High purity direct coal-fired hot air furnace consists of coal
burner, high-temperature purifying room, air mixing room and
control system. Features: clean, low cost, operate simply. The heat
capacity of single high purity direct coal-fired hot air furnace
ranges from 0.5-200 million kcal per hour. Maximum output
temperature is 1000 ℃. To dry the products, furnace can attach to
spray tower, rotary kiln, fluidized bed, air dryer, drying house,
1.Sufficient combustion, hot air without black smoke, good
operating conditions; Meet the demand of environmental protection,
No secondary pollution
2.Clean hot air, dust content is between 30 and 120 mg/Nm3
4.Temperature of hot air under 1000℃ can be adjusted easily. When
hot air is supplied continuously, its temperature fluctuates
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
