Characteristics of boiler feedwater - Lenntech

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. If the feed water does not meet these requirements it must be pretreated to remove impurities.

Water Handbook - Boiler Blowdown Control | SUEZ

2019-6-21 · When sodium zeolite softened makeup is used, the need for boiler blowdown is usually determined by measurement of the boiler water conductivity, which provides an indirect measure of the boiler water dissolved solids. Other boiler water constituents such as chlorides, sodium, and silica are also used as a means of controlling blowdown.

Boiler Water Tests | Viking Water Technology, Inc.

Conductivity Test (Boiler and Condensate) Conductivity is a measure of the ability of water to conduct electric current. The ability to conduct electricity is related to the amount of dissolved (ionizable) solids in the water. Conductivity is generally read in units called micromhos, using a sample which has been neutralized with gallic acid to
