Abstract

A cooler for particle-laden gases in a coal-gasification plant, with an upright nest of hot-gas tubes that coil around the cooler's longitudinal axis inside its jacket and with a pipe for supplying a coolant inside the nest of tubes. The cooler has a ceramic-lined or liquid-cooled distributing head (1) with a central gas intake (2) at the top and with several diffusor-like gas outlets (3) at the bottom that open into the nest (4) of tubes and several gas outlets (5) below the nest. The hot-gas tubes are suspended from the coolant-supply pipe (v) on claws (7). The pipe has at least one intake (8) for the descending coolant and rests on a support (9) on the base (11) of the cooler or on supports (10) against the inner surface of the cooler. The mixture of steam and water ascending among the tubes is extracted through at least one outlet (14) on the jacket (12) of the cooler.
