The equilibrium consideration of combustion, as presented in Chapter 1, leaves many of the critical questions regarding combustion processes unanswered. Primary among these questions is that of the rate of the combustion process. Some of the most vexing problems of air pollution arising from combustion processes are those resulting from the failure to obtain equilibrium conditions. Concentration levels of hydrocarbons, carbon monoxide, and nitric oxide emitted from combustors characteristically exceed the predicted equilibrium values for the exit conditions. The rate of the combustion process determines not only the efficiency of the combustor, but, additionally, the characteristics of the combustion products.
