Coal having the following analysis on a dry basis contains 3.9% moisture and is burned with excess air: 65.4% C, 5.3% H, 18.5% O, 1.1% N, 0.60% S, and 9.1% ash. The Orsat analysis of the combustion gases give the following result 13.0% (CO₂ + SO₂), 0.76% CO, 6.17% O2, 0.87% H₂2, and 79.2% N₂. Calculate: a) mass of coal fired/ 100 kmol of dry flue gas b) mole flue gas/mol dry air c) moles of water vapor in the flue gas per 100 kg coal if the air supplied is dry d) % excess air
