Premixed Flames 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 Diffusion Flames A. If an engine burns 0.2 kg/s of liquid Diesel (C12H26), what flowrate of Methanol would be required to produce the same power? B. What are the environmental advantages of using methanol over Diesel? Please Show step and calculations.
