30 bar high pressure steam boiler feed water pump


Characteristics of boiler feedwater - Lenntech

Since water impurities cause boiler problems, careful consideration must be given to the quality of the water used for generating steam. The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler design.

Boiler feed pump | KSB

Boiler feed pumps operate at fluid temperatures of 160 to 210 ºC. In exceptional cases the temperature of the fluid handled may be higher still. Feed pumps for 1600 MW nuclear power stations are constructed for mass flow rates of up to 4000 tonnes/h and feed pump discharge pressures of 70 to 100 bar.

Feedwater - an overview | ScienceDirect Topics

6.1 Feed Water (FW) System. Feed water can be defined as return condensate + make up water. Feed water is the high-pressure deaerated (removal of gases such as oxygen and carbon dioxide) water supplied to the boiler from which steam is generated. In the case of SC or USC boilers, the feed water has additional significance.

6 Facts about Boiler Feed Water Pumps - Empowering Pumps and Equipment

2019/6/5 · Boiler feed water pumping applications typically require high pressures due to the high temperatures of the feed water. Water changes to a gas state at 212-degrees F in atmospheric pressure. However, boiler feed water ranges are from 225- to 250-degrees F, and some can even reach temperatures as high as 350-degrees F.
