Sep 03, 2020 · Magnesium Chloride (MgCl 2) Magnesium Chloride, like Magnesium Sulphate, is soluble in fresh water. In the high temperature and alkaline conditions normally maintained in a boiler, any soluble Magnesium ions in the boiler water become extremely reactive with Hydroxyl ions, which may be present in high concentrations in this type of environment.

The ratio of chlorides in the boiler water to that of the feed water can be used as a means to determine the amount of blowdown required. The chloride test is unsuitable for feedwater with low incoming concentrations and the concentrations in the feedwater must be averaged over time for accuracy.

Water Treatment Storage and Blowdown for Steam Boilers

Boilers, however, are less able to cope, and these same minerals will cause damage in a steam boiler if allowed to remain. Of the world's water stock, 97% is found in the oceans, and a significant part of that is trapped in the polar glaciers - only 0.65% is available for domestic and industrial use.

Water for the Boiler | Spirax Sarco

Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence.

May 02, 2000 · boiler water chloride level should be monitored to ensure the blow down rate is correct. If the chloride level is higher than the recommended maximum, more blow down is needed. If it is low, excess blow down is occurring, resulting in wasted chemicals, water, and heat energy. In some cases the chloride level never approaches the recommended

Chloride, Salinity, and Dissolved Solids - USGS

The dissolved solids concentration in water is the sum of all the substances, organic and inorganic, dissolved in water. This also is referred to as "total dissolved solids", or TDS. Calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride, nitrate, and silica typically make up most of the dissolved solids in water.
