Question
Transcribed Image Text:Assume that 3.75 kg/s of air, at 750k and 20
bars, enters the premix chamber of a combustor.
The target temperature inside the combustion
chamber is 1900K. The following cases are to be
analysed a) 100% Methane b) Blends of
Methane and Hydrogen, with 30%-50% and
80% H2 by volume c) 100% Hydrogen For each
case assume that Nitric Oxide (NO) is present in
the products and is in equilibrium
Calculate
i. The mass flowrate of fuel required for each
case
ii. The resulting parts-per million of NO
produced for each case
