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 History of feedwater treatment· Characteristics of boiler feedwaterDetermination of the Hardness of Water Water Hardness chemistry.bd.psu.edu/jircitano/Water09.pdf· PDF Another effect of hard water is "boiler scale". When hard water comes into contact with dissolved carbonates, determine the hardness of an unknown water sample. Since both EDTA and Ca2+ are colorless, it is necessary to use a special indicator to detect
