20t/h coal-fired boiler calculation of coal consumption -- ZBG

The coal consumption of 20t/h coal-fired boiler is about 2700 kg/h. This is assuming that the efficiency of a 20-ton boiler is 80%. If the thermal efficiency is increased, the coal consumption of the boiler will be greatly reduced.There will be a formula for the calculation of coal consumption for coal-fired boilers.
