[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, a combustion device for a gas-fired heating boiler includes:

[0024] Boiler body 1, with a base 101 at the bottom and an exhaust pipe 102 connected to the surface of the boiler body 1;

[0025] Combustion structure 2, which is disposed inside the boiler body 1, is used to heat the water stored inside the boiler body 1;

[0026] The smoke exhaust structure 3 is disposed on the surface of the boiler body 1, and the smoke exhaust structure 3 is used to reduce the impact of smoke and dust on the environment after combustion.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the combustion structure 2 includes a connecting shell 202 disposed inside the boiler body 1. The interior of the connecting shell 202 forms a combustion chamber. One end of the connecting shell 202 extends through the boiler body 1 and is provided with a gas supply pipe 201, which is used to supply gas to the interior of the combustion chamber.

[0028] The inner wall of the connecting shell 202 is fixedly connected to the mounting shell 203. One side of the mounting shell 203 is connected to the air supply pipe 201, and the other side of the mounting shell 203 is connected to a uniformly distributed connecting pipe 204. The surface of the connecting pipe 204 is provided with uniformly distributed nozzles 205.

[0029] The surface of the connecting shell 202 is fixedly connected with annularly distributed heat-conducting fins 206, which are located inside the boiler body 1.

[0030] The surface of the connecting shell 202 is connected to a flue pipe 207, which is spirally arranged, and the other end of the flue pipe 207 passes through the heat-conducting fin 206 and the boiler body 1 in sequence and extends to the outside of the boiler body 1.

[0031] An igniter is installed inside the combustion chamber to ignite the gas injected into the combustion chamber.

[0032] Gas is injected into the mounting shell 203 through the gas supply pipe 201. The gas injected into the mounting shell 203 is evenly introduced into the connecting pipe 204. During this process, it is discharged into the combustion chamber through the nozzle 205 for combustion inside the combustion chamber. The heat generated during combustion is dissipated into the boiler body 1 through the connecting shell 202 to heat the water stored inside the boiler body 1. Since the connecting shell 202 is located inside the boiler body 1, the heat generated during combustion in the combustion chamber can be evenly distributed inside the boiler body 1, reducing heat loss and improving heating effect. At the same time, the heat-conducting fins 206 can increase the contact area between heat and water and improve heating efficiency. The flue pipe 207 is used to discharge the flue gas generated during combustion. The flue gas carries some heat. The spirally arranged flue pipe 207 can exchange heat with the water inside the boiler during the flow of flue gas, effectively utilizing this waste heat, so that the heat generated by combustion can be fully applied to the water stored inside the boiler body 1.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the flue gas structure 3 includes a fixed shell 301 fixedly connected to the surface of the boiler body 1, one end of the flue gas pipe 207 is connected to the interior of the fixed shell 301, and the surface of the fixed shell 301 is connected to the discharge pipe 307.

[0034] The fixed shell 301 is provided with a collection shell 302 inside. The surface of the collection shell 302 is provided with uniformly distributed through holes 306. The collection shell 302 is provided with a filter element 303 inside. The filter element 303 is an activated carbon material component.

[0035] The upper end of the collecting shell 302 extends through the fixing shell 301 and is provided with a connecting plate 304. The surface of the connecting plate 304 is provided with bolts 305, and the lower end of the bolts 305 extends through the connecting plate 304 and is threadedly connected to the inner wall of the fixing shell 301.

[0036] The flue gas discharged through the exhaust pipe 207 can enter the interior of the fixed shell 301 and be guided into the collection shell 302 by the through hole 306. The filter element 303 of the activated carbon material component can filter the harmful substances in the flue gas. The filtered flue gas is discharged through the exhaust pipe 307. The staff only needs to periodically remove the bolt 305 and take off the connecting plate 304 to replace the filter element 303 inside the collection shell 302, which reduces the pollution caused to the environment by the direct discharge of flue gas.

[0037] In use, this invention injects gas into the mounting shell 203 through the gas supply pipe 201. The gas injected into the mounting shell 203 is then evenly introduced into the connecting pipe 204. During this process, the gas is discharged into the combustion chamber through the nozzle 205 for combustion inside the combustion chamber. The heat generated during combustion is dissipated into the boiler body 1 through the connecting shell 202 to heat the water stored inside the boiler body 1. The flue pipe 207 is designed to discharge the flue gas generated during combustion. The flue gas carries some heat, and the spirally designed flue pipe 207 can exchange heat with the water inside the boiler during the flow of flue gas, effectively utilizing this waste heat. This allows the heat generated by combustion to fully act on the water stored inside the boiler body 1. Furthermore, under the action of the flue gas structure 3, the filter element 303 of the activated carbon material component can filter harmful substances in the flue gas. The filtered flue gas is discharged through the discharge pipe 307. Operators only need to periodically disassemble the bolts 305, remove the connecting plate 304, and replace the filter element 303 inside the collection shell 302, reducing the pollution caused by direct discharge of flue gas to the environment.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
