Boiler feed water is used to produce steam. The pressure of the steam (0,5 - 100 bar) determines the temperature and energy capacity, but also the quality of the feed water. The general rule is the higher the pressure the more strict the quality of the boiler feed water. Problems caused by impurities in the feed water are: Scaling. Corrosion.

A boiler is a closed vessel where water under pressure is transformed into steam by the application of heat. This process is useful for a variety of industries, from industrial and manufacturing environments to food and beverage processing. In the boiler furnace, the chemical energy in the fuel is converted into heat.

2015/2/20 · Importance of boiler water treatment. >Low pH or dissolved oxygen in the water attacks the steel. This causes pitting or lowering the thickness of the steel tubes, leading to rupture of the boiler tubes. >Water contains dissolved salts, which upon evaporation of water forms scales on the heat transfer surfaces.

In boiler water condensate the concentrations of organics are low, typically in the range of 0 – 15 mg/l and are measured between the condenser and the return condensate line. TOC analysis has been available for many years as an on-line measurement predominately using three different methods. - Molecular Absorption at UV 254 nm.

2015/5/5 · It is necessary to treat the boiler water to produce protective coat on the tubes required for good quality water & steam. For this it is necessary that the water shall be low controlled alkaline, very low level of dissolved Oxygen and very low presence of ions like Cl–. Silica from CW is another damaging factor as it deposits on turbine.
