Abstract
An intermediate steam superheater includes a heat exchanger comprising a bundle of tubes supplied with steam and subject to the disadvantage that the steam may condense completely in some of the tubes while passing freely through others of the tubes with a consequent loss of heating efficiency. This is corrected by sucking the steam from the outlet ends of the tubes and injecting it into the inlet ends of the tubes so that such a high flow rate occurs through the tubes that the tubes are kept substantially free from condensate while the steam is continuously recirculated through all of the tubes, the condensate from the condensed portion of the steam being discharged from the heat exchanger.
