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.

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.
