Effect the Dissociation of H2O and CO2 on Adiabatic Flame Temperature

Abstract

In this study a theoretical model was accredited to show the effect of dissociation phenomenon on adiabatic flame temperature. CH₄, C₂H₆, C₃H₈ and C₄H₁₀ as gases fuel, global reaction and a thermodynamics analysis were dependent in this model to analysis a combustion to evaluated adiabatic flame temperature. Four cases are studied no dissociation, only H₂O dissociation, only CO₂ dissociation and both H₂O and CO₂ dissociation together. The results show that with dissociation adiabatic flame temperature will be decreased and the bigger effect on adiabatic flame temperature when only CO₂ dissociation. Also the effect range of equivalence ratio on dissociation phenomenon was from 0.9 to 1.1
