abstract: The main methods of reducing nitrogen oxides concentration in flue gases during the boiler plants operation are considered and analyzed.It was shown that simplified recirculation scheme with the flue gases supply into the inlet of the blower fan makes it possible to reduce emissions of nitrogen oxides at relatively low capital and operating costs.The aim of the work is to evaluate the impact of flue gases recirculation into the furnace on the technical, economic and ecological characteristics of
