METHOD OF PRODUCING REFINED COAL IN THE PROCESS OF ITS PREPARATION FOR COMBUSTION IN THERMAL POWER PLANT

摘要

The invention relates to power engineering and can be used in thermal power plants. In the method of producing refined coal in the process of its preparation for combustion in thermal power plants using staff and additional separators installed in the gap of training coal dust and its supply to the burners of the boiler. According to the invention, after the regular separator installed in the gap on the return line domelyuvannya coarse fraction enerhonapruzhenyy mill, which pulverized coal fraction to no more than 15 microns. Crushed coal sent to an additional separator in the form of gravitational-inertial separator. Light fraction on gravity-inertial separator is sent to the boiler burners or the dropping nozzles dense fraction containing pyrite and waste rock, is sent for recycling or landfill. The technical result of the invention is to reduce sulfur coal that goes to incineration, obtaining mechanically activated charcoal that can be used for firing boilers or illumination flare burners to reduce mechanical air-dried brick, ash content of coal and increase its calorie content.
