4. A coal analyzing 65.4 % C, 5.3% H, 0.6% S, 1.1% N, 18.5% O, and 9.1% ash is burned so that all combustible is burnt out of the ash. The flue gas analyzes 13.00 % CO₂, 0.76% CO, 6.17% 0₂.0 0.87% H₂, and 79.20% N₂. All of the sulfur burns to SO₂, which is in cluded in the CO₂ in the gas analysis (.e., CO₂ + SO₂= 13.00%). Calculate: a Pounds of coal fired per 100 lb mol of dry flue gas as analyzed: b. Ratio of moles of total combustion gases to moles of dry air supplied; c. Total moles of water vapor in the stack gas per 100 lb of coal if the entering air d. Percent excess air. is dry;
