2. A high sulfur fuel oil containing 75.2%C, 9.59% S and negligible N is burned in excess air to supply the heat necessary to calcine a stone consisting of 52.3% CaO, 2.5% MgO, 43.1% CO2 and 2.1% moisture. The operation of the kiln is such that the lime is incompletely burned and contains 6.2% CO2 . The average orsat analysis of the kiln gas shows 25.4% CO2, 1.9% CO, 0.5% SO2 , 5% O, and 67.2% N2 . Calculate: a) Complete ultimate analysis of the fuel (7.78% H, 7.43% O) b) Fuel ratio (6.57 kg lime/kg oil)
