Direct Boiler Efficiency = Heat output / Heat Input X 100. Or. Direct Boiler Efficiency = Q X (h2 h1) / (q X GCV) X 100. Here Q = Qty of steam generated. h2 = Enthalpy of steam at the output of the boiler. h1 = Enthalpy of feed water. Heat Input = q X GCV. q = Fuel Qty.

Learn MoreCalculate the combustion-air mass required to burn the 20 gallons of No. 6 fuel oil above. Since the air-fuel stoichiometric ratio is 14.4 pounds of air per pound of fuel the boiler's burner would need 20 gallons x 7.95 lb/gal for No. 6 fuel oil or 2289 pounds of air to burn the oil. This would in turn yield a total flow of 2628.1 lb/hr of steam.
