Combustion of Solid Fuel. A fuel analyzes 74.0 wt % C and 12.0% ash (inert). Air is added to burn the fuel, producing a due gas of 12.4% CO2, 1.2% CO, 5.7% O2, and 80.7% N2. Calculate the kg of fuel used for 100 kg mol of outlet ?ue gas and the kg mol of air used. (Hint: First calculate the mol O2 added in the air, using the fact that the N2 in the ?ue gas equals the N2 added in the air. Then make a carbon balance to obtain the total moles of C added.)
