METHOD OF PRODUCING SMOKE-FREE LUMPED CARBONACEOUS FUEL Russian patent published in 2009 - IPC C10B57/04 

FIELD: oil-and-gas production.

SUBSTANCE: method of producing smoke-free lumped carbonaceous fuel relates to processing fine grained coal industry wastes and coal dust into refined fuel for technical, household and communal purposes through laminar coking. The method of producing smoke-free lumped carbonaceous fuel involves mixing coal sludge and coal dust and thermal processing, and is distinguished by that, the coal sludge is in form of waste coal, taken in amount of 15-35 wt % and the coal dust is ground gas coal of a fraction of less than 3 mm, taken in amount of 65-85 wt %, which are then treated with an inert heat carrier to temperature of 150-250°C after mixing and then coked.

EFFECT: faster laminar coking, design of non-waste technology for coal-preparation plants, increased mechanical strength of the fuel, possibility of using the fuel in industrial high-capacity furnaces with flame combustion mode, fluidised bed furnaces and grate-fired furnaces, reduced cost of the obtained fuel.
