Ex Balance the following reactions (assume complete combustion): (a) Hydrogen and oxygen with 20% excess oxygen; (b) Methane in theoretical air; (c) Methane burning with 95% theoretical air; (d) A mixture of 1 kmol methane and 2 kmol hydrogen (by mole) burning wtth 5 kmol of oxygen and 5 kmol of nitrogen.

The solution illustrates how to use the combustion TESTapps for balancing simple pre-defined reactions.

image of combustoin chamber Ex Determine (a) the adiabatic flame temperature of methane (CH4) burning with theoretical amount of air (inlet conditions 100 kPa, 298 K). Assume variable specific heats. What-if scenario: What would be the adiabatic flame temperature if the air supplied were (b) 90% (rich mixture) or (c) 110% (lean combustion) theoretical air? (Ans: 2329 K; 2307 K; 2191 K)
