The design of Bio-Pellet Fuel Hot Air Stove adopts the countercurrent combustion method, that is, the direction of the combustion flame is opposite to the direction of the feed material. This combustion method makes the hot smoke flow pass the surface of the wet fuel, which promotes the drying of the fuel and the transportation of water vapor, so that Fuel is prone to fire.

At the same time, the secondary air is injected tangentially along the circular furnace wall at a high speed, and the cyclone ensures good mixing of flue gas and secondary air, prolonging the residence time of unburned carbon particles in the furnace. The Bio-Pellet Fuel Hot Air Stove manufacturer tells you to set up a secondary combustion chamber at the rear of the furnace to burn unburned carbon particles and combustible gas in the furnace, reducing the black smoke generated by combustion caused by high temperature and oxygen deficiency.
The manufacturer of Bio-Pellet Fuel Hot Air Stove tells you that the high-temperature flue gas after combustion passes through the settling chamber to further capture the dust and reduce the dust content in the flue gas. In terms of air distribution, since the rear of the hot blast stove is equipped with an induced draft fan, the combustion method of the furnace is slightly negative pressure combustion. The primary air is sucked through the slag chamber under the grate, and the secondary air is injected tangentially along the air ducts on both sides through the high-pressure blower. hearth. The manufacturer of Bio-Pellet Fuel Hot Air Stove tells you that this not only effectively controls the strong wind to blow away the fly ash and unburned carbon particles on the grate, but also ensures a large amount of air necessary for the combustion of biomass fuel.
