2.Principle of Operation:
The Direct Coal (Biomass)-Fired Hot Air Furnace consist of BHL Coal (Biomass) burner, hot flue gas purity room and air feeding room. The range of heat output is from 50x104 kcal / h to 2000x104 kcal / h and the range of temperature output is from 100ºC to 1200 ºC.
Raw Coal (Bituminous Coal) (Biomass) is fed into coal scuttle through coal (Biomass) feeder, and then delivered into combustion chamber by the chain grate stoker. With the air of combustion blower, the coal (Biomass) burned and generated high temperature flue gas with dust. The hot flue gas with dust burned again and the dust fused, polymerization and deposition in the purity room, certain amount of fresh air is mixed into the cleaned hot flue gas (about 1000 ºC,drawing from the purity room) to adjust the temperature of the hot flue gas in the air feeding room. And then the degree temperature hot flue gas flows into the various large-scale drying systems (such as fluidized bed, flash dryer, spray tower, rotating drum dryer, drying room, etc.). The fluctuation range of continuous heating air temperature is about ± 5 ºC. The cinder is discharged by the auto-deslagging.
3. Advantages for Gas Fired Hot Air Furnace

1) It can burn multi-coal (Biomass).
2) High combustion efficiency, Thermal efficiency is more than 95%,
3) The output of the heat load is very stable. As to the mechanical combustion, it is simple to operate and easy to adjust;
4) The hot air is very clean and the dust content is from 30 to 120mg/Nm3.
5) The hot air temperature below 1200°C is easy to adjust. The fluctuation range of continuous hot air temperature is about ± 5 ºC.
6) Equipment durability, low operating costs, easy maintenance.
