FIELD: technological processes.
SUBSTANCE: invention discloses a method of producing coal-fired fuel, which includes steps of crushing coal, wet milling, mixing with water to produce a coal-water suspension, stabilization of crushed coal and dehydration, characterized by that wet grinding of coal is carried out to size of 100-150 mcm, and coal dehydration is carried out in centrifuge on moving renewable filtering surface with free cross-section of 40-50% at rotor rpm of 200-250 min-1 to moisture content of 5-7%, wherein the recovered liquid (fugate) after dehydration is returned to the mixing step.
EFFECT: technical result consists in improvement of calorific value of fuel in 1.40-1.55 times with reduction of moisture content.
