Direct- Fired Hot Air Furnace

Direct-fired hot air furnace is directly use flue gas, it is a kind of heating arrangement which use coal, firewood and shell as it’s flue, put the flue into primary zone to obtain heat. Spinning form secondary combustion chamber absorb the fire and gas from primary zone under the function of negative pressure and the gas will revolve at the surface of wall to strengthen combustion. The unique high-temperature dust removal device installed in secondary combustion chamber separate the most of dust from exhaust gas. The clean air from jacket will dilute the hot air and make the temperature at desired value to direct output and application
