Direct Coal-fired Hot Air Furnace

 

Operating Preinciple 

MBZ direct coal-fired hot air furnace consists of MBL coal fired machine, high temperature urifying room and air mixing room.

 

Bituminous coal (soft coal) is fed into coal hopper through coal feeder. The coal at a certain height is delivered into buring hearth of coal burner by chanin grate. Combustion fan sends air into burner, hot gas produced by burning coal erupts from fire outlet of coal burner and enters in high temperature purifying room.The cinder is discharged from the other side of coal burner by cinder conveyor.
 

Hot gas enters in high temperature purifying room and begins secondary combustion. The dust in the gas impact, aggregate and subside in the prifying room. Clean hot air from purifying room at about 1000 deg. C then mixes into a certain amount of fresh air, the mixture at the wanted temperature flows in to dryer(such as spray tower, rotary dryer, oven, drying house, flash dryer, fluidized bed etc.)to dry material. Temperature of hot air can be adjustable according to the demand. When hot air is supplied continuously, its temperature fluctuates within±5 deg.C.

Advantages of Hot Air Furnace

1.Heat efficiency>95%;

2.Operate simply, adjust easily;

3.High security, there is no danger of explosion;

4.Durable, low operating cost, easy maintenance;

5.Hot air is very clean, dust content:25-1320mg/Nm3;

6.Sufficient combustion, there is no balck smoke, good operation conditions;

7.All the hot air flows into dryer, there is no increased outlet during production process;

8.Hot air temperature below 900 deg.C can be adjustable easily. When hot air is supplied cntinuously, its temperature fluctuates within±5 deg.C.
