The object of research is processes of movement and combustion polydisperse coal fuel in the reactor of thermo-chemical preparation of solid fuel in thermal power plants. The subject of research is scientific rationale and numerical investigation of the influence of operating parameters on the thermo-chemical preparation of fuel. The purpose of work is development of algorithms, software and conducting of numerical analysis of the thermochemical processes and heat transfer in the turbulent flow in the advanced pulverized-coal burner reactor. The method of research is numerical. The fields of application of the work is mathematical modeling of the pulverized coal combustion in burners of thermal power plants and TPP burners design. V.2. Develop and analyze options schemes on the basis of gas-piston cogeneration based on maximum consumption produced with thermal and electric energy. Carried out a comparative analysis and selection of rational parameters considered cogeneration schemes under different operating gas powered thermal contour plant. At work steam-turbine power complexes at variable loads (winter and summer) analyzed the thermal circuit with a pair of compression or pressure turbines connected in high and low pressure. V.3. The object of the research are the processes of classification and dehydration of thin fractions sludge waste coal on screening surfaces with a vibration poly-frequency excitation. The dubject of research is the parameters of the vibrating poly-frequency screen for effective particle-size distribution and dewatering of sludge waste of coal washing. The purpose of work is the sidentification of parameters of the vibrating poly-frequency screen for effective particle-size distribution and dewatering of sludge waste of coal washing for inclusion theirs in energy transformation processes of low-reaction coal-dust fuel in implementing of energy saving technologies. v.4. The object of research is the processes of processing of carbon-containing medium of plasma gasification with high energy density and temperature fields. The subject of research is carbon-containing water-coal, aerodynamic and aerogas mixture, plasma-jet and plasma-arc reactors, their energy-intensive elements operational life. The purpose of work is the establishment of rational parameters of processes of plasma processing of carbon-containing medium and development of scientifically based recommendations to reduce the energy intensity of the process, increasing the degree of processing carbon and resource characteristics of technical means. The method of research is mathematical and physical modeling of processes, checking the results using experimental samples, debugging and technical-economic analysis of the final results.
