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 intentionalshut-down of the boiler or some part of the equipment, for their cleaning, outside of the normalequipment maintenance program.

The recommended or limit values of the purity of steam are stated in the following table. Thevalues are given in the maximal allowable day average concentrations. The concentration of thechlorine ions may be max. 3 µ g.l-1.

NOTE: The measurement of the electrical conductivity at 25 0 C ( S/cm -1) must be donewithout the presence of operational chemical agents, e.g. ammonia or hydrazine,which tends to increase the conductivity. This is why the measurement ofspecific electrical conductivity has to be done after the flow of the samplethrough the strong acidic H-katex, which is the filter that keeps all cations of thechemical compounds. By the filtration chemically pure water can be obtained.
