Abstract
A process and system for cooling a dust-laden raw or untreated gas from the gasification of a solid carbon-containing fuel in a pressurized reactor. The gas from the reactor is introduced into a quench pipe that has a cross-sectional area that is smaller than the cross-sectional area of the reactor, and to which is supplied a quenching medium for direct cooling. The gas emerging from the outlet end of the quench pipe is deflected essentially by 180.degree. and, counter to the flow of the gas in the quench pipe, is guided through a cooling section that surrounds the quench pipe and is incorporated in a water-steam circuit.
