Webb4 juli 2024 · We have, Theoretical air requirement = (11.6 X %C + 34.8 3 (%H2 - %O2/8) + 4.35 X %S)/100…Kg/kg of fuel Therefore, Th air requirement will be = (11.6 X 50 + 34.8 X (3.2 - 8.2/8) + 4.35 X 0.4)/100 = 6.57 kg of air/kg of coal. Given that,O2 in flue gas is 5% We have, Excess air = (O2%/ (21 - O2%)) X 100 = (5/ (21 - 8)) X3 100 = 38.5%
