Abstract

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.

Highlights

  • The goal of the energy policy of country according to the energy strategy of Russia for the period up to 2030 is the maximum efficient use of natural energy resources and potential of the energy sector for steady economic growth, increase of quality of life of the country’s population and contribution to strengthening its foreign-economic solutions.The thermal power plants (TPP) make a basis of power-generation industry of Russia with the share in the structure of the installed power of the industry as of 2017 equal to 58.6 %

  • The share of TPP operated on coal equals 27.5 %

  • The efficiency of TPP operation depends to a great extent on the technical level of the main equipment, to which the steam boilers belong too

Summary

Introduction

The goal of the energy policy of country according to the energy strategy of Russia for the period up to 2030 is the maximum efficient use of natural energy resources and potential of the energy sector for steady economic growth, increase of quality of life of the country’s population and contribution to strengthening its foreign-economic solutions. The insufficient consideration of the problem of fuel combustion process in polifraction flame of the steam power-generating boiler at the stage of designing can bring about in practice an excessive consumption of fuel, for instance, caused by mechanical underburning and, as a result, it entails the price growth for electric energy for consumers. The burning process will be determined by complex physical and chemical phenomena [1, 2] related to fuel burning in the furnace chamber of steam boiler. Taking into account the process stage character, the burning of coal particles of polifraction fuel moving in the flow of gases has been calculated, the paths of movement thereof in the furnace have been acquired;.
