Blast furnace gas is a by-product in converting iron ore to metallic iron using metallurgical coke. A blast furnace gas extracted from a blast furnace is composed of 30% N2, 32% CO, 12% CO2, 8% H₂O and 18% H2. This fuel gas contains high carbon monoxide content and low heating value but can be used as fuel within the steel works and sometimes combined with natural gas to sustain combustion. If 100 mol of the fuel gas is burned with 250 mol of air, what is the percent excess air supplied?
