Description

Technical Field

[0001] This invention relates to the field of boiler combustion monitoring technology, and in particular to a boiler combustion monitoring method and device. Background Technology

[0002] With increasingly stringent national environmental protection requirements, combustion technology necessitates continuous innovation and upgrading. The development of new technologies relies heavily on effective testing equipment. Large international combustion technology companies typically possess their own corresponding testing facilities. However, in China, such equipment is lacking. Therefore, developing a range of advanced combustion technologies requires equipment capable of simulating actual combustion processes, such as in power plant boilers.

[0003] Boiler combustion efficiency can be assessed by detecting the carbon content of boiler fly ash. Real-time monitoring of fly ash carbon content helps guide the correct adjustment of the air-coal ratio, improving boiler combustion control. Reasonable control of fly ash carbon content helps reduce power generation costs and improve the economic efficiency of unit operation. Therefore, a combustion efficiency monitoring method is needed to facilitate rapid data recording and maintenance feedback by staff.

[0004] Currently available temporary testing equipment suffers from several drawbacks. Firstly, the reaction time is difficult to control, often resulting in errors due to oversight. Secondly, operating multiple devices is cumbersome, leading to analysis delays. These factors contribute to inaccurate measurements reflecting the current boiler combustion conditions. Furthermore, temporary testing equipment requires assembly for different testing needs, with wiring being a crucial step. Operators typically use manual connections, removing the insulation from both ends of the wires to expose the metal wires, twisting the wires together, and then securing them with insulating tape. However, this commonly used wiring method presents numerous problems and poses a safety hazard. Summary of the Invention

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0032] This embodiment provides a boiler combustion monitoring method, which can help guide the correct adjustment of the air-coal ratio and improve the boiler combustion control level. The method includes the following steps:

[0033] Specifically, flue gas is injected into monitoring unit 100; the carbon dioxide concentration at the inlet is detected and recorded; oxygen is injected into the reactor to ensure that carbon particles in the flue gas can be fully combusted in the furnace; and the carbon dioxide concentration at the outlet is detected and recorded.

[0034] It should be noted that the amount of residual carbon carried in the flue gas is determined by the difference in carbon dioxide concentration at different ports, thus obtaining the concentration of carbon dioxide in the flue gas after combustion. The amount of residual carbon carried in the flue gas entering the flue gas channel is determined by the increased concentration of carbon dioxide. That is, the amount of residual carbon carried in the flue gas entering the flue gas channel is directly proportional to the concentration of newly added carbon dioxide. The higher the measured concentration of newly added carbon dioxide, the more residual carbon is carried in the flue gas; conversely, the lower the measured concentration of newly added carbon dioxide, the more residual carbon is carried in the flue gas.

[0035] In summary, real-time monitoring of fly ash carbon content facilitates rapid data recording and maintenance by staff, which helps guide the correct adjustment of the air-coal ratio and improves boiler combustion control. Furthermore, reasonable control of fly ash carbon content helps reduce power generation costs and improve the economic efficiency of unit operation. Example 2

[0036] Reference Figures 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that it also includes the specific structure of the monitoring unit 100, which can facilitate the temporary installation of equipment, reasonably control the reaction time, and quickly control the switching between different equipment, thereby avoiding oversights caused by being overwhelmed.

[0037] Specifically, the monitoring unit 100 includes a transfer component 101, a reaction component 102 disposed on the transfer component 101, and a connection control component 103 electrically connected to the reaction component 102.

[0038] Furthermore, the transfer assembly 101 includes a base plate 101a, rollers 101b disposed at the four corners of the bottom of the base plate 101a, a control area 101c disposed at one end of the base plate 101a, and a transfer handle 101d disposed at one end of the base plate 101a. The control area 101c facilitates the operation of the connection and control assembly for temporary wiring, equipment installation, and cyclic control by the operator.

[0039] Furthermore, the reaction assembly 102 includes a reactor 102a, an air inlet 102b disposed on one side of the reactor 102a, an air outlet 102c disposed on one side of the reactor 102a, a first acquisition module 102d disposed on the air inlet 102b, a second acquisition module 102e disposed on the air outlet 102c, an oxygen generator 102f connected to the reactor 102a, an air pump 102g connected to the air outlet 102c, and a filter box 102h connected to the air pump 102g.

[0040] It should be noted that the reactor 102a can be equipped with a heat source such as an electric heating tube to heat and burn the oxygen and residual carbon particles in the flue gas, and the filter box 102h is used to filter the flue gas after the reaction. Both the first acquisition module 102d and the second acquisition module 102e can use existing carbon dioxide concentration detection equipment.

[0041] In operation, flue gas is injected into the inlet 102b of the reactor 102a; the carbon dioxide concentration at the inlet 102b is detected and recorded by the first acquisition module 102d; oxygen is injected through the hose connecting the oxygen generator 102f to the reactor to ensure complete combustion of carbon particles in the flue gas within the furnace; then, the carbon dioxide concentration at the outlet 102c is detected and recorded by the second acquisition module 102e. Finally, the flue gas is extracted from the reactor and discharged into the filter box 102h by starting the air pump 102g.

[0042] Furthermore, the connection control assembly 103 includes a housing 104, a tensioning and unlocking connector 105 disposed at one end inside the housing 104, a delay switching connector 106 disposed on one side of the tensioning and unlocking connector 105, two sets of power supply components 107 respectively connected to both sides of the housing 104, a first power line 108 partially disposed inside the housing 104 and electrically connected to the oxygen concentrator 102f, and a second power line 109 partially disposed inside the housing 104 and electrically connected to the air pump 102g.

[0043] Furthermore, the housing component 104 includes a longitudinal groove 104a disposed on the top of the housing component 104 and a transverse groove 104b penetrating one end of the housing component 104, and a hollow storage plate 104c disposed below the transverse groove 104b and connected to the inner wall of the housing component 104; one end of the housing component 104 is provided with a plug port adapted to the first power line 108 and the second power line 109.

[0044] Furthermore, the tensioning and unlocking connector 105 includes a support plate 105a, springs 105b connected to one side of the bottom of the support plate 105a and the inner wall of the housing 104 respectively, a first contact plate 105c and a second contact plate 105d symmetrically arranged on both sides of the support plate 105a, two sets of arc-shaped hollow driven plates 105e symmetrically arranged on both sides of the support plate 105a, an L-shaped spacer plate 105f inserted into the longitudinal groove 104a, and a spacer plate 105f connected to the L-shaped groove 104a. The fixed-distance plate 105f is connected to the bottom of a movable block 105g located in the middle of the bearing plate 105a, two sets of telescopic rods 105h symmetrically arranged on both sides of the movable block 105g, an arc-head tensioning block 105i connected to the extended end of the telescopic rod 105h, and a friction pad 105j located outside the arc-head tensioning block 105i; the friction pad 105j can be made of friction material to increase the friction between the pad and the line, and to avoid the risk of the line falling off after clamping.

[0045] The L-shaped spacer plate 105f has an insertion hole 105f-1 at one end, and an insertion rod 105f-2 is provided on one side of the L-shaped spacer plate 105f. The insertion rod 105f-2 is provided with an insertion plate and an insertion rod. The size of the insertion rod is adapted to the size of the insertion hole 105f-1 and is used to fix the L-shaped spacer plate 105f.

[0046] Preferably, the groove in the middle of the hollow driven plate 105e is adapted to the extended end of the telescopic rod 105h and moves with the telescopic rod 105h when the inner wall contacts the extended end of the telescopic rod 105h. When the telescopic rod 105h is retracted to its maximum, the hollow driven plate 105e is on the same straight line as the arc-head tensioning block 105i, which facilitates cyclic clamping and fixation, and avoids failure due to the hollow driven plate 105e failing to cooperate with the arc-head tensioning block 105i.

[0047] Furthermore, the delay switching component 106 includes an L-shaped offset frame 106a, a first connecting piece 106b and a second connecting piece 106c symmetrically arranged on both sides of the L-shaped offset frame 106a, a short rack 106d connected to one end of the L-shaped offset frame 106a, a switching gear 106e meshing with the short rack 106d, an extension head swing arm 106f fixedly connected to the switching gear 106e, a first positioning plate 106g hinged to the extension head swing arm 106f, a second positioning plate 106h disposed on one side of the first positioning plate 106g, and a second positioning plate 106h connected to the first positioning plate 106a. The active shaft 106i is hinged to the two positioning plates 106h, the delay gear 106j is fixedly connected to one end of the active shaft 106i, the double-extended head swing arm 106k is movably connected to the active shaft 106i and disposed outside the outer extended head swing arm 106f, the inner extended head swing arm 106l is fixedly connected to the end of the active shaft 106i and disposed outside the double extended head swing arm 106k, the long rack 106m meshes with the top of the delay gear 106j, and the first moving rod 106n and the second moving rod 106o are respectively disposed at the top two ends of the long rack 106m.

[0048] Preferably, the power supply component 107 includes a conductive piece 107a and a power supply 107b connected to the conductive piece 107a. The two sets of conductive pieces 107a, the first connecting piece 106b and the second connecting piece 106c, as well as the first contact piece 105c and the second contact piece 105d are all made of conductive materials.

[0049] It should be noted that two sets of limiting support grooves are respectively provided on one side of the housing component 104 to facilitate the entry and exit of the long rack 106m and the short rack 106d.

[0050] In use, staff can install additional equipment as needed. In this embodiment, the oxygen concentrator 102f is connected to a set of power supply components 107 via the first power line 108, and the air pump 102g is connected to the same set of power supply components 107 via the second power line 109. By unlocking the connecting piece 105, the first power line 108 and the second power line 109 are simultaneously fixed inside the housing 104. Then, pulling the tensioning wire to unlock the connecting piece 105 unlocks the delay switching piece 106 and connects the power. By adjusting the delay switching piece 106, a reasonable working time can be controlled and the switching can be cyclical.

[0051] The overall usage process is divided into four stages: wiring and fixing, connection and locking, delay switching, and emergency disconnection. The entire operation requires only one pull of the L-shaped spacer plate 105f to the insertion rod 105f-2 for fixation, followed by moving the first moving rod 106n to contact one side of the L-shaped spacer plate 105f and then moving it back, repeating this process. It is simple and convenient, reducing learning and operation time. The L-shaped spacer plate 105f serves as a distance indicator.

[0052] During the wiring and fixing stage, the workers insert the first power line 108 and the second power line 109 through the plug-in port on one side of the housing 104 and make the power terminals of the two sets of lines contact the first power contact piece 105c and the second power contact piece 105d respectively. Then, the workers pull the L-shaped spacer plate 105f to move it a certain distance along the longitudinal groove 104a. When the L-shaped spacer plate 105f moves, its bottom moving block 105g drives the two sets of telescopic rods 105h on both sides to move. The arc-shaped end of the arc-head tensioning block 105i on one side of the telescopic rod 105h contacts and presses against the arc-shaped end of the arc-head hollow driven plate 105e, causing the telescopic rod 105h to be gradually stretched and the arc-head tensioning block 105i and friction pad 105j to gradually clamp the two sets of lines. When the inner horizontal surface of the arc-head tensioning block 105i contacts the outer horizontal surface of the arc-head hollow driven plate 105e, the two sets of telescopic rods 105h extend to their maximum. The two sets of arc-head tensioning blocks 105i simultaneously clamp and fix the first energized line 108 and the second energized line 109, and the friction pad 105j prevents the lines from detaching. The arc-head tensioning block 105i is limited by the outer side of the arc-head hollow driven plate 105e, making the line connection tighter. When clamped, the extended end of the telescopic rod 105h enters the central space of the hollow driven plate 105e and, after contacting the inner wall of the hollow driven plate 105e, can drive the hollow driven plate 105e to move accordingly.

[0053] During the connection and locking phase, the workers continue to pull the L-shaped spacer plate 105f on the basis of the above, so that it moves a certain distance along the longitudinal groove 104a. At this time, the L-shaped spacer plate 105f can drive the bearing plate 105a to move as a whole and make the spring 105b stretched and have a tendency to rebound.

[0054] It should be noted that the tensioning unlocking connector 105 also includes an extension push plate 1051 connected to one end of the tensioning unlocking connector 105, and a double-headed limiting insert plate 1052 connected to one side of the extension push plate 1051.

[0055] When the insertion hole 105f-1 of the L-shaped spacer plate 105f is pulled to the insertion rod 105f-2, the position of the L-shaped spacer plate 105f can be fixed by the insertion rod to achieve self-locking. When the L-shaped spacer plate 105f is fixed, it represents the maximum distance that the entire support plate 105a can move. At this time, the first electrical contact piece 105c and the second electrical contact piece 105d on both sides of the support plate 105a are in contact with the first electrical contact piece 106b and the second electrical contact piece 106c, respectively. The first electrical contact piece 105c and the first electrical contact piece 106b are connected to a set of power supply components 107, which powers the oxygen generator 102f. During the movement of the support plate 105a, the extended push plate 1051 and the double-headed limiting insert plate 1052 will move, eventually causing the double-headed limiting insert plate 1052 to release the lock on the first moving rod 106n and the second moving rod 106o, allowing the delay switching component 106 to be adjusted, thus preventing the delay switching component 106 from shifting and failing when not in use and stored.

[0056] During the delayed switching phase, based on the above, the operator only needs to maintain attention and manually move the first motion lever 106n back and forth, or a reciprocating cylinder can be used for control, facilitating unmanned operation. When the first motion lever 106n is pushed close to the L-shaped spacer plate 105f, the long rack 106m moves towards the outer end of the housing 104, and the delay gear 106j meshing with its bottom rotates, causing the inner extension head swing arm 106l at the outermost end of the drive shaft 106i to rotate clockwise. The double extension head swing arm 106k, without the support of the inner extension head swing arm 106l, swings to the bottom until the inner extension head swing arm 106l rotates one revolution and then contacts the double extension head swing arm 106k again, causing the double extension head swing arm 106k to rotate accordingly, until the double extension head swing arm 106k rotates to contact the outer extension head swing arm 106f. This process constitutes the delayed operation. During this period, the short rack 106d remains stationary, keeping the L-shaped offset frame 106a stationary as well. The oxygen generator 102f remains powered on, thus controlling the reasonable working time. When the first moving rod 106n continues to move, it causes the double-extended head swing arm 106k to drive the outer-extended head swing arm 106f to rotate. The switching gear 106e begins to rotate, causing the short rack 106d to move and the L-shaped offset frame 106a to move. The first connecting piece 106b disengages from the first contact piece 105c, and the second connecting piece 106c connects to the second contact piece 105d and another set of power supply components 107. The air pump 102g begins to be powered on, realizing the switching of the working equipment. Then, simply resetting the first moving rod 106n and repeating the reverse process allows for switching again while ensuring a reasonable working time.

[0057] During the emergency cut-off phase, when it is necessary to quickly disconnect the power to the equipment, simply reset the first moving rod 106n, then pull out the plug rod of the plug rod 105f-2 to unlock the L-shaped spacer plate 105f. The tensioning unlocking connector 105 will spring back under the action of the spring 105b and completely disconnect the power.

[0058] In the control area 101c, staff maintain constant contact with and cyclically adjust the delay switching component 106 to ensure focus and avoid oversight. The delay switching component 106 ensures that each set of equipment must operate for a certain period before rapid switching can occur, facilitating efficient control of operating time. The overall operation requires only the mechanical control of the reciprocating linear motion of the first motion lever 106n, significantly reducing operational difficulty and allowing staff more time for timely data recording and analysis. Furthermore, by installing a cylinder at the first motion lever 106n to control its movement, the operating states of the oxygen generator 102f and air pump 102g can be cyclically switched during operation, further saving time. Staff only need to record data, and the system can adapt to multiple cyclic tests, achieving unmanned operation.

[0059] In summary, the overall operation of the reaction assembly can be controlled simply by connecting the control components, eliminating the need for complex and redundant operations. Operating the delay switching mechanism allows operators to focus their attention and effectively manage reaction time. The simplified operation of different devices and streamlined procedures facilitate automated maintenance of power supply time, automatic power switching, and simultaneous power cut-off of multiple devices. The tightening and unlocking connector quickly improves the efficiency of temporary equipment wiring connections, reduces operational hazards, facilitates easy disassembly and installation, and ensures secure wiring connections.
