Abstract

A chemical reaction during which a fuel is oxidized and a large quantity of energy is released is called combustion. The oxidizer most often used in combustion process is air; since it is free and readily available. Any material that can be burned to release thermal energy is called a fuel. Most familiar fuels consist primarily of hydrogen and carbon. They are called hydrocarbon fuels and are denoted by the general formula, CnHm. In this paper, the thermodynamic properties and heat generation potential of octane fuel, under stoichiometric condition, was studied. The colorless and flammable fuel, when oxidized stoichiometrically, yielded a heat output, Qout, of 5,470,720 kJ/kmol; and an air-fuel ratio, AFR, of 15.14 Kgair/Kgfuel. A combustion between octane and air (in excess of theoretical air), gives an air-fuel ratio, AFR, of 24.22 Kgair/Kgfuel. AFR is the ratio of the mass of air to the mass of fuel for a combustion process. This ratio helps the engineer to predict how economical and feasible the combustion of fuel will be.
