of withstanding the environment of the HRSG 54.

[0063] The deflector assembly 100 may also include a first splitter plate 120. Brief deflection. Figure 4 And continue to refer to Figure 3 The first diverter plate 120 of the baffle assembly 100 may be positioned adjacent to and extending above or over the second end 106 of the baffle 102. The first diverter plate 120 may also directly contact the first surface 108 of the baffle 102. That is, the first diverter plate 120 may directly contact and / or apply force to the first surface 108 of the baffle 102 to impact, hold, and / or compress the baffle 102 against the extension plate 118. Furthermore, and as discussed herein, the first diverter plate 120 may guide the discharge fluid 60 through the housing 66 of the HRSG 54, and / or may be configured to guide or move the discharge fluid 60 over different portions or components (e.g., support members) of the baffle assembly 100 and / or into a desired flow path 78. The first diverter 120 may be formed of any suitable material that can contact and apply force to the first surface 108 of the baffle 102 to hold or compress the baffle 102 against the extension plate 118 during operation of the HRSG 54. For example, the first diverter 120 may be formed of any suitable material that has generally malleable and / or flexible properties or attributes. In a non-limiting example, the first diverter 120 may be formed of a metal, a metal alloy, a shape memory alloy, a polymer, etc.

[0064] The first diverter 120 may be positioned on, coupled to, and / or attached to the first support member 122 of the baffle assembly 100. As discussed herein, the first support member 122 may hold the first diverter 120 within the housing 66 and / or support the first diverter 120 when it contacts and / or applies force to the baffle 102. In one Figure 3 and 4In the non-limiting example shown, the first diverter 120 may be releasably coupled to the first support member 122 of the baffle assembly 100 via fasteners 124 positioned between the first diverter 120 and the first support member 122. The fasteners 124 may be any suitable component or assembly that releasably couples the first diverter 120 to the first support member 122, including, but not limited to, bolts and nuts, snap-fit ​​engagements, screws, forks and cotter pins, etc. In other non-limiting examples, the first diverter 120 may be attached to the first support member 122 of the baffle assembly 100 using any suitable component or process, including, but not limited to, riveting, melting, brazing, welding, etc. Figure 3 and 4 As shown, a first support member 122 of the baffle assembly 100 may be positioned on and / or extending from the extension plate 118, adjacent to and downstream of the second end 106 of the baffle 102. As discussed herein, the first support member 122 may be positioned on the extension plate 118 and adjacent to the second end 106 of the baffle 102 to partially position the first diverter plate 120 above and / or allow the first diverter plate 120 to contact the baffle 102. For example, the first diverter plate 120 coupled to the first support member 122 may extend from the first support member 122 toward and / or above the second end 106 of the baffle 102, such that the first diverter plate 120 may directly contact and apply force to the first surface 108 of the baffle 102 to hold or compress the baffle 102 against the extension plate 118 during operation of the HRSG 54.

[0065] exist Figure 3 and 4 In the non-limiting example shown, the first splitter 120 may include a base section 126. The base section 126 of the first splitter 120 may directly contact the first surface 108 of the baffle 102. Furthermore, as... Figure 3 and 4As shown, the base section 126 of the first splitter 120 may be generally planar and / or parallel to the first surface 108 of the baffle 102 to ensure and / or optimize the contact between the base section 126 of the first splitter 120 and the first surface 108 of the baffle 102. In a non-limiting example, the first splitter 120 may also include an angled section 128. The angled section 128 may be positioned adjacent to the base section 126 and may extend (at an angle) between the base section 126 and the connecting section 130 of the first splitter 120. Furthermore, the angled section 128 may be angled, non-planar, and / or not parallel to the first surface 108 of the baffle 102. The angled section 128 may extend substantially at an angle and / or at an angle between the base section 126 and the connecting section 130 to divert and / or guide the discharge fluid 60 flowing on the baffle 102 toward one or more fluid conduits 70 and / or over different portions or components of the baffle assembly 100. For example, as discussed herein, the angled section 128 may guide the discharge fluid over the first support member 122 of the baffle assembly 100 that bears the first diverter 120. Furthermore... Figure 3 and 4 In the non-limiting example shown, the connecting section 130 of the first diverter 120 may be positioned adjacent to the angled section 128 and opposite to the base section 126. The connecting section 130 of the first diverter 120 may extend toward, be supported by, and / or be connected to the first support member 122 of the deflector assembly 100. As discussed herein, a fastener 124 may contact and / or move through the connecting section 130 to releasably connect the first diverter 120 to the first support member 122.

[0066] like Figure 3As shown, the baffle assembly 100 may also include a sealing plate 132 positioned on a first inner surface 82 of a housing 66, such as that used in HRSG 54. The sealing plate 132 may be positioned adjacent to, connected to, and / or attached to, the first inner surface 82 downstream of the hinge member 112, and may also be positioned adjacent to a first end 104 of the baffle 102. Because it is positioned on, connected to, and / or attached to the first inner surface 82 of the housing 66, the sealing plate 132 may be positioned below the baffle 102. Specifically, the sealing plate 132, positioned adjacent to the hinge member 112, may be positioned below a second surface 110 of the baffle 102 and may substantially contact, press against, and / or abut against it to form a seal. The sealing plate 132 may contact the second surface 110 of the baffle 102 to form a seal for the baffle assembly 100, which in turn substantially prevents the discharge fluid 60 from flowing between the hinge member 112 and the baffle 102, and substantially prevents the discharge fluid 60 from leaking into the space 80 below the baffle 102. The sealing plate 132 may be formed of any suitable material that can form a seal with the baffle 102 and prevent the discharge fluid 60 from leaking into the space 80. For example, the sealing plate 132 may be formed of any suitable material having a generally extensible, stretchable, bendable, and / or flexible characteristic or property. In a non-limiting example, the sealing plate 132 may be formed of metal, metal alloy, shape memory alloy, polymer, foam, etc.

[0067] To increase rigidity and / or weight to the baffle 102, the baffle assembly 100 may include a reinforcement 134. Figure 3 In the non-limiting example shown, the reinforcement 134 may be positioned on, connected to, and / or attached to the second surface 110 of the baffle 102, and may extend into the space 80 of the housing 66. Other non-limiting examples discussed herein (see...) Figure 9The reinforcement 134 may be positioned on, connected to, and / or attached to the first surface 108 of the baffle 102. The reinforcement 134 may be positioned between the first end 104 and the second end 106 of the baffle 102, respectively. Furthermore, as discussed herein, the reinforcement 134 may be spaced apart or separated from the housing 66 and the extension plate 118 by gaps to avoid any obstruction during directional (ROT) rotation of the baffle 102. The reinforcement 134 may be formed of any suitable material that can provide or add rigidity and / or weight to the baffle 102. In a non-limiting example, the reinforcement 134 may be formed of metal, metal alloy, polymer, ceramic, etc. As discussed herein, during operation, the baffle 102 may be exposed to the high-temperature discharge fluid 60, which may subsequently allow the baffle 102 to expand, lengthen, and / or deform based on its material composition and / or properties. As discussed herein, the reinforcement 134 helps the baffle 102 prevent leakage of the discharged fluid 60 by providing rigidity to prevent / reduce the growth or deformation of the baffle 102 and / or by adding weight to ensure that the baffle 102 maintains contact with the corresponding components of the baffle assembly 100 (e.g., sealing plate 132, extension plate 118, etc.).

[0068] Figures 5 to 8 The installation process is shown within the housing 66 of the HRSG 54. Figure 3 The hinged baffle assembly 100 (see Figure 3 A side cross-sectional view of ( ). Specifically, Figure 5 A side cross-sectional view of a removable panel 68 is shown, which includes a hinge component 112 and a baffle 102 mounted therein. Figures 6 to 8 A side cross-sectional view of the baffle assembly 100 undergoing the installation process within the housing 66 of the HRSG 54 is shown. Besides guiding the discharge fluid 60 through the housing 66 and / or defining the desired flow path 78 within the housing 66, and as discussed herein, the use or combination of the baffle assembly 100 within the housing 66 of the HRSG 54 can reduce and / or improve installation time and / or accuracy. It is understood that components with similar numbers and / or names can operate in a substantially similar manner. Redundant explanations of these components have been omitted for clarity.

[0069] As discussed herein, the removable panel 68 may be a separate component or part that can be attached to the remaining portion 69 to collectively form the housing 66. Figure 5 In the non-limiting example shown, the removable panel 68 is shown in a "pre-installed state" and may not yet be attached to the remainder 69 of the housing 66. As discussed herein, in the pre-installed state, the removable panel 68 may be positioned outside and / or off-site of the power unit system 12 (see [link to documentation]). Figure 1For example, at a manufacturing site or factory, the removable panel can be transported to the location or site of the power unit system 12 for installation. Furthermore, in a pre-installed state, the removable panel 68 may include a portion of the baffle assembly 100 on which it is mounted or included. For example, a hinge component 112 of the baffle system 100 may be positioned on, coupled to, and / or attached to a first inner surface 82 of the removable panel 68, and a first end 104 of the baffle plate 102 may be coupled to, attached to, and / or supported by the hinge component 112. Additionally, in the pre-installed state of the removable panel 68, a sealing plate 132 (optionally shown in dashed lines) may also be positioned adjacent to, coupled to, and / or attached to a first inner surface 82 of the removable panel 68, adjacent to, and / or attached to the hinge component 112. In the pre-installed state, hinge component 112 allows the deflector 102 to rotate above and / or be positioned directly above the removable panel 68; different from and / or opposite to it (comparison). Figure 5 and Figure 3 Or 8). The baffle 102 may be positioned directly above the removable panel 68 to reduce the size of the pre-installed assembly of the removable panel 68, the baffle 102, the hinge component 112, and the sealing plate 132, and to assist and / or protect the components during transport or delivery to the location or site of the HRSG 54 and / or the power unit system 12.

[0070] Parts of the deflector assembly 100 (e.g., hinge component 112, deflector plate 102, etc.) can be pre-installed on the removable panel 68 to reduce and / or improve the installation time and / or accuracy of the deflector system 100 within the HRSG 54. For example, by mounting and / or positioning the hinge component 112 and deflector plate 102 (the largest components of the deflector assembly 100) on the removable panel 69 before attaching the removable panel 68 to the remaining portion 69 of the housing 66, the operator and / or user have more leeway and / or space for positioning the hinge component 112 and deflector plate 102 on the removable panel 68. Furthermore, when the hinge component 112 and deflector plate 102 are mounted and / or positioned on the removable panel 68, the operator and / or user have a greater operating position and / or the ability to move the removable panel 68. Thus, the installation and / or positioning of the hinge component 112 and the baffle 102 on the removable panel 68 can be performed more easily and / or more precisely than in-situ installation (e.g., in the housing 66 of the HRSG 54).

[0071] Furthermore, due to the ability of the baffle 102 to rotate in the directional orientation (ROT) about the hinge member 112, positioning the hinge member 112 and the baffle 102 on the removable panel 68 before attaching the removable panel 68 to the remainder 69 of the housing 66 reduces and / or improves the installation time and / or accuracy of the baffle system 100 within the HRSG 54. That is, because the hinge member 112 and the baffle 102 are positioned on the removable panel 68 in a pre-installed state, once the removable panel 68 is attached to the remainder 69 to form the housing 66, the baffle 102 can simply rotate in the directional orientation (ROT) and be positioned in the desired and / or operating position within the HRSG 54 within seconds. (Refer to...) Figure 6-8 The installation process of the baffle assembly 100 can be discussed in this article. Figure 6 As shown, the removable panel 68 can be coupled to and / or attached to the remaining portion 69 to form the housing 66 of the HRSG 54. In a non-limiting example, and similar to that described herein... Figure 5 In the pre-installed state discussed, when a coupling or engagement process is performed between the removable panel 68 and the remaining portion 69, the baffle 102 can be rotated and / or positioned above the removable panel 68. Furthermore, the baffle 102 can be positioned above the removable panel 68 to allow the operator or user of the power unit system 12 easier installation, positioning, coupling, and / or attachment of the extension plate 118 relative to the segment 76 of the HRSG 54. That is, by rotating and / or positioning the baffle 102 above the removable panel 68, the space between the removable panel 68 and the segment 76 can be substantially unobstructed or open, and the operator or user can access the segment 76 to install the extension plate 118 thereon. In another non-limiting example, as discussed herein, the extension plate 118 can be pre-installed on the segment 76 such that when the segment 76 is secured within the housing 66 of the HRSG 54, the extension plate 118 may already be positioned, coupled, and / or attached to the segment 76. To further reduce installation time, the removable panel 68 can also be installed and / or connected to the remaining portion 69 while the extension plate 118 is installed or connected to the segment 76.

[0072] Turning Figure 7 Once the removable panel 68 is mounted and / or coupled to the remaining portion 69 to form the housing 66, and the extension plate 118 is mounted or coupled to the tube segment 76, the baffle 102 can be rotated axially (ROT) to the desired and / or operating position. That is to say, and as Figure 7As shown in the various stages indicated by dashed lines, the baffle 102 can be rotated axially (ROT) from a pre-installed position (shown in dashed lines) above the first inner surface 82 of the removable panel 68 to a desired and / or operational position. In the desired and / or operational position, as discussed herein, the second surface 110 of the baffle 102 can be supported by, in direct contact with, and / or rest on the extension plate 118. If not positioned on the removable panel 68 in the pre-installed state (see...), Figure 5 The sealing plate 132 can be positioned on the removable panel 68 prior to the rotating baffle 102. Furthermore, and as... Figure 7 As shown, after the removable panel 68 is installed and / or coupled to the remaining portion 69, the first support member 122 of the baffle assembly 100 may also be positioned on and / or extending from the extension plate 118, adjacent to and downstream of the second end 106 of the baffle plate 102. In another non-limiting example, and similar to the extension plate 118, the first support member 122 may be pre-installed on the extension plate 118 such that when the extension plate 118 is coupled and / or attached to the tube segment 76 of the HRSG 54, the first support member 122 may already be positioned, coupled, and / or attached to the extension plate 118.

[0073] Once the baffle 102 has rotated in the directional (ROT) direction and is positioned in the desired and / or operating position, and the first support member 122 is coupled to the extension plate 118, the first splitter 120 can be installed in the HRSG 54. As discussed herein, and as... Figure 8 As shown, the first diffuser 120 can be coupled to and / or supported by the first support member 122 via fastener 124, and can extend over the second end 106 of the deflector 102. Furthermore, when installed within the HRSG 54, the first diffuser 120 can directly contact and / or apply force to the first surface 108 of the deflector 102 to impact, hold, and / or compress the deflector 102 against the extension plate 118. This is achieved by positioning and / or mounting the deflector 102 and hinge member 112 onto the removable panel 68 in a pre-installed state (see...). Figure 5 ), to provide operators or users with more space or passage within the housing 66 to install additional components of the baffle assembly 100 (e.g., extension plate 118); Figure 6 And / or pre-installing components of the baffle assembly 100 to different components of the baffle plate 100 and / or HRSG 54 can allow the baffle assembly 100 to be installed in the HRSG 54 faster and / or more accurately than the conventional installation process.

[0074] Figure 9 and 10 A view showing another non-limiting example of the baffle component 100 is illustrated. Specifically, Figure 9 A side cross-sectional view of the bottom portion of the housing 66 of the HRSG 54, one or more fluid tubes 70, tube segments 76, and baffle assembly 100 is shown, and Figure 10 It shows Figure 9 An enlarged view of a portion of the deflector assembly 100. It is understood that components with similar numbers and / or names may function in a generally similar manner. For clarity, redundant explanations of these components have been omitted.

[0075] exist Figure 9 and 10 The non-limiting examples shown are different from those in this document. Figure 3 and 4 As shown and discussed in the examples, the hinge component 112 of the deflector assembly 100 can be positioned on different portions of the removable panel 68 of the housing 66. For example, the hinge component 112 can be positioned on, coupled to, and / or attached to a second inner surface 84 of the removable panel 68 of the housing 66 for the HRSG 54. The second inner surface 84 can be different from and / or positioned adjacent to the first inner surface 82. That is, and as... Figure 9 As shown, a second inner surface 84 may be formed on a portion of the removable panel 68 of the housing 66, positioned adjacent to and downstream of the first inner surface 82. The second inner surface 84 may be substantially perpendicular to the... Figure 9 The arrows in the diagram represent the flow direction of the discharged fluid 60 flowing through the housing 66 and / or the first internal surface 82 of the HRSG 54. As discussed herein, the hinge component 112 may be positioned, coupled to, and / or attached to the second internal surface 84 of the removable panel 68 of the housing 66, and adjacent to the first internal surface 82, using any suitable engagement technique, process, and / or component.

[0076] exist Figure 9 and 10 In the non-limiting example shown, the hinge component 112 may also be coupled to the support bracket 135 of the baffle assembly 100. That is, in order to position the baffle 102 within the housing 66 to guide the discharge fluid 60 through the housing 66 and / or define a desired flow path 78 for the discharge fluid 60, the hinge component 112 may be coupled to a second inner surface 84 substantially adjacent to the first inner surface 82. Furthermore, and as... Figure 9 and 10As shown, a portion of the hinge component 112 may even extend above the second inner surface 84 of the removable panel 68 of the housing 66. To provide additional support and / or ensure the hinge component 112 is stable within the housing 66, the hinge component 112 of the deflector assembly 100 may also be coupled to, coupled to, and / or attached to, a support bracket 135 positioned on, coupled to, and / or attached relative to the first inner surface 82 of the removable panel 68 of the housing 66 for the HRSG 54. The support bracket 135 may be any suitable bracket and / or component (e.g., an L-bracket) that can be configured to support and / or secure the hinge component 112 within the housing 66 of the HRSG 54.

[0077] In addition, Figure 9 and 10 The non-limiting examples shown are different from those in this document. Figure 3 and 4 As shown and discussed in the examples, the baffle assembly 100 may further include a second support member 136 and a second splitter plate 138. The second support member 136 may differ from the first support member 122, and the second splitter plate 138 may differ from the first splitter plate 120. Figure 9 and 10 As shown, a second support member 136 may be formed on the baffle 102 and may be supported and / or coupled to the second diverter 138. Specifically, the second support member 136 may be formed on and / or extend from the first surface 108 of the baffle 102, adjacent to and downstream of the first end 104 of the baffle 102. The second diverter 138 may be supported, positioned on, coupled to, and / or attached to the second support member 136 of the baffle assembly 100 (e.g., fastener 140). The second diverter 138 may extend from the second support member 136 and may be positioned adjacent to and extending above the first end 104 of the baffle 102. Furthermore, the second diverter 138 may extend above and / or be positioned above a hinge member 112 coupled to a second inner surface 84, and a support bracket 135 coupled to a first inner surface 82. The second diverter 138 may also extend above and / or directly contact the first internal surface 82 of the housing 66 for the HRSG 54. As similarly discussed herein with respect to the first diverter 120, the second diverter 138 may be formed within the housing 66 to guide the discharge fluid 60 or to move it over different portions or components of the baffle assembly 100 (e.g., hinge component 112, support bracket 135). Furthermore, the second diverter 138 may directly contact the first internal surface 82 to form a seal for the baffle assembly 100, which in turn substantially prevents the discharge fluid 60 from flowing below the second diverter 138, between the hinge component 112 and the baffle 102, and into the space 80.

[0078] In addition, such as Figure 9 As shown, and as discussed herein, reinforcement 134 may be positioned, connected to, and / or attached to the first surface 108 of baffle 102 to add rigidity and / or weight to baffle 102. In a non-limiting example, reinforcement 134 positioned, connected to, and / or attached to the first surface 108 of baffle 102 may be exposed to discharge fluid 60 and / or may be positioned within a desired flow path 78 for discharge fluid 60 flowing through housing 66 of HRSG 54. As similarly discussed herein, reinforcement 134 may be positioned between the first end 104 and the second end 106 of baffle 102 and may be spaced apart or separated from housing 66 and extension plate 118 by a gap to avoid any obstruction when baffle 102 is rotated in the directional (ROT) direction.

[0079] Figure 11 and 12 A non-limiting example of a baffle assembly 100 utilized within the housing 66 of the HRSG 54 is shown. Specifically, Figure 11 A side cross-sectional view of the housing 66 and the bottom portion of the baffle assembly 100 of the HRSG 54 is shown, and Figure 12 It shows Figure 11 Top view of the deflector assembly 100. The first deflector 102A, the first hinge component 112A, the first splitter 120A, the first support component 122A, and the first reinforcement 134A are generally similar to those described herein. Figure 3 and 4 The baffle 102, hinge component 112, splitter 120, support component 122, and reinforcement 134 discussed herein may operate in a substantially similar manner. Redundant explanations of these components have been omitted for clarity. Furthermore, for clarity, the sealing plate (see sealing plate 132) has been omitted from the baffle 100. Figure 3 However, it is understood that, in relation to the content of this article... Figure 3 Similarly, the first sealing plate can be positioned on the first inner surface 82 of the housing 66, and the second sealing plate can be positioned on the first extension plate 118A.

[0080] like Figure 11 and 12 As shown, and different from the content in this article. Figure 2-5 In a non-limiting example as discussed, the first extension plate 118A of the baffle assembly 100 may not be coupled to and / or attached to the tube segment 76. Instead, the first extension plate 118A may be positioned on, coupled to, attached to, and / or structurally supported by the housing 66 of the HRSG 54. For example, and as... Figure 11As shown, the strut 86 may extend from the housing 66 to support, retain, and / or secure the first extension plate 118A within the housing 66 of the HRSG 54. In another non-limiting example (not shown), the first extension plate 118A may be positioned on, coupled to, attached to, and / or extended from the sidewall of the housing 66 for the HRSG 54.

[0081] In addition, such as Figure 11 and 12 As shown, the deflector assembly 100 may further include a second deflector plate 102B, a second hinge component 112B, a second extension plate 118B, a second splitter plate 120B, a second support component 122B, and a second reinforcement member 132B. The second deflector plate 102B, the second hinge component 112B, the second extension plate 118B, the second splitter plate 120B, the second support component 122B, and the second reinforcement member 132B may operate in a manner substantially similar to components with similar names or numbering discussed herein. However, in Figure 11 and 12 In the non-limiting example shown, the second baffle 102B, the second hinge component 112B, the second extension plate 118B, the second splitter plate 120B, the second support component 122B, and the second reinforcement 132B may be positioned in different portions and / or on different components of the baffle assembly 100 and / or housing 66 of the HRSG 54.

[0082] For example, a second baffle 102B may extend between a first extension plate 118A and a second extension plate 118B. Furthermore, the second baffle 102B may include a first end portion 104B positioned adjacent to the second end portion 106A of the first baffle 102A, the first extension plate 118A, and / or the first support member 122A. A second hinge member 112B of the baffle assembly 100 may be coupled to the first end portion 104B of the second baffle 102B and may be positioned on, coupled to, and / or attached to the first extension plate 118A, adjacent to and downstream of the second end portion 106A of the first baffle 102A, and / or adjacent to and downstream of the first support member 122A. The second extension plate 118B may be positioned adjacent to and capable of receiving / contacting the second end portion 106B of the second baffle 102B. Furthermore, the second extension plate 118B may be positioned on, connected to, and / or attached to the segment 76 of the HRSG 54, and may extend from the segment 76 toward the second baffle 102B. The second diverter plate 120B may be positioned adjacent to the second end 106B of the second baffle 102B. Furthermore, the second diverter plate 120B may directly contact and / or apply force to the first surface 108B of the second baffle 102B to impact, hold, and / or compress the second baffle 102B against the second extension plate 118B. The second support member 122B may be positioned on the second extension plate 118B, adjacent to the second end 106B of the second baffle 102B, and may support the second diverter plate 120B.

[0083] The technical effect is to provide a hinged baffle assembly for the heat recovery steam generator (HRSG) of a combined cycle power plant system, which reduces and / or improves installation time and / or accuracy, improves the flow of discharge fluid within the HRSG, and minimizes or prevents leakage of discharge fluid from the desired flow path of the HRSG.
