Theoretical air fuel ratio
Webb12 maj 2024 · Actual quantity of air supplied = (1 + Excess air %/100) X theoretical air = (1 + 20/100) X 2.9 = 3.48 kg of air/kg of fuel. Example-4: A flue gas has 10% of CO2 and theoretical calculated CO2 is 12%, then calculate percentage of the excess air. % of Excess air = ( (Theoretical CO2%/Actual CO2%) - 1)) X 100 = (12/10) - 1) X 100 = 20% Webb14 apr. 2024 · Theoretical air-to-fuel ratio is defined as the minimum amount of air and fuel needed to convert hydrocarbon fuel into carbon dioxide and water vapor. Even if we maintain a theoretical air in the real combustion process due to less contact time in the combustion chamber, the air and fuel mix is improper, which ends up in incomplete …
