Biomass combustion furnace

Abstract

The invention relates to combustion furnaces and provides a biomass combustion furnace which is suitable for heating heat transfer oil furnaces, superheated steam furnaces, air heating furnaces, water heaters and the like. Through the biomass combustion furnace, biomass can be enabled to be combusted sufficiently, utilization rate of biomass combustion is increased, combustion ash can be removed timely during combustion, and pollution due to the fact that air flow is discharged into air is avoided. The biomass combustion furnace comprises a combustion base, a combustion chamber arranged on the combustion base and a flange arranged on the combustion chamber, the combustion base comprises a combustion base body, a feed device and a second air blower, an ash storage box is arranged at one end of the combustion base body, an air inlet box is arranged at the other end of the combustion base body, a combustion tank which is communicated with the ash storage box and the air inlet box is arranged on the upper portion of the combustion base body, air vents are formed in the combustion tank, the combustion tank, the bottom surface and the lateral surface of the combustion base body, the ash storage box and the air inlet box form a cavity jointly, an air inlet communicated with the air inlet box is formed in the lateral surface, connected with the air inlet box, of the cavity, the feed device is arranged outside the combustion base body and passes through the air inlet box to be led to the combustion groove, and the second air blower is communicated with the air inlet box.

Description

technical field [0001] The invention relates to a combustion stove, in particular to a biomass combustion stove. Background technique [0002] In recent years, the development, recycling and production of biomass fuels have received unprecedented attention. The raw material of biomass fuel is mainly obtained from agricultural and forestry waste, which is inexhaustible. Through a series of deep processing, biomass particles or powder are usually produced, and the two are burned separately and converted into biomass energy to provide alternative energy for industry. , not only solves the problem of agricultural and forestry waste disposal, but also reduces the emission of CO2 and harmful gases to the atmosphere. [0003] In the existing biomass combustion equipment, biomass is usually burned in a combustion chamber first, and the heat energy generated by it enters the second chamber to heat the furnace body. Since the flue gas generated after biomass combustion can be further...

Problems solved by technology

As the combustion progresses, the ashes and unburned materials produced by the fuel combustion will block the air intake holes on the grate to a certain extent and affect the air supply combustion, so the ashes produced by the material combustion need to be used during the combustion process. It is discharged in time, but the cleaning must be carried out after the fuel is burned, so once the air intake hole is blocked, the furnace will stop working and clean up to delay time; The holes are only distributed at the bottom of the combustion chamber, and there is a certa
