The pump room is located along the west wall of the power station on the basement floor. It sits under the turbine hall's boiler control section, which consists of relays and switches to control the steam injectors and boilers. One floor further up on the mezzanine floor is where the surge and boiler feed water tanks are located.

The Condensing Process

The Pump Room circulated water for the condensers, which are heat exchangers that convert steam into a liquid state by cooling it.

The process starts when water is heated to create steam, which expands in a turbine to drive it and generate electricity.

After the steam has passed through the turbines, it enters the condenser and comes into contact with cool water (or a cool surface). As the steam loses its heat, its temperature drops until it reaches dew point, changing from steam to liquid. The pure condensed water is then pumped back into the boiler to be reheated into steam, completing a cycle and conserving water.

Surface condensers are usually used in power plants, where tubes separate the steam and cooling water. While the steam is condensing on the outside of the tubes, cooling water is flowing through them.
