Corrosive exhaust air is cooled below the water dew point resulting in a reduction of the energy consumption of the dryer of 8%.


HeatMatrix Polymer Air Preheater
Previously no heat was recovered from the exhaust air of the dryer, because of the high hydrochloric acid content in it. When cooled down, through the water and acid dew point, hydrochloric acid is formed and corrosion occurs. A HeatMatrix polymer air preheater was selected, because of its ability to handle corrosive exhaust air.
Energy savings of 170kW
Incoming cold air is heated from 10 to 56 °C, resulting in an energy saving of 170 kW. Corrosion free heat recovery is achieved.
