Boiler Water Treatment Guidelines; Columbia Boiler Co

In boilers the hardness of the water can cause the formation of scale and sludge or mud. The hardness must be removed in the makeup water to the return system. Total hardness should not exceed 50 PPM. Oils. Every effort should be made to prevent oils from getting into the boiler water. Oil causes foaming, or combines with suspended solids to

How is Scale Detrimental to Boilers? - Complete Water

Oct 13, 2017 · What causes hardness in water to form scale on steam boiler surfaces? Calcium and magnesium hardness crystallizes and becomes scale in two ways. One way is through Inverse Solubility, which is the tendency of certain impurities in the water to crystallize and precipitate as the temperature of boiler water increases.

Reasons why the boiler water is dirty, and where to look

Jun 24, 2014 · That forces water up into the returns where it meets steam and creates water hammer. The water hammer can dislodge even more corrosion, which eventually washes down to the boiler and discolors the water. When these things begin to happen, dirty water is usually the least of your problems. Find the source of the excess feed water and get rid of it.

Boiler Water Quality Control - Complete Water Solutions

When water is evaporated and forms steam, the minerals or solids that were dissolved or suspended in the water remain behind in the boiler. To replace the water which is evaporated, we add make-up water with its normal load of minerals or solids. After a period of time the Total Dissolved Solids (TDS) within the boiler will reach a critical level.
