METHOD OF COAL-AEROSOL POWER-PLANT FUEL PRODUCTION Russian patent published in 2003 - IPC

FIELD: heat-power engineering, technology of coal-aerosol power-plant fuel production. SUBSTANCE: invention relates to technology of production of the efficient and ecologically pure solid fuel on the basis of coal, that may be utilized for incineration in boilers, furnaces and other installations of heat-power engineering. Coal- aerosol fuel made on the basis of micronized activated coal and hydrocarbon compounds is produced by preliminary comminution of large-sized lumpy coal up to 2-3 mm in the devices provided with magnetic traps for trapping non- grinded metal impurities with following thin grinding exercised by a jet-rotor grinder up to particle sizes of 17-20 micromicrons and at the high-speed mode of operation lead up the coal moisture to 1-3 % with production of a stable aerosol system of heightened calorific value and the given moisture. EFFECT: production of the efficient and ecologically pure coal-aerosol power-plant fuel. 4 cl
