A method for production of energetic fuel from heterogeneous coal relates to thermal power. The initial coal is grinded to separation size from 1 to , simultaneously dried and grinded in the flow of heat carrier of jet mill. The grinding is stimulated by excitation of oscillations in the field of own resonating frequencies of coal particles with formation of pulverized-coal and gas energetic fuel and particles of additives bigger in the size. The separation of formed fraction is carried out in cyclone. Time from charging of grinded coal particles into jet mill to output of pulverized-coal and gas energetic fuel from cyclone is set up less than 1.5 seconds. The invention provides reduction of power consumption, increasing of coal grinding level, and fuel quality increasing. |
