Corrosion in POWER STATION CONDENSERS Available to Purchase

At the end of the second world war the electricity generating capacity of this country lagged seriously behind the consumer demand. In order to rectify this deficit two standard sizes of generating set were adopted. These were the 30 and 60 megawatts (MW) generators. Since then, to improve the Rankine cycle efficiency, set sizes have steadily increased and today 200‐MW sets are accepted practice and 550‐MW machines are being designed. The increase in turbo‐alternator size has had repercussions on condenser design, some aspects of which may increase the corrosion hazard. This has stimulated interest in the development of effective countermeasures, especially the application of cathodic protection.
