COOLING POCKET FOR A ROTARY DRUM COOLER HAVING A FLEXIBLE VENT PIPE ASSEMBLY

摘要

A rotary drum cooler for cooling particulate material (e.g. coke particles) having at least one cooling pocket which, in turn, includes a flexible vent pipe assembly which can slide in relation to the shell of the cooler. By making the vent pipe slidable, it can move in response to the expansion and contraction of the pocket within the shell. The vent pipe assembly is comprised of: a) a tube which is connected to the pocket and which slidably extends through an aperture in the shell; and b) a flexible means for sealingly connecting the outer end of the tube to the shell.
