Consider the combustion of jet fuel (C10H20, ?h0f = -247015 kJ/kmol) and air. Assume that the reactants enter the combustor at 298 K.
(a) Find the adiabatic flame temperature of stochiometric reaction.
(b) The answer in part 1) should well be above 1600 K, which is the current limit of turbine temperatures.So we need to lower the combustor flame temperature to 1600 K. We can do this by either raising ?or lowering ?. For fuel conservation requirements we choose to lower ? by raising the amount of air inthe reactants for the same amount of fuel. Determine the equivalence ratio required to keep the flametemperature at 1600 K.
