The quantity of the steam produced is indicated in tons of water evaporated to steam per hour. Most coal-fired power station boilers use pulverized coal, and many of the Percentage heat loss due to evaporation of water formed due to H2 in fuel A 10% blow down in a 15 kg/cm2 boiler results in 3% efficiency loss.

OIL FIRED BOILER CONVERSION TO PULVERIZED COAL | Project
End date 31 March 1985 This is to be achieved by use of a new type of pulverized coal combustor generating a After two weeks for calibration and control adjustment the boiler arrived at its design specification of 40 T/h steam production at 74 Bar-500 C. During tests, the boiler load was 35-36 T/h (88-90 % capacity).
