THE NITROGEN OXIDE CONCENTRATION DEPENDENCE ON HEAT LOSSES WITH EXIT SMOKE GASES OF HEAT-GENERATING PLANTS

Problem statement. The most significant heat losses are losses associated with exit gases. It is these losses that determine the scale of heat emissions into the plant air with fuel combustion products and reduce the environmental safety of the plant. Many of the derived methods for reducing the nitrogen oxide emission associated with gas purification systems provide a high degree of smoke gas purification, but these methods are based on the use of various chemicals, which sharply reduces their environmental and operational characteristics.Results. The suggested method of simultaneous purification and recycling of gaseous emissions of heat-generating plants differs profitably from the existing ones. Its application will improve tech-nical and economic and also environmental characteristics of heat-generating plants and will make the characteristics of the energy enterprise a closer match to those of waste-free, environmentally-friendly and profitable enterprises.Conclusions. The obtained results confirm the fact that reduction of heat losses with exit gases re-sults in a reduction of nitrogen oxide emissions. Therefore, an increase in environmental safety of a boiler unit can be achieved in tandem with one in heat efficiency.
