Research shows potential of heat recovery with a polymer Air PreHeater within the Ceramics industry.

Heat recovery from oven flue gas

No corrosion issues

Easy cleaning of heat exchanger

Heat recovery in the ceramics industry

In the ceramics industry flue gases are released from the oven proces at a temperature of 100-200 °C. This flue gas is sent directly to the atmosphere and a significant amount of energy is lost. Main reason for not recovering heat from this flue gas is the presence of sulphuroxides, chlorides and fluorides. When cooled down, an acidic condensate is formed which causes corrosion. 

Test with HeatMatrix polymer APH

HeatMatrix polymer heat recovery systems are designed for heat recovery from corrosive flue gases. A test setup was installed at two brick plants, both having corrosive and fouling flue gases. 

Successful heat recovery results

The pilot tests showed that the HeatMatrix polymer APH is able to handle both corrosion and fouling aspects of the flue gas. The installed cleaning system in combination with the smooth surface of the polymer make it possible to clean the heat exchanger within 3 minutes and remove accumulated dust and particles.
