ABSTRACT: Russia's energy policy for the coming years provides for greater use of coal fuel, combined with the introduction of non-waste technologies of its combustion. Russia has taken to burn coal with ash content of various indicators, including those of high. The question of efficient use of coal in thermal power plants (TPP) of Russia by his deep preparation for burning is considered in this article. One way to solve of this problem is the construction of modern coal preparation factory directly or near the power plant. The criteria of efficiency of coal combustion are systematized. The modern methods of mineral raw materials enrichment used in the mining, metallurgical and chemical industries are considered. The parameters of coal preparation equipment offered in the Russian market by manufacturers from different countries are investigated. The systematic analysis of production processes in the TPP by functional modeling techniques based on IDEF0 diagrams and hierarchies analysis of T. Saaty is performed, allowing to prove the correctness of the proposed solution of the problem of coal enrichment in TPP prior to combustion and to provide an option of the technological chain of operations performed. The technical and economic effect after object modernization is defined. Coal deep preparation for burning, including the introduction of coal preparation factory on TPP, will create the environmentally friendly technology of fuel and energy coal-fired complex.
