An LP gas (Liquified Petroleum) is composed of 90% C4H10 (Butane) and 10% C3H6 (Propane) at 298 K and combusts with air at the same temperature. The volumetric analysis of the combustion products, at 1 bar, on a dry basis is: 6% CO2, 0.25% CO, 11.65% O2 and 82.1% N2.

1).- Combustion reaction balance 2).- Air-fuel ratio (AF) on a mass basis 3).- Percentage of theoretical air used 4).- Stoichiometric combustion gas temperature 5).- Higher and Lower Heating Value of the Fuel USE UP TO 4 DECIMALS FOR CALCULATIONS
