Product Details
Main features
2) Hot air temperature: 80-800 degree C (adjustable)
3) Heat output: 600,000-12,000,000 kcal/hour;
4) Temperature control accuracy: +/- 15 degree C
5) Clean hot air is available by using tubular heat exchanger
Working principle
The air-cooled reciprocating grate is inclined stair-like grate of which each stair is removable. When biomass fuel is fed onto the top stair via the feeding hopper, it pushes the fuel down the length of the grate through distict drying,gasification, combustion and burn-out zones. The combustion air is blown into the combustion chamber from the grate bottom through the holes in each grate bar. The ash is automatically discharged off at the end of grate into an ash conveying system. After heated, the hot air (800-1000 ℃) is discharged by the exhaust fan for drying or heating process. Tubular type heat exchanger can be installed after the furnace to get clean hot air.
Technical advantages:
chips, bark, sawdust, forest waste, agriculture waste, rice husk etc. with low heat value and high ash content.
a. Drying zone: 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 600 mm. Less heat loss and complete combustion can guarantee 90% heat efficiency.
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.Grate drive motors are stepless speed regulating type.
8) Safety measures: exhaust fan is equipped to create negative pressure burning condition. Ash removing port is water sealed. The negative pressure and sealed burning chamber can make sure operation safety as well as cooling the grate.
