Description

Technical Field

[0001] The utility model relates to the field of pellet stoves, in particular to an easy-to-clean biomass pellet stove. Background Art

[0002] Biomass pellets are columnar combustion materials made from materials such as straw, rice husks, and corn cobs. They have the advantages of high calorific value, cleanliness, and no harmful substances such as sulfur dioxide when burned. In addition, biomass pellets produce very little ash after burning, and the ashes after burning can also be used as organic fertilizer. Therefore, biomass pellet combustion furnaces using biomass pellets as raw materials have emerged.

[0003] Biomass pellet combustion stoves generate a lot of heat when burning. The flames of existing pellet stoves directly heat the heat sink during combustion, and then discharge the heat through the fan. Long-term heating will cause the heat sink to deform after continuous heating and cooling, which will reduce the life of the heat sink. In addition, the ashes of the pellet stove are not convenient to clean after burning. Utility Model Content
