[0002] With the development and progress of society, people pay more and more attention to the environment. Traditional hot air furnaces have been gradually replaced by biomass hot air furnaces. The so-called biomass hot air furnace uses biomass as fuel and produces less harmful gases than traditional fuels. The traditional biomass hot air furnace is mainly composed of a furnace body, a furnace, a blower, an exhaust port, a chimney and a combustion chamber. The furnace is located in the furnace body, and a furnace door is provided at the lower part of the furnace body. The combustion chamber is located at the lower part of the furnace. The biomass material burns in the combustion chamber. The blower blows natural wind into the furnace to add to the furnace. The natural wind mixes with the high-temperature flue gas burning in the furnace to form high-temperature wind, which is then discharged through the exhaust port. The flue gas generated by burning biomass is discharged from the furnace body through the chimney.
