NOx Pollutant Formation in Turbulent Coal Systems
In Chapter 11 we introduced the concept and problems associated with chemical reactions in turbulent flows. We noted that among the most important questions in current combustion research are those regarding the interactions between the turbulent fluid mechanics and the chemical reactions. The apparent random fluctuations in the turbulent mixing of the reactants and products dramatically influences mean chemical kinetic rates that have reaction time scales on the order of the turbulent time scale or less. We saw that essentially all homogeneous gas combustion lies in this critical area, including the combustion of methane and higher-order hydrocarbon constituents of natural gas.
