I have done a very simple combustion of a fuel mixture using the following CH4, O2, H2, H2O, CO, CO2, N2 and C2H6 as the fuel+ air with 21% o2. using ANSYS-FLUENT-Eddy Dissipation Model
I have calculated STOICHIOMETRICALLY the amount of O2 required for complete combustion (above fuel mixture composition given so calculated accordingly) and supplied it, so temperature and every thing is coming fine but when excess amount of O2 is supplied the the temperature increases further consuming all the EXCESS O2 eg if i supply 20 % excess O2 it should reflect in exhaust unconsumed rt but its not happening, rather a huge temperature increase is happening compared to the stoichiometric one.
Kindly help me out guys , why is this happening ???
THANKS A LOT IN ADVANCE........

Thanks a lot for that but my question was y excess o2 is getting consumed. How can oxygen be consumed above stoichiometry in a reaction
Since Eddy-dissipation model of ANSYS FLUENT: Reaction rates are assumed to be controlled by the turbulence, it is recommended to check the settings of your calculation; and I believe that you may find some hints regarding the solution of your problem if you go through the USER manual ANSYS FLUENT (section of the Eddy -dissipation model).
