Beschreibung
Zusammenfassung:	The invention 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. In the coal gasification method, a gasifier is fed with a uniform activated coal water fuel, the droplets of which are of equal size and the coal particles in said droplets having a 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 the coal for the activated coal water fuel preparation method 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 invention provides for more extensive recovery of thermal energy from coal and more efficient electricity generation.
