Water treatment is an important part of steam generation. In oil- and gas-fired steam boilers, dosed solutions (dosage chemistry) are added to the feed water to protect the boiler from corrosion and dents.
JUMAG Dosage Chemistry: Function and Benefit
What are dosed solutions (dosage chemistry) used for and what are their advantages?
Prevent deposits and corrosion in the steam boiler
Dosed solutions bind free oxygen and carbonic acid, insofar as they are not released by thermal degassing (or even pressure degassing.)
The pH-value of the feed water is slightly raised to protect the boiler from corrosion.
Furthermore, the dosed solutions contain a corrosion protection and reduce dents. In almost every case, dosage chemicals are added to the feed water.
