A furnace is burning natural gas (90% by mol methane and thebalance ethane) at 20 Celsius degree and 1 atm with 25% excess airat 150 Celsius degree and 1.1 atm. The product gases are at 600Celsius degree and 1 atm. 95% of each fuel gas forms CO2 while thebalance forms CO. a) What is the ratio of air supply volume to fuelvolume? b) What is the composition of the product gas mixture on amol% basis? c) What is the ratio of exhaust gas volume to fuelvolume?
