1621 | Thermodynamics
(a) the equilibrium composition of the product gases and (b) the rate of heat transfer from the combustion chamber. Is it realistic to disregard the presence of NO in the product gases?
Answers: (a) 3CO2, 7.5O2, 4H2O, 47N2, (b) 5066 kJ/min Carbon monoxide is burned with 100 percent excess air during a steady-flow process at a pressure of 1 atm. At what temperature will 97 percent of CO burn to CO2? Assume the equilibrium mixture consists of CO2, CO, O2, and N2. Answer: 2276 K 1622 Reconsider Prob. 1621. Using EES (or other) software, study the effect of varying the percent excess air during the steady-flow process from 0 to 200 percent on the temperature at which 97 percent of CO burns into CO2. Plot the temperature against the percent excess air, and discuss the results. C3H8 25C AIR 12C CO Combust...
