A fuel known to contain methane and ethane is burned in a furnace with air which is saturated with water vapor, the pressure of which is 12.08 mm Hg and for every mole of fuel burnt, 15.73 moles of wet air is supplied. The stack gas is found to contain incompletely burned carbon in the form of carbon monoxide and is found further that the ratio of the moles of CO2 to CO is 9:1. Also the vapor pressure of water in the flue gas is 118.47 mm Hg and that 17 moles of wet stack gas is produced per mole of fuel. Calculate:(Round everything to 4 decimal places and make a basis) a. ORSAT analysis of the flue gas b. Percent excess air

Question

A fuel known to contain methane and ethane is burned in a furnace with air which is
saturated with water vapor, the pressure of which is 12.08 mm Hg and for every mole of fuel burnt, 15.73 moles of wet air is supplied. The stack gas is found to contain incompletely burned carbon in the form of carbon monoxide and is found further that the ratio of the moles of CO2 to CO is 9:1. Also the vapor pressure of water in the flue gas is 118.47 mm Hg and that 17 moles of wet stack gas is produced per mole of fuel. Calculate:(Round everything to 4 decimal places and make a basis)
a. ORSAT analysis of the flue gas
b. Percent excess air
