Boiler feed water - Lenntech

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.

Carbohydrazide is used as an oxygen scavenger for water boiler feed and heating systems to prevent corrosion damage. When used as de-oxidant in the boiler, put this product into water or use its water solution, the dosage of 0.5mol or above of carbohydrazide for 1mol O2 is preferred. The suitable temperature range is 87.8-176.7℃.

Acidic corrosion in boilers - Lenntech

Feed water can also become acidic from contamination of the system (process contamination of condensate or cooling water contamination from condensers). Acidic corrosion can also be caused by chemical cleaning operations (overheating of the cleaning solution, excessive exposure of metal to cleaning agent, high cleaning agent concentration).

Boiler Water Treatment - AWT

The water supplied to the boiler, which is converted to steam, is called feedwater. This feedwater system removes any impurities in the condensate, which is steam converted back to water, preheats and pressurizes it then returns it to the power boiler steam drum. The power boiler control system maintains the proper flow of feedwater to the boiler.
