Empirical Equations For Adiabatic Flame Temperatures For Some Fuel-Air Combustion Systems

Abstract

A new simple formula for calculating the adiabatic flame temperature of fuel/air mixtures has been developed. The formula is usable in a wide range of both fuel and reaction variables. Among the fuels considered for the formula are members of the paraffin, aromatic, olefin and alcohol families, and hydrogen and acetylene. The formula is functionally expressed in terms of the fuel/air ratio, the reaction pressure, the initial mixture temperature and the number of carbon atoms in the individual fuel. By using the formula, the adiabatic flame temperature for a designated fuel and reaction condition can be found within an accuracy of one percent.
