Poljakov of National Academy of Sciences of Ukraine popup.description2 As a result of researches on the topic the mathematical model for carrying out of numerical calculation of gas-dynamic and heat-exchange processes at influence of high-temperature plasma coolant on natural and technogenic materials is constructed, characterized in that by setting appropriate boundary conditions it takes into account the mutual influence of processes in the flow, which moves with the flow in the surrounding material. Assessment of technologies and technical means of processing carbon-containing media into gas by direct combustion and in the electric field of electric arc discharge is carried out. The advantage of the steam-plasma method of gasification in terms of technical and economic parameters is revealed. Methods for increasing the caloric content of the gas phase (magnesium) during the transformation of heterogeneous carbon-containing medium under the conditions of "flooded" arc discharge have been established. An assessment of the current state of vibration technologies of mineral processing has been made. The efficiency of vibration of essentially nonlinear systems for processing of natural and man-made materials is given. The most promising directions of improvement of methods and processes of vibration processing of mineral raw materials have been selected and substantiated. Various types of systems of accumulation of electric energy and the area of their application in power and in the conditions of coal enterprises are considered. The researches of principles of work of accumulators of different types are carried out. Options for constructing electrical energy storage for various applications based on lead-acid battery are offered. For the conditions of mining enterprises, a number of technological schemes for obtaining energy from renewable sources are justified, namely the use of wind power plants in conjunction with the network energy storage, as well as the accumulation of mine water by lifting from the lower horizons to the upper one Product Description popup.authors Bulat Anatoliy F Voloshyn Oleksij I Semenenko Evgen V Shevchenko Heorhiy O popup.nrat_date 2020-04-02 Close
