In steam boilers steam is being produced under pressure and super high temperature, by means of evaporating water. Due to the fact that only pure water evaporates, the concentrations of diluted salts in the remaining boiler water will increase, which can lead to corrosion and deposits.
Deposits of hardness salts (lime) will result in a loss of heat transfer capacity and potentially will lead to under deposit corrosion. These deposits can also result in leakage of boiler tubes due to super heating. Corrosion can also be a result of e.g. a (too) high Chloride level in the boiler water or a thickening factor which is too high.
Another common problem in steam boilers is corrosion by oxygen (resulting in pitting). To counter act on the above mentioned problems boiler water treatment is executed (softening and/or degassing among others) and the dosage of water treatment product for among others the control of rest-hardness, oxygen and carbon dioxide (carbon dioxide causes carbonic acid in the condensate piping).
Aquality scope of supply consists of a large range of boiler water treatment products. For every situation, depending on the type of system, sort of make-up water, materials and wall temperatures a selection can be made for the most suited and economical treatment.
