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

The HeatMatrix polymer air preheater is 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 air preheater 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.
