Chain grate coal-fired boiler It can withstand a high temperature of about 1300 degrees to about 1600 degrees. In addition, the length of the grate is between 5 and 15 meters, which increases the burning time of the fuel and can fully absorb the heat released from the coal.
The corner tube chain grate coal-fired boiler does not need to add bed material, and the heavier fuel is burned on the grate, so the fly ash share is small. The corner tube boiler is arranged in a multi-flue, which significantly reduces the original dust concentration of the boiler.
126.96.36.199 STOKER GRATE BURNING RATE. Burning rate is the higher heating value (in Btu) of the type of coal used multiplied by the number of pounds of coal burned per hour to obtain the rated boiler capacity; divided by the total active burning area, in square feet, of the stoker grate. The maximum values shown are based on the assumption that
For chain grate boiler, which can burn many kinds of coal, the combustion efficiency of which is relate to the quality of environment and resources consumption rate.
