[0002] Biomass hot air furnace with high efficiency heat transfer is a device that uses biomass fuel for combustion, generates heat energy and converts it into hot air. This type of hot air furnace usually adopts advanced combustion technology and heat exchange technology to improve energy efficiency and reduce the impact on the environment. Biomass hot air furnace can be used in a variety of applications such as heating, drying, industrial heating, etc. Compared with traditional coal-fired hot air furnaces, biomass hot air furnaces are cleaner and more environmentally friendly, because the exhaust gas emissions generated by biomass combustion are relatively small, and biomass fuel is a renewable resource, which is conducive to reducing dependence on fossil fuels. The working principle of the biomass hot air furnace is to put the biomass fuel into the combustion chamber for combustion, and the generated heat energy is transferred to the air through the heat exchanger to form hot air and transport it to the area that needs to be heated.
