A gas contains 80.0 wt% propane, 15.0 wt% -butane, and the balance water.
a. Write out the balanced stoichiometric equations for complete and incomplete combustion.
b. If 100 kg/h of this fuel is to be burned with 30% excess air, what is the required air feed rate (kmol/h)? Calculate the molar composition of the feed gas on both a wet and a dry basis and the ratio (mol H2O/mol dry gas).
c. If 100 kg/h of this fuel is to be burned with 30% excess air and all the fuel is consumed with 75% complete combustion for both fuels, calculate the molar composition of the outlet gas on both a wet and a dry basis and the ratio (mol H2O/mol dry gas).
