WATER-SLURRIED FUEL MANUFACTURE METHOD Russian patent published in 2004 - IPC

Abstract RU 2230098 C2

FIELD: alternative fuels. SUBSTANCE: invention relates to processing of rejected coal dust and non-commercial fines into improved-quality household- and technology-destined fuel. Processing involves preliminary treatment of coal slimes with water to give slurry containing 100 to 400 g/l solid phase. Resulting slurry is concentrated in apparatus wherein mineral rock with part of water is separated to produce fuel with 75 g/l water phase. Separated mineral rock and part of water are subjected to additional separation to clarify water, which is returned into slurry preparation stage. EFFECT: enabled utilization of highly dispersed coal slag and enlarged assortment of water-slurried fuels. 4 cl, 2 ex
