2020/4/9 · In boiler operation, excess air represents a heat loss. Besides, how do you calculate air needed for combustion? Therefore the quantity of oxygen required for combustion of 1 kg of the fuel is: (2.66C + 8H + S) kg. ∴ Oxygen required from air for the complete combustion of fuel will be (2.66C + 8H + S – O) which can be written as 2.66C + 8
