8. Coal fired in a furnace analyzes 57.1%C, 8% ash, 1.4% N and 0.77% S. The Residue contains 24.5% C and 75.5% ash. Orsat analysis of the stack gas shows 11.21% CO, , 1.57% CO, 7.45% 02 and 79.77% N2 . Neglect N and S in the coal in the combustion calculations. Calculate: a) Complete ultimate analysis of coal (5.87% H, 26.86%O) (40.6%) b) % excess O2
