In a furnace, methane at 25°C is combusted with 20.% excess air, which also enters at 25°C. The feed rate of methane is 450 kmol/h, and the combustion gases exit the furnace at 300°C. The furnace gases can be considered ideal. Some of the heat from the furnace is used for a boiler, where liquid water entering at 25°C is converted to water at 10 bar and 250°C. d. Calculate the composition of the gas leaving the furnace. e. Calculate the rate of steam production in the boiler
