ME Board Problem Local coal with higher heating value of 5,500 kCal/kg is burned in a pulverized coal fired boiler with 25% excess air at the rate of 25.9 M.T. per hour when the steam generated is 220 M.T. per hour. This boiler is served by 2 forced-draft fans of equal capacity delivering the air at 305 mm of water to the furnace.
