Description

Technical Field

[0001] This utility model relates to the field of burners, and in particular to a boiler combustion structure. Background Technology

[0002] The demand for wear-resistant materials and mechanical structures in modern industry is increasing. Boiler burners, as key components of power plant thermal energy systems, play a crucial role in industrial production. The boiler burner bluff body is a device used in boiler burners, primarily to improve combustion efficiency and stability. Current burner structures have the following drawbacks: the cast stone plate is subjected to long-term impact and quarrying from large slag particles, leading to wear failure of the cast stone's anti-wear properties, making repair difficult and costly; and the surrounding wall panels suffer from numerous leakage defects after slag wear. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a boiler combustion structure in which a stainless steel grid is provided on the inner wall of the distribution chamber. The slag particles can adhere to the stainless steel grid more easily to form a wear-resistant layer, which can improve the wear resistance of the distribution chamber, prevent leakage, and the wear resistance becomes better with use.

[0007] A secondary diversion device is provided below the primary diversion device;

[0008] The side wall of the distribution chamber is connected to an outlet pipe.

[0009] This solution employs a primary and secondary diversion device, which can better create a local recirculation zone for the combustion medium, promote the mixing of the combustion medium and air, improve combustion efficiency, and enhance the stability of flame combustion. Furthermore, a stainless steel grid is installed on the inner wall of the distribution chamber, allowing slag particles to adhere more easily to the stainless steel grid, forming a wear-resistant layer. This improves the wear resistance of the distribution chamber, prevents leakage, and the wear resistance improves with use.

[0010] Preferably, the primary diversion device includes several diversion strips arranged in parallel in the air, with a diversion angle provided on the windward side of each diversion strip. This enables preliminary diversion.

[0011] Preferably, the diverter bar is made of angle steel. This results in lower cost and greater durability.

[0012] Preferably, the secondary diversion device is a suspended grid plate, which allows for more refined diversion.

[0013] Preferably, the grating is made of stainless steel, which makes it more durable.

[0014] Preferably, a plurality of hanging rods are fixed downward at the top of the distribution chamber, a crossbar is provided in the middle of the hanging rods, the end of the diversion strip is fixed to the crossbar, and the grid plate is fixed to the lower end of the hanging rods.

[0015] It makes it easier to fix the diversion strips and grating plates and maintain their relative distance in order to divert the combustion medium.

[0016] Preferably, the lower end of the hanging rod is provided with a hook, and the edge of the grating plate is hung on the hook. This facilitates the fixing of the grating plate.

[0017] Preferably, the side walls of the distribution chamber are made of stainless steel for greater durability.

[0018] Preferably, the abrasion-resistant plate is made of stainless steel grating, which is more durable.

[0019] Preferably, the outlet pipe is connected below the secondary diversion device, so that the diverted combustion medium flows downward and contacts the stainless steel grille at the bottom.

[0020] The beneficial effects of this utility model are:

[0021] Stainless steel grating is installed on the inner wall of the distribution chamber, which allows slag particles to adhere more easily to the stainless steel grating, forming a wear-resistant layer. This improves the wear resistance of the distribution chamber, prevents leakage, and the wear resistance improves with use. Attached Figure Description

[0025] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0026] Example

[0027] like Figure 1 As shown, a boiler combustion structure includes a distribution chamber 1, a primary flow divider 4, and a secondary flow divider 5;

[0028] The side walls of the distribution chamber 1 are made of 304 stainless steel with a diameter of 10mm, making it more durable. The inner wall of the distribution chamber 1 is covered with a stainless steel grating plate 9, and the wear-resistant plate is also made of stainless steel grating plate 9, further enhancing durability.

[0029] The top of the distribution chamber 1 is connected downward to the inlet pipe 2;

[0030] The primary diversion device 4 is provided below the inlet pipe 2;

[0031] A secondary diversion device is provided below the primary diversion device 4;

[0032] The side wall of the distribution chamber 1 is connected to an outlet pipe 3.

[0033] This scheme uses a primary diversion device 4 and a secondary diversion device, which can better form a local recirculation zone for the combustion medium, promote the mixing of the combustion medium and air, improve combustion efficiency, and improve the stability of flame combustion. In addition, a stainless steel grid is installed on the inner wall of the distribution chamber 1, which allows slag particles to adhere more easily to the stainless steel grid and form a wear-resistant layer, which can improve the wear resistance of the distribution chamber 1, prevent leakage, and improve wear resistance with use.

[0034] The primary diversion device 4 includes several diversion strips arranged in parallel in the air, with a diversion angle on the windward side of each strip. This allows for initial diversion. The diversion strips are made of ∠80*8 dovetail wear-resistant ceramic angle steel, resulting in lower cost and greater durability.

[0035] The secondary diversion device is a suspended 30*30 stainless steel grating plate 9. This allows for more refined diversion. The grating plate is made of stainless steel, making it more durable.

[0036] The welding points of the primary diversion device 4 and the secondary diversion device to the horizontal bar or hanging rod 6 are located on the leeward side to effectively prevent the welding points from being washed away by the medium and thus lose their effectiveness.

[0037] The top of the distribution chamber 1 is fixed with several hanging rods 6, and a crossbar 7 is provided in the middle of the hanging rod 6. The end of the diversion strip is fixed to the crossbar 7, and the grid plate is fixed to the lower end of the hanging rod 6.

[0038] It makes it easier to fix the diversion strips and grating plates and maintain their relative distance in order to divert the combustion medium.

[0039] The lower end of the hanging rod 6 is provided with a hook 8, and the edge of the grating plate is hung on the hook 8. This facilitates the fixing of the grating plate.

[0040] The outlet pipe 3 is connected to the lower part of the secondary diversion device so that the diverted combustion medium flows downward and contacts the stainless steel grid at the bottom.

[0041] The beneficial effects of this utility model are:

[0042] A stainless steel grid is installed on the inner wall of the distribution chamber 1. The slag particles can adhere to the stainless steel grid more easily to form a wear-resistant layer, which can improve the wear resistance of the distribution chamber 1, prevent leakage, and the wear resistance will get better with use.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
