Working Principle

BHL-Z direct Coal (Biomass) Fired Hot Air Furnace consists of BHL coal burner, decontamination settling chamber of high temperature air and Air distribution chamber. Its output heat is 50~2000×104Kcal/h, output temperature is 100~1200℃.

Raw Coal (Bituminous Coal) is fed into coal scuttle through coal feeder, and then delivered into combustion chamber by the chain grate stoker. With the air of combustion blower, the coal 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 ℃,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 ℃. The cinder is discharged by the slag remover

 

Advantage

1) Wide adaptability of coal types.

2) Full combustion, high combustion efficiency, thermal efficiency>95%.

3) Stable output heat load, mechanical combustion, simple operation and very convenient adjustment.

4) The hot air has a high degree of cleanliness, with a dust content of 30~120mg/Nm³; no black smoke, and environmental protection standards.

5) The hot air temperature is easy to adjust, adjustable below 1200℃, and the continuous heating air temperature stability is ±5℃.

6) The equipment has strong durability, low operating cost and simple maintenance.

Note:
1.The calorific value calculated of coal (biomass) is counted with 5000 kcal / kg in the table.
2.Circulating cooling water can be also used for living water, fresh water should be supplemented immediately.
