Abstract

A device for scavenging condensate from long heat exchange tubes by recirculating the steam which is passed through one portion of a U-shaped tube bundle through another portion of the tube bundle and thus reducing the build-up of slugs of liquid in the tubes by increasing the velocity therethrough without reducing the heat transfer surface and also protecting the welds which seal the tubes to the tube sheet from thermal shocks and stresses by incorporating a thermal sleeve in the device which cooperates with the scavenging of condensate from the tube to provide optimum protection.
