A factory uses superheated steam (P = 15 bar, T = 250 oC) for heating purposes of 20,000 tons/month. Steam is made in a boiler-furnace using 2 (two) types of fuel, namely coal fuel (LHV = 5500 kcal/kg) and heavy fuel oil (137129 Btu/ft3, density = 0.98 m3/kg) Question: a. How much coal fuel is needed to produce steam with the above specifications if the overall efficiency of the system (boiler-furnace = 75%)! b. How much heavy fuel oil is needed to produce steam with the above specifications (boiler-furnace = 75%)! answer every month..
