The bottom part of the condenser that collects the condensate formed after the steam performed its work.

A condensate pump removes the condensate from the hotwell and discharges it to the boiler feed pump.

Sometimes booster pumps are installed between the condensate and boiler feed pumps to prevent the hot condensate from flashing and causing cavitation problems.

A surge tank, de-aerator or some other type of collecting vessel is located between the condensate pump and the boiler feed pump to compensate for the differences in capacity of these two pumps.

  • C= Condenser
  • H.W. = Hotwell
