Combustion Of Fuel Gas Calculator
This calculator determines the flue gas composition resulting from the combustion of a fuel gas with a given excess air. Additionally it calculates the lower heating value of the fuel gas and the air/fuel ratios. Air is assumed to be at 60 °F and composition entered should include moisture.
