When energy fuels prices in 2009 jumped up but electrical energy tariffs were kept constant, electric generation companies stabilized economics of their production with the help of coal quality increasing and the part of natural gas decreasing. It was reached without specific fuel expenditure increasing. Coal quality increasing was realized due to progressive quality-price scale application, to making coal quality control in the power plant arrival more sharp, to decreasing the difference between coal quality in the power plant arrival and of used for combustion.

The paper deals with the problem of reliable definition of heating value, volatile yield and sulfur content in coal organic matter and develops the methods of calculation evaluation of these parameters for coals with real ash content. The amendments due to mineral matter thermal decomposition are accounted. 8 power coals of Donetsk and Lvov-Volyn basins are studied having volatile yield from1 to 40% in frameworks of ash content from 10 to 40%. Calculations based on parameters defined more precisely differ from laboratory results not more than allowed laboratory test error value.

The use of carbon-containing material from ash dumps at anthracite thermal power plants to extend the fuel base of thermal power plants in Ukraine is validated. The resources in ash dumps at anthracite thermal power plants and the distribution of unburnt carbon in them are described, results of test firing agglomerate mixtures of material from ash dumps with sludge in a circulating fluidized bed are presented, and recommendations are given for its preparation as fuel.
