The relevance of the work is proved by considerable prospects (environmental, energy, economic and other) of using coal-water fuel as the primary fuel for boilers of different capacities. The aim of the research is to study the thermal and environmental performance of boiler in different regimes, providing both dry and liquid slag removal. Investigation of thermal characteristics involves an experimental study of temperature distributions in the boiler fur- nace for further construction of mathematical models of coal-water fuel combustion and search for optimal regime parameters. The methods include experimental studies of combustion of coal-water fuel, prepared on the basis of flotation product (cake) after enrichment of coal of grade K, using a pilot sample of the boiler unit. Experimental studies were carried out by various (thermocouples, pyrometer, gas analyzer) instruments with low measurement error. Results. Experimental data on temperature distributions in the boiler furnace were obtained for further modeling of coal-water fuel combustion; flue gas composition was measured for different operation regimes; boiler operation and data on the baseline characteristics of fuel were analyzed. Conclusions. The promising design of the boiler unit, which can work at dry and liquid slag removal, was studied. Primary the data were obtained for modeling heat and mass transfer processes at combustion of coal-water fuel, prepared on the basis of coal tailings. The results obtained on measuring the flue gas emissions indicate the prospects of using the coal-water fuel as an alternative to the traditional fuels, such as coal and oil.
