METHOD OF MUTUAL GASIFICATION OF SOLID DUST-LIKE FUEL SUSPENDED IN FLUID MEDIUM AND ASH-PRODUCING LIQUID FUEL

The invention relates to a process for the combined gasification of a solid, pulverulent fuel suspended in a fluid medium and an ash-containing liquid fuel in a gasification reactor which is designed for the partial oxidation of solid pulverulent fuels with technical-grade oxygen and, if appropriate, steam under elevated pressure in the flame reaction. The aim of the invention is an economically advantageous and flexibly integrated gasification of combustible, but ash-containing liquid residues, while fully ensuring technical safety. The invention is based on the object of developing a process, which is simple in terms of safety engineering, control engineering and technology, for the gasification of combustible, but ash-containing residues, preferably ash-rich tar oil residues from coal refining. According to the invention, the ash-containing liquid fuel is fed separately and independently of the burner(s) together with steam via a feeding device to the reaction space in such a way that the steam causes atomisation of the ash-containing liquid fuel and serves at the same time as a flushing medium for the feeding device, and that the technical-grade oxygen required for the autothermic partial oxidation of the ash-containing liquid fuel... together with the oxygen intended for the gasification of the pulverulent fuel... by means of a common oxygen flow measurement and ...
