INFLUENCE OF NONEQUILIBRIUM PROCESSES OF RADIATION COOLING OF COMBUSTION PRODUCTS ON THE CONTENT OF NITROGEN OXIDES IN ATMOSPHERIC EMISSIONS

Abstract

A method was developed for the experimental and theoretical determination of nonequilibrium radiation cooling of a flame based on experimental data on its temperature and chemical composition of fuel. We obtained information about the influence of nonequilibrium radiation processes on radiation cooling of an optically thin flame. The influence of nonequilibrium processes on the formation of nitrogen oxides (NOx) is analyzed. It is shown that nonequilibrium radiation decreases the concentration of NOx, while the mechanisms of nonequilibrium radiation cooling can be used for controlling and optimizing the furnace process.
