ABSTRACT:
A heat exchanger for two vapor media comprises a number of straight tube bundles arranged in side-by-side horizontal relation and so connected with each other that heating steam flows through them in series. Each tube bundle is provided with a distributing chamber at the steam entrance end and a receiving chamber at the steam discharge end, a condensate drain is provided at each receiving chamber, the heating steam is throttled as it passes from the receiving chamber of one tube bundle to the distributing chamber of the next tube bundle in the series, the heat exchange areas of the tube bundles diminish in the flow direction such that the heating steam first flows through the tube bundle having the greatest heat exchange area, and steam to be superheated flows in heat exchange relation with the exterior surfaces of the tubes in a cross-counterflow manner.
