Exhaust air treatment RTO/3+
Type RTO/3+
Exhaust air treatment RTO/3+ – Regenerative thermal oxidation with integrated regenerative heat exchanger system. Flexible air volumes from 100 Nm3 up to 500,000 Nm3 and VOC concentrations up to 25% UEG.
– Regenerative thermal oxidation with integrated regenerative heat exchanger system. Flexible air volumes from 100 Nm3 up to 500,000 Nm3 and VOC concentrations up to 25% UEG.
The system always consists of at least 3 thermally-separated regenerator chambers. Switching the individual chambers from solvent laden to clean air operation is performed by double operation of poppet valves or butterfly dampers with air purge system.

After switching from solvent laden to clean air operation, the lower part of the regenerator chambers is flushed out with fresh air. This is to ensure that after switching no concentration peaks appear in the clean air.
The chambers are filled with ceramic accumulators. They are covered with a ceramic insulation layer. Above the regenerator chambers is a central combustion chamber that is also covered with a ceramic insulation layer. This also contains the support/booster burner system.
In addition, the internal pipework (solvent laden collector and clean air collector) and the required fans always belong to the system.
The regenerative, purely thermal exhaust air treatment system can be operated from small VOC concentrations of approx. 1.5 g/Nm3 autotherm. That means no further primary energy additive (oil, gas) is required for safe oxidation of VOC’s. Concurrently the system can be used as safe and flexible solution for oxidation of all organic exhaust airflows. Even the constantly tightening legal provisions for clean air values are reliably maintained.
Hydrocarbons are oxidised to carbon dioxide and water in a temperature range of approx. 800 – 840°C.
The oxidation energy released is used for pre-warming process exhaust gases. Concurrently the residual oxidation energy can be fed back into the process. This can be performed either direct via a hot gas outlet or indirect via an air-to-air heat exchanger.
The systems are completely process-controlled and require minimal servicing.
