Swapan Basu, Ajay Kumar Debnath, in Power Plant Instrumentation and Control Handbook, 2015. 1.4 Boiler Feed Pumps. 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. It impels the FW with requisite pressure that dictates the working or operating point of steam generation.

Apr 01, 2012· Plant steam pressure was 215-225 psig and feedwater pressure was normally 320 to 340 psig with one pump in service. Each pump was rated for 290 gpm at 720 feet of head. The deaerator was being operated at 7 psig (233 °F); however, it was installed on the roof of the boiler building with a pump suction elevation head of 45 feet.

The boiler undergoes thermal shock when cold water is introduced to the hot surfaces of the boiler wall and its tubes. Hotter feedwater means a lower temperature difference and less risk of thermal shock. To maintain the designed output. The lower the boiler feedwater temperature, the more heat is required in the boiler to produce steam.

How to Feed a Low-Pressure Steam Boil

Oct 24, 2018· A low-pressure boiler is one that never goes above 15 psig. And since the folks who make boiler-feed pumps like to have a one-size-fits-all pump, they provide one on all their stock units that that will discharge at 20 psig because high pressure goes to low pressure. Always. And to get water into a boiler that’s operating at 15-psi, you need ...

Boiler feed pumps help feed water to steam generators such as boilers. Boilers are pressurized tanks used to heat and vaporize water into steam. In order to produce steam, boilers and steam generators require feedwater. General applications are building heat, power generation, and sanitation processes. Multistage pumps are often used for boiler feed because the process requires high pressure.

We prefer not to use these expensive control valves on low- and medium-pressure boilers with feed pumps at 100 hp and smaller. Generally orifice pipes are more reliable and economical. At a boiler load below 25% to 40%, the feedwater pump will be operating on the “flat part of the curve.” An ARC valve is simply not accurate enough to detect ...
