Automatic Hot Air Generator / Chemical Industry Hot Air Drying Furnace

Hot Air Drying Oven Technical advantages:

1) Flexibility for various kinds of fuels: Reciprocating grate can perfectly burn various kinds of fuels, such as coal, wood chips, bark, sawdust, forest waste, agriculture waste, rice husk etc. with low heat value and high ash content.

2) Suitable for fuels with high moisture content: The grate can be divided into Four zones:

a. Drying zone: for preheating and dispersing the fuel

b. Gasification zone : gasifying fuel surface for easy burning

C. Combustion zone: fuels completely combusted

c. Burn-out zone: ash discharging and collecting

3) Perfect and complete combustion: the reciprocation movement can perfectly disperse and turn over the fuels during combustion, so the combustion is perfect and complete.

4) Good insulation and high heat efficiency: the heat insulation layer is 750 mm which can make sure the surface temperature of furnace is about 40 °C. Less heat loss and complete combustion can guarantee the heat efficiency reach 90%.

5) Long life-span: the combustion chamber frame is made by high strength steel and lined by casting heat resistant cement and firebricks. The grate bar is made by heat resistant alloy steel. The normal life-span can reach 10 years.

6) Automatic operation: fuel feeding, ash discharging and grate moving are fully automatic.

7) Stable output temperature: Temperature control is achieved by accurately regulating the combustion air, grate movement and feeding speed. All the fans are equipped with inverters. Grate drive motors are stepless speed regulating type.
