Abstract

With the decline in the supply of Donetsk anthracite and semi-anthracite as a result of fighting in the east of Ukraine, for the first time in the world it managed to solve scientific and practical problems and to organize producing of homogeneous mixture of anthracite with 27–32 % bituminous coal at Zmiev TPP fuel stock, as well as safe and effective mixture combustion in TP-100, TPP-210, TPP-210A boilers with performance characteristics and technical and economic indicators not different from those of the Donetsk semi-anthracite. For state-owned coal enterprises it gave additional volume of sales, and for thermal power plant it has significantly expanded fuel base, made it possible to reduce the night unloading unit loads of down to 65 % without oil or gas addition due to more stable ignition and combustion of coal mixture compared with anthracite.
