Managing fouling in Polymer Air Preheaters
How the air preheater cleans itself and is kept free from fouling
Significant energy savings can be achieved when heat is recovered from hot flue and exhaust gases. When these hot flue and exhaust gases are fouling, management of this fouling is important in order to avoid heat exchanger blocking. The HeatMatrix polymer air preheaters have operated successfully in duties where the hot gas was dirty or the cold inlet air contained pollen or fines.
Summary
- Ultra High Performance Polymers with a very low affinity to bind with inorganic elements and dust particles
- Vertical positioning of the bundles minimizes the build-up of fouling
- Removal of heavy fouling with an optional in-line cleaning system
