Abstract (en)
[origin: EP0718579A2] A heat exchanger to cool cracked gases has a pair of concentric tubes (6,4), forming a cooling jacket around the gas in the inner cooling tube (4). At each end of the tubes a chamber (7,8) is welded to them, for the supply and removal of cooling medium. In the novel construction, the water chambers are sturdily fabricated from thick metal strip, and have a number of tube assemblies along their length. For each cooling tube (4), there is a surrounding circular depression (11). These are spaced apart along the strip and their diameter is at least as large as that of the outer tube (6). At the base of each depression is a thin circular section (12).
