Propane is burned in a furnace sccording to the following chemical reaction. C3HA+5O2+3CO2+4H2O Propane is fed at 1.0mol/sec at 15 [C]. Air is used to provide oxygen for the process and the air stream is also at 15 [C]. Air is 21mol8O2 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 bum If a mixture of gas and air contains less gas than is needed for ideal combustion, then it is referied to as a lean buin. Assume the outlet temperature is 175 ICI and make a plot of heat removed vs the rato 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 teed excess oxygen? Why or why not
