“…The use of model has made it possible to authentically predict emissions of gaseous nitrogen oxides in case of reconstruction to the low-temperature vortex method of boilers of low (БКЗ-75 Southern thermal plant of Rubtsovsk town) [12], medium (БКЗ-210 of Kirovskaya CHPP-4 and БКЗ-220 of Novomoskovskaya regional hydro-electric power plant (RHEPP) [13][14][15][16][17][18][19][20] and high (П-49 Nazarovskaya RHEPP) [21,22] capacity. The acquired calculation data have been used as the basis for environmental substantiation of reconstruction projects and proven a possibility of fulfilling applicable standards for the level of emissions of nitrogen oxides to environment in case of burning of a wide range of fuels: peat, brown and black coals of different grades.…”

Abstract.One of the effective tools of solving engineering problems is the mathematical simulation of newly built and reconstructed industrial equipment. A necessity of solving identical problems fully belongs to generating equipment of thermal power plants too, which makes the use of methods of mathematic simulation quite a promising one in the course of designing power-generating units. The work presents the results of simulation and subsequent incorporation of the method of low-temperature vortex fossil solid-fuel combustion. Based on the developed algorithms and calculation program the assessment of environmental indicators of reconstructed boiler equipment has been carried out and compliance with environmental standards with respect to the level of emissions of gaseous pollutants into environment confirmed. The incorporation of the method being considered into power-generating production has made it possible to reduce emissions of gaseous nitrogen oxides during combustion of coals of different types by 30%.

The paper presents the results of studies of the effect of a two-light screen on the formation of nitrogen oxides in the combustion chamber of a medium-power steam boiler. A methodology, a mathematical model and a computational program have been developed that allow one to assess the degree of reduction in nitrogen oxide emissions during the combustion of solid fuel when installing a two-light screen in the furnace. Computational studies have confirmed that the presence of a two-light screen makes it possible to reduce the generation of nitrogen oxides by an amount from 10 to 12 % in comparison with the option of a boiler furnace without a two-light screen.

The thermal power plants (TPP) make a basis of power-generation industry of the majority of countries. The global growth of power consumption and the policy of energy-saving demand to increase the efficiency of plants operation, which is, among others, determined by the technical level of steam-generating units. The up-to-date digital technologies make it possible to assess the efficiency of boiler furnace operation at the stage of boiler unit designing, its reconstruction or retrofitting and upgrading. Developed in the article are the algorithm, mathematic model and computer program of calculating diffusion-kinetic process of combustion of D-grade Donetsk coal in the coal-dust flame of boiler Е-230-14,0-520. The assigned tasks have been solved by using theoretical methods of analysis, the capabilities of devices of computer-aided calculations have utilized for visualization of results. The considered digital approach to solving technical tasks makes it possible to meet the current and future challenges.
