Boiler feedwater - Wikipedia

Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank.

Reasons why steam boilers flood, and where to look for

It should be between seven and nine. A pH of 11 or higher will make the boiler water foam. Foaming water will leave the boiler with the steam, and that will lower the boiler's water line. The automatic water feeder will respond by adding water to the boiler. When the condensate returns from the system, the boiler will flood.
