HRSHeat Recovery System

The Wallstein HRS system is made from fluoropolymer allows to recover heat below the acid dew point of the flue gas.

 

HRS has 3 variants:

 

  1. Preheating the air

3.And switching between the heat supply network and condensate line of the plant.

HRS Advantages:

1. Excellent anti-corrosion properties. The raw material is fluoropolymer that will not corrode under any flue gas ambient temperature and can operate stably below the acid dew point.
2. Large heat exchange temperature difference. Maximum heat recovery can be achieved, and flue gas heat of 170°C-70°C can be recovered.
3. Good self-cleaning properties. Fluoroplastic materials have a low coefficient of friction, a non-sticky surface, are less likely to accumulate dust, resist scaling, and are easy to clean.
4. With self-lubricating properties, good wear resistance.
5. Excellent flexibility, bending fatigue and stress cracks.
6. The service life of more than 15 years is much higher than the service life of metal economizers.
