Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a gas duct adjustment structure for a biomass burner. Background Technology

[0002] A biomass burner is a device used to convert biomass materials such as wood, straw, wood chips, and pellets into heat energy. It can be used for heating, power generation, or other industrial processes to meet heat energy needs. Biomass burners typically employ combustion or gasification technology to burn or gasify elements such as carbon, hydrogen, and oxygen in biomass materials, releasing heat energy and producing combustion exhaust gases. Biomass burners are widely used to replace traditional fossil fuels in order to reduce environmental impact and promote the use of renewable energy.

[0003] In actual use, the influence of air causes incomplete combustion of biomass, resulting in low biomass utilization efficiency. This is because air is supplied from the ash layer, the highest combustion temperature is in the combustion layer, and the accumulation of ash generated by combustion hinders the participation of air. The combustion space above the reduction layer has insufficient temperature, resulting in incomplete combustion and the formation of dense smoke. This causes a large amount of calorific value to be lost during the combustion of biomass fuel, which greatly wastes energy and makes it inconvenient to use. Utility Model Content

Figures 1-2 and Figure 4 The emission mechanism includes a collection box 3, which collects the ash after the biomass fuel is burned.

[0032] The discharge mechanism also includes a partition plate 301. The surface of the partition plate 301 is fixedly connected to the inner wall of the outer shell 1. The partition plate 301 is located above the collection box 3. The surface of the partition plate 301 is provided with a slag discharge groove 302. Two slag discharge grooves 302 are symmetrically distributed with the width axis of the partition plate 301 as the center. The bottom of the collection box 3 is fixedly connected with a movable pulley 303. Multiple movable pulleys 303 are symmetrically distributed with respect to the bottom of the collection box 3.

[0036] By setting up a combustion mechanism and an emission mechanism, the combustion mechanism uses the combustion chamber 2 to tumble and burn the biomass fuel, and the emission mechanism uses the collection chamber 3 to collect the ash after the biomass fuel is burned. This solves the technical problem that existing biomass burners produce a large amount of ash during the combustion process, which hinders air from participating in the combustion process and prevents complete combustion of biomass fuel.

[0037] Working principle:

[0038] Before use, open the sealing plate 207 on the surface of the outer shell 1, and feed the biomass fuel into the combustion chamber 2 from above the feeding platform 208 through the feeding pipe 203. After feeding, close the sealing plate 207, and ignite the biomass fuel through the igniter 204 at the bottom of the combustion chamber 2. This drives the tilting motor 201 on the surface of the outer shell 1. The tilting motor 201 drives the combustion chamber 2 to rotate along the axis of the rotating shaft 202 at one end of the combustion chamber 2. The ash produced after the biomass fuel is burned is discharged from the combustion chamber 2 through the ash discharge hole 205 on the surface of the combustion chamber 2 and accumulates on the surface of the partition plate 301. The air intake fan 209 below the feeding platform blows outside air into the interior of the outer shell 1 through the air intake pipe 210. The air intake volume of the air intake pipe 210 is controlled by the three-way valve 212 on the surface of the air intake pipe 210, and the gas flow meter 211 on the surface of the air intake pipe 210 monitors and adjusts the flow. The air intake is increased by the air blown in through the air intake pipe 210 and enters the combustion chamber 2 through the air intake hole 206 at the top of the combustion chamber 2, which improves the combustion efficiency of biomass fuel. After circulating inside the combustion chamber 2, the air carries the flue gas generated by combustion into the exhaust pipe 213 set above the outer shell 1 and is discharged from the exhaust hole 214 on the surface of the exhaust pipe 213. The ash generated by the combustion of biomass fuel accumulates on the surface of the partition plate 301. The moving motor 307 set on the surface of the outer shell 1 drives the moving screw 305 to rotate, which drives the ash cleaning plate 304 threaded on the surface of the moving screw 305 to move along the axis of the guide rod 306. The ash cleaning plate 304 pushes the ash accumulated on the surface of the partition plate 301 from the ash discharge groove 302 on the surface of the partition plate 301 into the collection box 3 below for collection. Multiple moving pulleys 303 set below the collection box 3 facilitate the movement and cleaning of the collection box 3.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
