High clean direct biomass fired hot air furnace consists of coal
burner, high-temperature purifying room, air mixing room and control system.
Features: clean, low cost and simple operation. The heat capacity of single high
purity direct coal-fired hot air furnace ranges from 500,000-2,000,000 KCal/
hour. Maximum output temperature is 1000 ℃. To dry the products, furnace can
attach to spray tower, rotary kiln, fluidized bed, air dryer, drying house,
oven, etc.
Advantages
1. Full combustion, no black smoke hot air, clean operating environment; The emission of SO2 is zero and the environmental protection is up to the standard.
2. Clean hot air, dust content is between
30 to 120 mg/Nm³
3. Heat efficiency
>95％
4. Temperature of hot air under 1000℃ can be adjusted easily. When hot
air is supplied continuously, it's temperature fluctuates within ±5℃
5. Operate simply, adjust easily
6. High security without any danger of explosion
7. Durable, low operating cost, easy maintenance
8. All the hot air flows into dryer; there is no increased outlet
during production process
