Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a burner structure of a gas burner. Background Art

[0002] The burner's fire port refers to the area in the burner where gas and fuel mix and burn. This area is usually an opening. The mixed gas and fuel through this opening react chemically with the outside air to generate flames and combustion heat energy.

[0003] Existing burner ports mostly adopt: 1. a perforated plate structure; 2. a pore structure formed by stacking a plurality of groups of corrugated plates; 3. a slit structure.

[0004] However, the orifice-type burner has a small aperture (≤3mm), a large number of holes (>1000), and a thick steel plate (≥10mm). It is difficult to process and easy to deform. In addition, the orifice plate has poor cooling effect and a high risk of tempering.

[0005] The corrugated plate structure fire port is composed of multiple layers of corrugated plates stacked together. Due to the small size of the corrugations, it has high requirements for the stacking, pressing and assembly process, and is difficult to assemble. It is easy to have problems such as offset and misalignment, which leads to uneven gas distribution and uneven flame lengths, affecting the combustion effect.

[0006] The slot-type burner is composed of multiple pipes arranged in parallel, and the gas passes through the gaps between the pipes. The flame produced by its structure is shorter, but the flame is continuous and longer horizontally. The flame is in the shape of a narrow strip and is erratic. The flame stability is poor and the combustion effect is poor. Summary of the invention

[0007] The utility model aims to solve one of the technical problems in the above-mentioned technology at least to a certain extent.

[0008] To achieve the above-mentioned purpose, the first aspect of the utility model proposes a gas burner flame structure, comprising: a plurality of columns arranged closely in sequence to form a flame wall; a cavity is provided inside the column and is open at both ends, and a cooling medium enters from an opening at one end of the column and is discharged from an opening at the other end after passing through the cavity; a flame port is provided between two adjacent columns, and gas is ejected from one side of the flame port for combustion; the flame port comprises two holes, and the two holes are respectively provided on opposite sides of two adjacent columns; wherein the two opposite holes are independent of each other or partially connected.

[0009] In addition, the gas burner burner structure proposed in the utility model may also have the following additional technical features:

[0010] As a further description of the above technical solution: there are multiple fire ports between every two adjacent columnar bodies, and they are opened in sequence along the length direction of the columnar bodies.

[0011] As a further description of the above technical solution: the columnar body is a polygonal column structure.

[0012] As a further description of the above technical solution: the cooling medium is air or water or liquid nitrogen or liquid hydrogen.

[0013] As a further description of the above technical solution: the hole grooves are cut and formed.

[0014] The gas burner burner structure according to the utility model has the following advantages:

[0015] 1. It is composed of multiple hollow columns, which are closely arranged in a row to form a fire mouth wall. There is no structure such as perforated plate or corrugated plate, and the assembly is simple and convenient.

[0016] 2. The burner is a hole-groove structure cut and formed on the tube wall of two adjacent columns, which is easy to process and easy to achieve mass production.

[0017] 3. The burner is arranged between two adjacent columns. The holes and slots in each burner are independent of each other or partially connected, which blocks the horizontal series connection ability of the flame root and makes the flame more stable.

[0018] 4. The burner is cut and formed on the tube wall of two adjacent columns, which increases the connection area between the burner wall and the flame, which can effectively reduce the flame temperature and reduce the risk of flashback. At the same time, each burner is independent of each other, dividing the flame into many small flames, further reducing the risk of flashback.

[0019] 5. It is composed of multiple hollow columns. The cooling medium enters from one end of the hollow column and is led out from the other end, thereby cooling the burner wall and reducing the flame temperature.

[0020] Additional aspects and advantages of the present invention will be given in part in the following description and in part will become apparent from the following description or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The gas burner burner structure of the utility model embodiment is described below with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 2As shown, the burner structure of the gas burner of the embodiment of the utility model may include a plurality of columns 110 closely arranged in sequence to form a burner wall 100 for isolating the flame and high-temperature smoke from the gas.

[0038] It should be noted that the plurality of columns 110 are arranged in a single row, and two adjacent columns 110 are tightly fitted together.

[0039] A fire port 200 is provided between two adjacent columns 110, and gas is ejected from one side of the fire port 200 for combustion. A cavity 101 is provided inside the column 110 and is open at both ends. The cooling medium enters from an opening at one end of the column 110, passes through the cavity 101, and is discharged from an opening at the other end. The introduction of the cooling medium can reduce the temperature of the flame at the fire port wall 100 and the fire port 200.

[0040] It should be noted that there are a plurality of the burners 200 between every two adjacent columnar bodies 110 , and the burners 200 are opened sequentially along the length direction of the columnar bodies 110 .

[0041] The burner 200 includes two holes 201 , and the two holes 201 are respectively opened on opposite sides of two adjacent columns 110 , wherein the two opposite holes 201 are independent of each other or partially connected.

[0042] It should be noted that the hole groove 201 is cut and formed, that is, it is cut and opened on the basis of the existing columnar body 110 to reduce its processing difficulty and facilitate mass production.

[0043] In one embodiment of the present utility model, Figure 2 As shown, the opposite sides of the two holes 201 in the burner 200 are connected, and the flame is ejected from between the two holes 201 to improve the flow of the fuel gas.

[0044] In another embodiment of the present utility model, Figure 3 As shown, the two holes 201 in the burner 200 are independent of each other and are staggered to divide the flame into smaller flames and improve the stability of flame combustion.

[0045] In another embodiment of the present utility model, Figure 4 As shown, the hole slots 201 in the burner 200 are multiple slots connected in series, and two hole slots 201 are interconnected to improve the fluidity of the gas.

[0046] In another embodiment of the present utility model, Figure 5 As shown, the hole groove 201 in the burner 200 is a long strip-shaped groove opened along the length direction of the columnar body 110, and the two hole grooves 201 are interconnected to reduce the lateral continuity of the flame.

[0047] Specifically, when the relevant staff discharges the gas through the burner 200 and ignites it, the relevant staff can pass the cooling medium into the columnar body 110 along the cavity 101 to reduce the temperature of the burner wall 100 and the flame. When the flame is ejected and burns through the burner 200, due to the independent design of the burners 200, the flame can be divided, reducing the risk of backfire.

[0048] In one embodiment of the present invention, the columnar body 110 is a polygonal column structure, such as Figures 6 to 9 As shown, structures such as triangular tubes, rectangular tubes, hexagonal prisms, etc. can be used to meet the installation requirements of fire mouth walls 100 of different shapes. The cavity 101 can be a cylindrical cavity structure to improve the stability of the cooling medium flowing in the cavity 101. The cavity 101 can also be a polygonal prism structure similar to the columnar body 110 to increase the volume of the cavity 101 and improve the flow of the cooling medium in the cavity 101.

[0049] In one embodiment of the present invention, the cooling medium is air or water or liquid nitrogen or liquid hydrogen.

[0050] It should be noted that the cooling medium may also be other flowing media having a cooling effect.

[0051] As a possible situation, when the cooling medium is air, the outside air can be introduced into the cavity 101 through a fan or a blower to achieve cooling.

[0052] As another possible situation, when the cooling medium is liquid, the columnar body 110 can be cooled by a circulation system, which includes a cooling pipe, a water pump and a coolant tank.

[0053] Among them, the cooling pipe connects multiple columns 110 and is connected to the coolant tank through a water pump. Water or liquid nitrogen or liquid hydrogen or other liquid cooling media are poured into the coolant tank. Through the suction of the water test pump, the cooling medium flows between the cooling pipe and the multiple columns 110 to achieve cooling.

[0054] In summary, the gas burner flame port structure according to the embodiment of the utility model has many advantages such as low processing difficulty, easy assembly and more stable flame combustion.
