The processes of burning a gaseous fuel in the furnace of the DE-10/14 steam water-tube boiler have been investigated numerically. The temperature and velocity distributions of the gases in the furnace space of the boiler, as well as the concentrations of combustion components have been determined. It has been shown that placing a secondary radiator along the horizontal axis of the burner in the furnace space of the boiler promotes the formation of a uniform temperature field along the length of the furnace and a decrease in the temperature in its space, and the reverse flow of combustion products to the combustion front provides a decrease in the concentration of nitrogen oxides to 123–125 mg/m3 at the furnace outlet.
