Gasifier with a reduced number of coolant lead-throughs through the pressure jacket for the assemblies crude gas - and slag outlet as well as guide tube

摘要

In the case of a gasifier for the gasification of powdered or liquid fuels with a gasifying medium containing free oxygen at pressures between the ambient pressure and 8 mpa, as well as gasification temperatures between 1.200 and 1.900°C. are in a pressure jacket (1) a by means of a cooling shield (3) of limited reaction space above the assemblies crude gas - / slag opening on the one hand and fastened thereto guide tube, on the other hand, with a quenching chamber is arranged therebelow connected. The invention solves the at the junction of the two subassemblies overheating problem occurring in that an integral constructional unit is created which, in advantageous manner only a cooling-water supply system and / or only a cooling water discharge has through the pressure jacket.
