The pressure on the secondary side of the steam generator is too high
Steam Headers and Off Takes | Spirax Sarco
Referring to Figure 3.8.1, with all boilers operating at the same pressure, the pressure at point A has to be less than that at point B for steam to flow from point B to the plant. Consequently, there must be a greater pressure drop between boiler number 4 and point A than boiler number 3 and point B, whilst the difference in these two pressure drops takes place between A and B.

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.

Steam Piping Best Practices Introduction Just because it's 'been that way' for a long time, don't assume it's right. In many cases steam systems were designed long before there was any concern about energy efficiency. Systems may have not been installed
