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.

I have calculated 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 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........
