Mass per mole of air
WebThe amount of combustion air is 2 moles of oxygen plus 2 x 3.76 moles of nitrogen, giving a total of 9.52 moles of air per mole of fuel. The air fuel (AF) ratio for the above combustion on a mass basis is: AF 17.19 kg air /kgfuel 1 16.04 9.52 28.97 That means 17.19 kgof air is used to burn each kilogram of methane.
