Optimal protection of a district heating system is not very different from the way other types of installations are protected. However the focus lies mainly in the measurable and isolated components taking into consideration the risks of having bacteria and sludge in the system.
Kemi-tec’s concept in terms of district heating:
A hardness stabilisation product that among others contains:
Caustic soda (NaOH) to adjustment of the pH value.
Also a one-shot concept is developed (pH, oxygen scavenger, sludge/scale dispersants).
This gives the opportunity to regulate every single protection component independently of each other by common self-checking. The Danish District Heating Association recommends this method.
You would often use volatile oxygen absorbents (DEHA) for protecting the edge zone. This also applies in case of a lack of nitrogen surplus in the upper part of the tank.
