Аннотация: The results of experimental studies of preliminary thermal processing of pulverized solid fuel under conditions of a semi-industrial installation for the preparation and combustion of coal with a productivity of up to 150 kg/h are presented. The studies were conducted over a wide range of pre-processing temperatures from 300 to 900 °C, air excess from 0.2 to 0.9%, and the residence time of the carbon particles in the installation from 0.6 to 2.5 sec. The effect of preliminary thermal processing regimes on the reduction of nitrogen oxide emissions during the combustion of heat treatment products is shown experimentally. At a heat treatment temperature of 650- 800 °C, emissions of nitrogen oxides are reduced by 2-3 times compared to burning of the initial fuel. An interpretation of the mechanism of the effect of preliminary thermal processing of coal on the reduction of nitrogen oxide emissions is proposed. © 2020 Institute of Physics Publishing.
