Calculate the adiabatic flame temperature for the following mixtures initially at 298 K: stoichiometric butane-air mixture, stoichiometric butane-oxygen mixture, 2.0% (by volume) of butane in air. Calculate without the restriction on the possible products using an online version of the CEA calculator developed by NASA and located athttp://www.grc.nasa.gov/WWW/CEAWeb/ceaHome.htm. Compare the results of the two calculations and explain possible differences.

the adiabatic flame temperature (theoretical maximum temperature) of black coal in air is over 2000oC. If the ambient temperature is 20oC then the theoretical maximum efficiency of a coal fired power station is approximately 87%. Why then is the efficiency of even the best coal fired power stations less than 50%.
