Secondary Power Resources of the Fuel and Energy Complex in Ukraine

This article describes the types of secondary energy resources that occur during or as a result of mining or of technological processes at metallurgical, coke and chemical enterprises. The research of opportunities to use them directly at industrial enterprises, in case when an energy resource or the energy generated "is not a commodity" was carried out. To generate electricity from secondary sources, the use of diesel power plants and gas–turbine facilities was offered. The values of investments in the construction of thermal power plants (TPP) based on different types of secondary energy resources were calculated. Tentative capacities of power plants, which utilize the energy of secondary sources were also computed. The figures used for assessing the release and use of secondary energy resources were given. The necessity of using secondary sources of energy to reduce harmful effects on the environment was emphasized. Introduction. World coal production totals 2.025 billion tons per year (4033 mines). This results in nearly 6 bln tons of solid, liquid and gaseous waste being formed, which is about 3 tons per 1 ton of coal (including dump waste product of 2.5 tons). In underground coal mining, specific output of the rock hoisted onto the surface of the mine constitutes about 0.3 tons per 1 ton of coal. Actually combustible mass in the coal industry is only 20% of the rock mass. As follows, in order to preserve fossil fuel resources the number of which is steadily decreasing in the world and the use of which produces more harmful effect on the environment, one should try to use all their potential. The use of waste, or so–called secondary energy resources (SER), formed during the coal mining, will reduce the harmful effects on the environment and increase the energy potential of Ukraine. Research objective. Unprofitability of mines associated with the high cost of coal production, large overheads and a complex environmental situation in these regions are considered to be main problems of coal mining enterprises in Ukraine.
