RECOMMENDED STEAM PURITY

Technically pure steam is of such quality, that it does not cause deposits in the steam pre-heaters, in the fittings, heaters as well as in the turbine, which might require the intentional shut-down of the boiler or some part of the equipment, for their cleaning, outside of the normal equipment maintenance program. The recommended or limit values of the purity of steam are stated in the following table. The values are given in the maximal allowable day average concentrations. The concentration of the chlorine ions may be max. 3 µg.l-1.

1) Measured after the flow through strong acidic H-katex. NOTE: The measurement of the electrical conductivity γ at 250 C (µS/cm-1) must be done

without the presence of operational chemical agents, e.g. ammonia or hydrazine, which tends to increase the conductivity. This is why the measurement of specific electrical conductivity has to be done after the flow of the sample through the strong acidic H-katex, which is the filter that keeps all cations of the chemical compounds. By the filtration chemically pure water can be obtained.
