Prospects of electric pulse technology for production coal-water fuel (CWF) and extracted from coal deposits of rare elements

Abstract

Growing fuel consumption of ferrous, nonferrous and rare metals, non-metallic ore materials that are the basis for the development of the economy and modern industry requires an increase in production and processing of minerals. In recent years, be activated a new trend in the coal energy. There are technological solutions for the gasification of coal, produced water-coal fuel (WCF) and special equipment for its combustion. All these new technologies require a higher quality of coal fuel and sufficiently pulverizing coal - is not greater than 50 microns. Requirements to increase the number of processed ores in improving quality indicators processing (increasing the degree of extraction) put very important problem to streamline processes and reduce the cost of crushing and grinding. A fundamental solution to the problems of complex use of raw coal crushing and grinding it with minimal content ash, narrow particle size distribution, as well as enhance the complete extraction of the minerals it can be achieved on the basis of the process electric pulse destruction materials (EPD).
