Propane is burned in a furnace using air as an oxygen source. For this exercise will will assume that air is 20% O2 and 80% N2. The flow rate of the air provides a 60% fractional excess of oxygen which allows for complete consumption of the propane. The inlet feed of air and propane to the furnace is at a temperature of 45 [C]. Assume a propane flow rate of 1 mol/min and answer the following questions. A. If the temperature of the outlet stream is 300 [], how much heat is removed from the furnace? B. If 1600 kJ/min of heat is removed from the furnace, what is the temperature of the outlet stream?
