Abstract
A minor portion of low pressure exhaust vapor such as exhaust steam is compressed to a temperature above that which a major part of said exhaust vapor is being condensed, suitably by a centrifugal compressor driven by higher pressure vapor from the same source as that which powers a principal turbine that furnishes most of said exhaust vapor. The major part of said exhaust vapor is condensed and the resulting main condensate is passed into heat exchange with the compressed minor portion of the exhaust vapor for generating a heated resulting main condensate and a secondary condensate from condensation of the compressed exhaust vapor. These condensates are withdrawn, suitably for deaeration when the vapor used is steam.
Claims4
A process for heating a primary liquid condensate which results from condensing a supply of exhaust vapor from a primary turbine which comprises:
- compressing a minor portion of said exhaust vapor, the compressing of said minor portion being powered by a secondary turbine, the source for the secondary turbine being the same as that for the primary turbine;
- exchanging heat between said primary liquid condensate and the resulting compressed minor portion of exhaust vapor prior to any other heating of said primary liquid condensate;
- withdrawing from said heat exchanging the heated primary liquid condensate and a secondary liquid condensate resulting from condensation of said compressed vapor.
