    2016-6-29 · Gaseous propane of 88 kg/hr is burned in a boiler with 10% excess air to produce 1200 kg/hr of steam at 0.1 MPa and 150oC. The percent conversion of the propane is ; of the fuel burned, 90% reacts to form CO2 and the balance to form CO. The temperature of combustion air, fuel and water entering the boiler is assumed at 25oC.
