TION 8 (Fuels and Combustion) A boiler is fired with a fuel having a mass composition: C = 86.1%, H2 = 3.9%, O2 = 1.4% and ash = 8.6%. Volumetric analysis of dry flue gases gives CO2 = 12.7%, CO = 1.4% O2 = 4.1% and N2 = 81.8%. Calculate: (a) The total amount of flue gas per kg of fuel fired. (b) The percentage of excess air supplied above the minimum quantity required fo complete combustion of fuel %3D %3D
