Power Plant Boiler Feed Water Pump

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.

Power plant boiler feed water pump.

It impels the fw with requisite pressure that dictates the working or operating point of steam generation. The pump is akin to the heart in the human body. Today we discuss about the boiler feed pump it s a very critical component each and every power plant industry. We can say it is a heart of boiler.

Boiler feed water pumps are commonly centrifugal pumps. 1 4 boiler feed pumps. Often two steam turbine driven turbo pump and two electric feedwater pumps are used. Among various boiler feed water pumps this pump is adopted for high pressure and high temperature application as in the subcritial steam power generation.

The outlet of a deaerator is connected to the boiler feed pump bfp suction and from there to the popular term of the working fluid feedwater to reach the boiler proper. This is the multi stage pump having the double casing the inner casing contained in the outer casing. Boiler feed water pump pumps the water at high pressure into the boiler from the feed water tank. To ensure a high enough head and pressure boiler feed pumps have been arranged in series multistage pumps.

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. 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. The double casing is also called barrel type. Swapan basu ajay kumar debnath in power plant instrumentation and control handbook 2015.
