Heat recovery systems for flue gas in the Ceramics industry
Do you need to reduce your energy consumption? Our experts determine your heat recovery opportunities and implement the best heat recovery system in your ceramics plant.
Reduce energy consumption
Solve Fouling issues
Your oven or kiln is losing energy via the stack
What is keeping you from recovering this energy?
You lack time to investigate energy saving possibilities.
Corrosive and fouling flue gases
Flue gas from your kiln or oven is corrosive and fouled.
We design and deliver heat recovery systems for Ceramics plants to reduce their carbon footprint
Save energy on your thermal process
Recover heat - that is now lost - from flue gas.
Your oven or kiln has waste heat recovery potential
Recover more heat from Ovens and Kilns
Recover more heat from the flue gas of your oven to preheat air for the drying chambers or to recycle more heat to the first section of your oven.
The way our heat recovery system works
Capture waste heat
Exhaust air from the oven and flue gases are released to the atmosphere through the chimney. Our heat recovery system captures this heat from kilns or ovens.
Preheat air or water
Cold combustion air, drying air or process water is heated with the captured waste heat. This directly reduces the consumption of fossil fuels.

Polymer Air Preheater
Stainless steel or Polymer Economiser
Warm up process water with waste heat from flue gases. The economiser is made corrosion resistant and is easy to maintain and to clean.

Polymer Air PreHeating technology researched under the harsh conditions of a brick plant
In the ceramics industry flue gases are released from the oven at a temperature of 100-200 °C. This flue gas is sent directly to atmosphere and a significant amount of energy is lost. Main reason for not recovering heat from this flue gas is the presence of sulphur oxides, chlorides and fluorides and fouling. When cooled down, an acidic condensate is formed which causes corrosion and fouling accumulates.
Polymer heat recovery systems of HeatMatrix are specifically designed for heat recovery from corrosive and fouled flue gases. A test setup was installed at two brick manufacturers with corrosive and fouling flue gases.
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.

How do I save energy on my production site?
For the production of ceramics, ovens are used. An oven or kiln loses a lot of hot flue gas through the stack. By recovering the heat from this flue gas to preheat combustion, circulation or drying air, a significant reduction in energy and CO2 emission can be achieved. Alternatively, the waste heat can be used to warm up water for further use.
Heat recovery has been tested before in the ceramics industry, but without success. Why does your system work?
The two challenges facing heat recovery in the ceramics industry are corrosion and fouling. For these challenging duties, we offer an innovative solution, based on polymer heat exchange technology. The solution is corrosion resistant, slows down the build-up of fouling and is easy to clean with a built-in cleaning system.
How do heat recovery systems of HeatMatrix solve corrosion problems?
Elements from the clay and fuel form acids in the flue gas, like HF and H2SO4. These acids will condense out when the flue gas temperature drops below - what is called - the Acid Dew Point. This condensation leads to corrosion of surface materials. Our polymer heat exchange technology allows flue gas to be cooled without having the risk of corrosion.
What causes my fouling?
The flue gas contains a number of foulants: dust from the bricks and tiles, condensed acids, salt from the clay and soot coming from the combustion. The foulants are sticky and will block downstream equipment. The polymer heat exchangers have a low tendency of chemical bonding and a very smooth surface. Therefore there is a lower degree of fouling. An in-situ cleaning system is installed which cleans during operation.
