Effect the dissociation of H2O and CO2 on adiabatic flame temperature

Abstract EN

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
