The function of the condenser is to condense the steam coming from the turbine exhaust. A high vacuum is maintained to extract steam and then cooled vis-a-vis condensed through an exchange of heat with the cooling water from a separate source.
The subsystems comprised are indicated below:
Steam Ejectors or External Vacuum Pumps, Vacuum Breaker;
Circulating Water Pump System or Cooling Towers;
Condensate Extraction Pumps;
Heat Exchangers (Drain/Gland Steam Cooler, LP Heaters).
