Chemical Feeding and Feed Systems for Water/Steam Circuits - eBook

The aim of the VGB-Standard VGB-S-042-0-2018-01-EN is to specify and explain methods and systems for the chemical treatment of make-up water, boiler feed water, steam and condensate for the operation of water/steam cycles.

This VGB-Standard contains instructions and recommendations for both the planning and operating stages. The methods described, equipment as well as chemical feed systems may also apply correspondingly to the internal chemical treatment/feeding of other systems (e.g. intermediate cooling system, district heating, and the like).

The VGB-Standard VGB-S-042 does not apply to nuclear power plants, district heating nets and geothermal plants.

For cooling water circuits and auxiliary plants (e.g. water treatment, flue-gas cleaning systems) the respective guidelines/standards shall be taken into account.
