Boiler Water Quality Requirements and Associated Steam
Boiler Water Quality Requirements and Associated Steam Quality The purpose of this manual is to acquaint engineers, purchasers, and operators of industrial, commercial and institutional (ICI) boilers with ABMA’s judgment as to the relationship between boiler water quality and boiler performance.
Boiler Efficiency and Steam Quality: The Challenge of
When a large amount of feedwater enters the boiler, the steam space above the water level becomes foggy. This fog and the resultant water-contaminated, low-quality steam continue until the water in the boiler becomes reasonably isothermal. The second problem is the suppression of the rate of steam production.

the boiler water should be maintained at pH 11. This may require an addition of alkali if the water is not soft. Secondly, a chemical called a sludge conditioner can be added to treat the solids so that they drop out (precipitate). Finally, these treated solids must be removed from the boiler by blowoff.

As a result, proper boiler water quality can be maintained at all times. Also, a maximum of dissolved solids may be removed with minimal loss of water and heat from the boiler. Another major benefit of continuous blowdown is the recovery of a large amount of its heat content through the use of blowdown flash tanks and heat exchangers.
