Gaseous fuel composed of 65% carbon, 30% hydrogen and 5% oxygen saturated with water vapor is burned with 20% excess air. Air is supplied at 70°F, saturated with water vapor. Incomplete combustion has taken place on the burner and that analysis shows that the ratio of CO2 to CO in the stack gas is 3:1. Calculate:

a) the complete analysis of the wet stack gas,

b) the volume in ft3 of air supplied per lb mole fuel burned. The assume barometer is normal.

p: draw the given
