Waste heat recovery from Regenerative Thermal Oxidizers and Incinerators
Cold spot corrosion problems and mechanical failures limit heat recovery on Regenerative Thermal Oxydisers (RTO) and Incinerators. Polymer economisers and air preheaters are corrosion resistant and designed for leak proof thermal expansion.

Prevent corrosion & fouling
Your Regenerative Thermal Oxidizers (RTO) and Incinerator have waste heat recovery potential
Heat recovery on RTOs and Incinerators can be limited by corrosion and mechanical failures
How to recover more waste heat from your RTO or Incinerator
Waste heat recovery systems for RTO's and Incinerators
Polymer Air PreHeater
Heat up off-gas before treatment by extracting heat from flue gas. The air preheater is corrosion resistant & anti-fouling and is easy to maintain and clean.
Stainless steel or Polymer Economiser
Warm up boiler feed water, make-up water or process water with waste heat from flue gas. The economiser is corrosion resistant & anti-fouling and is easy to maintain and clean.

Within the Together Towards ZERO program, Carlsberg strives to make their breweries more sustainable. One of the steps taken in their Ukraine brewery is using a biogas fired steam boiler.
Due to the usage of biogas, high concentrations of sulphur elements can be found in the flue gas. If the flue gas is cooled down, these sulphur components condense and form sulphuric acid which is very corrosive. To prevent this from happening, Carlsberg operated their system such that the flue gas was at a high temperature (>140 °C) leaving the stack. Additional heat present in the flue gas was not used.
HeatMatrix installed a Polymer Air PreHeater which allowed Carlsberg to cool to temperatures below the acid dew point and achieve additional heat recovery on their steam boiler. There are no corrosion issues because of the corrosion resistance of the polymer used in the HeatMatrix APH. Based on the success in Ukraine, Carlsberg Serbia introduced the same solutiton on their biogas fired boiler.
