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.

Water Tube Boilers | Spirax Sarco

However, when the pressure in the water-tube boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs. To keep the same level of steam output at higher design pressures, the distance between the lower drum and the steam drum must be increased, or some means of forced circulation must be introduced.

Steam and Condensate - A basic overview of a steam system - The Boiler House

The hot gases from the burner pass backwards and forwards up to 3 times through a series of tubes to gain the maximum transfer of heat through the tube surfaces to the surrounding boiler water. Once the water reaches saturation temperature (the temperature at which it will boil at that pressure) bubbles of steam are produced, which rise to the water surface and burst.
