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.

Boiler efficiency increased 4%HeatMatrix polymer APH technology gave us the opportunity to recover additional heat from our steam boiler and make our process more sustainable. After installation of the polymer APH, our boiler efficiency increased with 4% and no corrosion issues occured since then.
For more than 10 years we design and deliver heat recovery systems for industrial factories
