2000Kg Coal Wood Fired Steam Boiler With Moving Grate Working
Safety
Introduction of moving garate wood fired steam boiler
1. The boiler is equipped with drum and induced draft fan to
mechanical ventilation, combustion equipment with compact dense
hole grate, especially suitable for biomass fuel combustion.
2. By manual feeding, the flame through the back wall to the
combustion chamber after the combustion, up into the airfoil flue,
and then through the front smoke box thread smoke tube, through the
economizer, air pre-heater, duster and induced draft fan to the
chimney and finally into the atmosphere.
Combustion Processe of 2 ton Industrial wood Fired Boiler
The fuel burning at the furnace through, the exhaust gas flow from
the boiler barrel bottom to the smoke window outlet on the Eight
character wall, then enter convection bank at the both wings, next
enter the thread smoke tube through the front smoke box, pass by
economizer, dust remover, and induced draft fan, finally discharged
to the atmosphere by chimney.

2. What is the height of chimney ?
The chimney is usually 30m, irrespective of the special
circumstances.
3. What are the heat-resistance temperature of grate and furnace ?
The heat resistance temperature of grate is related to the grate
material, the highest temperature could be as high as 1200℃, and
the lower temperature could be 700℃. The highest heat resistance
temperature of furnace could be about 1700℃~1800℃.
