Reuse, recycle and recover waste heat energy from your brick kilns to power your business

Brick kiln exhaust temperatures will reach 200oC during the initial stage of the drying process before firing up to around 1000oC, with a variety of toxic components in the exhaust gases. These include halogens, particularly chlorides and fluorides, and the potential for material attack in both the gas and liquid phase.

Operational’s air to air heat exchangers are constructed from special stainless steels to resist corrosion attack; however, due to the impurities present, control of the heat exchanger internal skin temperatures is important to ensure condensation is minimised. Recovered hot air is re-used as pre-heated make-up air and combustion air for the kiln operation. A return on investment was provided in around 2 years.
