Power Plant Boiler Feed Water Pump

Boiler feed pump for power plant operation.

Power plant boiler feed water pump. 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. Today we discuss about the boiler feed pump it s a very critical component each and every power plant industry. 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.

This is the multi stage pump having the double casing the inner casing contained in the outer casing. A feedwater pump is most often driven by an electric motor for energy efficiency. To ensure a high enough head and pressure boiler feed pumps have been arranged in series multistage pumps. 1 4 boiler feed pumps.

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. We can say it is a heart of boiler. The double casing is also called barrel type.

It impels the fw with requisite pressure that dictates the working or operating point of steam generation. 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. 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.
