Biomass fuel combustion stove without dust discharged from fire port and combustion method thereof

Abstract

The invention discloses a biomass fuel combustion stove without dust discharged from a fire port and a combustion method thereof. The stove comprises a stove base, a stove body and a stove surface; the stove body is arranged on the stove base, the stove surface is arranged at the top of the stove body, a middle sleeve, an inner stove chamber and a combustion chamber are arranged in the stove body,the inner stove chamber is arranged inside the middle sleeve, and a fuel gas channel allowing the gas flow to pass through is formed between the inner stove chamber and the middle sleeve; the combustion chamber is arranged at the middle upper part of the stove body and is located in the fuel gas channel between the inner stove chamber and the middle sleeve, a smoke discharging channel allowing the smoke to pass through is formed between the middle sleeve and the stove body, a smoke outlet and a fuel filling port are further formed in the stove body, the fuel filling port communicates with thecombustion chamber, and the smoke outlet is formed in the middle lower part of the stove body and communicates with the smoke discharging channel; and an air inlet is further formed in the stove body, and the air inlet communicates with the combustion chamber through an air pipe. By adopting the combustion stove and the combustion method, the structure is simple, the use is convenient, no dust isdischarged from the fire port of the combustion stove after combustion, and the stove and the method are suitable for being vigorously popularized and used.

Description

technical field [0001] The invention relates to the technical field of biomass fuel combustion, in particular to a biomass fuel combustion stove with dust-free discharge from a crater and a combustion method thereof. Background technique [0002] With the depletion of petrochemical energy and the increasingly serious environmental hazards caused by combustion, clean coal utilization technology and renewable clean biomass energy utilization have been widely concerned. To this end, my country has introduced relevant policies and increased investment in scientific research to promote the clean utilization of coal and expand the scale of biomass energy utilization. In the world's energy consumption, biomass energy accounts for about 15%, and it can account for more than 60% in underdeveloped areas. More than 90% of the living energy of about 2.5 billion people in the world is biomass energy. The use of biomass energy can not only realize the carbon cycle and reduce the emissio...

AI Technical Summary

Problems solved by technology

[0004] At present, the combustion furnace using biomass pellet fuel, because the junction of the top of the furnace and the heating body is generally open or equipped with a chimney, the heat absorbed by the heating body is only about 25% of the heat generated by the fuel, and the remaining 75% of the heat is passed through. The open opening or the chimney emits in the air, and at the same time, a large amount of dust is brought out, the heat utilization rate is low, and resources are wasted

Secondly, when the biomass pellet fuel is burned, the incompletely burned organic matter forms smoke and is discharged into the air, which is likely to cause air pollution
