Basic Principle of Sawdust Burner:Through the feeding device, the raw materials enter the fuel bin, then blowing into sawdust burner by air fan, Through high-temperature cracking and suspended semi-gasification combustion, and then transfer the heat to the energy-using equipment. Using the principle of radiant heat and convection heat, three-stage of air distribution and oxygen increasing to make sawdust fully burned in the furnace and more than 95% of heat is transferred to energy-using equipment.
