M Alkalinity For Feed Water Boiler

M Alkalinity For Feed Water Boiler

Characteristics of boiler feedwater - Lenntech

Since water impurities cause boiler problems, careful consideration must be given to the quality of the water used for generating steam. The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler design.

alkalinity – Water Technology Report

Alkalinity in the boiler, as well as minimising corrosion, also acts as a scale salts precipitant. As an example caustic alkalinity in the boiler will precipitate magnesium salts to form a mobile sludge that can be easily removed by blowdown, e.g. MgCl 2 + 2NaOH >> Mg (OH) 2 + 2NaCl
