Power Plant Boiler Feed Water Pump

The double casing is also called barrel type.

Power plant boiler feed water pump.

Boiler feed pump for power plant operation. A feedwater pump is most often driven by an electric motor for energy efficiency. Boiler feed pump take the suction from the deaerator and send the water to the boiler in starting of the boiler light up we take the boiler feed pump. Today we discuss about the boiler feed pump it s a very critical component each and every power plant industry.

This is the multi stage pump having the double casing the inner casing contained in the outer casing. 1 4 boiler feed pumps. A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler the water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler. Pre heating feed water heaters using extracted steam from the turbine adds a part of the sensible heat even before the water enters the boiler.

Boiler feed water pumps are commonly centrifugal pumps. Boiler feed water pump pumps the water at high pressure into the boiler from the feed water tank.

Among various boiler feed water pumps this pump is adopted for high pressure and high temperature application as in the subcritial steam power generation. We can say it is a heart of boiler. The pump is akin to the heart in the human body. These pumps are normally high pressure units that take suction from a condensate return system and can be of the centrifugal pump type or positive displacement type.
