A process for preparation of aqueous -lignite suspension, consisting in grinding of brown coal, its degradation and treatment with water-repelling agent (paraffin, oil sludge) under suction with subsequent milling in the presence of 0.5-3.0 wt. % of rheological additive, at weight ratio water: solid phase 1:(1.3-1.4). The process implementation allows to obtain aqueous suspension with content of solid phase of 58.2 %, with stability of 10-16 days at period of fuel production 1.4-1.7 hours. The process can be used for production of liquid fuel from coal, appropriate for pipeline transportation and direct combustion in energy generating installations. |
