A lignite containing 43,5% C, 6.5% H2, 42.3% O2, 0.5% N2, and 7.2% ash (by weight) is burnt in a furnace with 30% excess air containing 0.015kg water vapor/kg BDA. Calculate a. The flue gas analysis on the assumption that 85% of the C is burnt to CO2, 10% to CO and the remaining portion is discharged with ash. b. Moles of ambient air entering the system
