Technical Field

[0002] The biomass pellet furnace is a combustion equipment that uses biomass pellets as fuel. It has the advantages of environmental protection, high efficiency and energy saving, simple operation and cleanliness. The biomass pellets are transported into the combustion chamber for semi-gasification combustion. Subsequently, the biomass pellets are cracked at high temperature to produce combustible gases such as hydrogen, methane, and carbon monoxide, so that the biomass pellets are fully burned. Generally, the transportation of biomass pellets from the silo to the combustion chamber is achieved by a screw dragon or other automatic feeding equipment. However, as the biomass pellet furnace continues to burn, the flame in the combustion chamber backflows into the silo along the transportation route of the biomass pellets, affecting production safety. On the other hand, biomass pellets usually contain impurities. These impurities cause the biomass pellets to sinter into blocks when burning in the combustion chamber, that is, a harder slag shell is generated on the surface of the biomass pellets, which hinders the full combustion of the biomass pellets.
