Propane is burned in a furnace according to the following chemical reaction. C3H8+5O2→3CO2+4H2O Propane is fed at 1.0 mol/sec at 15 [C]. Air is used to provide oxygen for the process and the air stream is also at 15 [C]. Air is 21mol% O2 and the balance N2. If a mixture of gas and air contains more gas than is needed for ideal combustion, then it is referred to as a rich burn. If a mixture of gas and air contains less gas than is needed for ideal combustion, then it is referred to as a lean burn. Assume the outlet temperature is 175 [C] and make a plot of heat removed vs. the ratio of air flow rate to propane flow rate. Begin your plot with 20% excess propane (rich) and end with 100% excess oxygen. Assume the limiting reactant is completely consumed. Use at least 7 data points in your curve. Is it a good idea to feed excess oxygen? Why or why not?

Question
Propane is burned in a furnace according to the following chemical reaction.
C3H8+5O2→3CO2+4H2O
Propane is fed at 1.0 mol/sec at 15 [C]. Air is used to provide oxygen for the process and the air stream is also at 15 [C]. Air is 21mol% O2 and the balance N2. If a mixture of gas and air contains more gas than is needed for ideal combustion, then it is referred to as a rich burn. If a mixture of gas and air contains less gas than is needed for ideal combustion, then it is referred to as a lean burn. Assume the outlet temperature is 175 [C] and make a plot of heat removed vs. the ratio of air flow rate to propane flow rate. Begin your plot with 20% excess propane (rich) and end with 100% excess oxygen. Assume the limiting reactant is completely consumed. Use at least 7 data points in your curve. Is it a good idea to feed excess oxygen? Why or why not?
