COAL GAS TREATMENT APPARATUS

摘要

In a device for the treatment of synthesis gas produced by coal gasification, a vertically extending shell is connected to a coal gasification reactor so that the interior of the shell is in direct communication with the interior of the reactor. The interior surface of the shell is lined with upwardly extending heat exchange tubes. Additional heat exchange tubes in combination with the tubes lining the shell form a plurality of upwardly extending chambers projecting radially inwardly from and spaced angularly apart about the tube lining. Tubes coextensive with the heat exchanger tubes forming the lining, are located within the chamber for conveying a cleaning fluid. The tubes are arranged to direct the cleaning fluid approximately tangentially of the heat exchanger tubes lining the shell for cleaning the exterior surfaces of such tubes.
