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?

Answer rating: 100% (QA)

SOLUTION A To calculate the heat removed from the furnace we need to know the enthalpy of combustion of propane and the amount of propane consumed The enthalpy of combustion of propane is approximatel... View the full answer
