ABSTRACT:
There is disclosed a heat exchanger having one or more bundles of tubes through which steam or other vapor is passed and comprising horizontally arranged rows of tubes each of which is connected to a separate outlet header. Condensate from the outlet headers of each bundle is drained into a pot having individual water leg seals which isolate vapor pressure within such outlet headers from one another. The outlet headers are of generally rectangular cross section and staggered in a horizontal direction, with the lower end of each successive outlet header to be contacted by air extending below the upper end of the preceding outlet header. The tubes of each such successive row of tubes are longer than those of the preceding row to be contacted by air and extend over the upper end of the outlet header connecting with the tubes of the preceding row of tubes.
