Analysis of CH4 CombustionProblem with Fortran Program

Based on the thermodynamic properties of combustion process,methane combustion process in the adiabatic combustor was analysed by Fortran program. When the quantity of methane was definite, the effect of different amount of air used on the temperature, chemical composition, flow energy, heat transfer energy and irreversibility of the combustion process were investigated. It was found that two states had the same compositions, and xN2 and xO2 in these states would increase when the amount of air was over supplied into the combustion and no dissociation. Under the condition of dissociation the irreversibility was easily to occur.
