Beschreibung
Zusammenfassung:	This specification relates to the field of power engineering and, more specifically, to systems for generating electricity based on the use of solid fuel, primarily brown and black coal. A coal gasification method is disclosed in which a gasifier is fed with a uniform activated coal water fuel. The droplets of fuel are ideally of equal size and have coal particles with similar granulometric composition. The fuel droplets are introduced intermittently in separate doses of fuel with a certain amount of motion being imparted thereto. The milling of coal for activated coal water fuel preparation is adjusted adaptively according to the criterion of the actual amount of volatile substances given off by the coal, and the coal is thoroughly classified according to its granulometric composition. The disclosed method can enable more extensive recovery of thermal energy from coal and more efficient electricity generation.
