Description

Technical Field

[0001] This utility model relates to the field of biomass pellet combustion technology, and specifically to a biomass pellet combustion device. Background Technology

[0002] Biomass pellet fuel is the direct combustion of biomass energy, representing the processing and utilization of biomass. Direct combustion methods can be categorized into four types: stove combustion, boiler combustion, waste combustion, and solid fuel combustion. Fully utilizing biomass energy to replace energy sources such as coal reduces CO2 and SO2 emissions, which is beneficial to environmental protection.

[0003] Most existing biomass pellet combustion devices are unable to clean up during combustion, resulting in the accumulation of dust and biomass pellet residue. This leads to incomplete combustion of subsequent biomass pellets, increasing combustion costs and reducing combustion efficiency. Therefore, there is an urgent need to design a biomass pellet combustion device to solve these problems. Utility Model Content
