Boiler feedwater is the water which is supplied to a boiler. 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.

Proper treatment of boiler feed water is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. This leads to poor heat transfer and reduces the efficiency of the boiler.

A boiler feed water treatment system is a system made up of several individual technologies that address your specific boiler feed water treatment needs. Treating boiler feed water is essential for both high- and low-pressure boilers.

Characteristics of boiler feed water Water absorbs more heat for a given temperature rise than any other common inorganic substance. It expands 1600 times as it evaporates to form steam at atmospheric pressure.

Make-up water to steam boilers should be treated with oxygen scavengers to avoid serious corrosion problems.

In this article, we will learn about the boiler feed water circulation system, natural, forced, combined circulation, and blowdown water. Boiler-feed water in power plants plays a crucial role in steam generation. This feed water circulates within the tube, boiler drum, and header.

Nov 27, 2024 · What Is a Boiler Feed Water System? A boiler feed water system sends treated water to your boilers. Boilers need treated water to work efficiently — any impurities or supply issues can reduce their efficiency. The feed system regulates water pressure and treats the water to avoid these problems.

Most items of plant in the boiler house are duplicated, but it is rare to have two feedtanks and this crucial item is often the last to be considered in the design process. The feedtank is the major meeting place for cold make-up water and condensate return.

The most appropriate boiler feed water treatment system will help the facility avoid costly plant downtime, expensive maintenance fees, and boiler failure as a result of scaling, corrosion, and fouling of the boiler and downstream equipment.

Boiler feed water is used to produce steam. The pressure of the steam (0,5 - 100 bar) determines the temperature and energy capacity, but also the quality of the feed water. The general rule is the higher the pressure the more strict the quality of the boiler feed water.
