The TO is capable of processing exhaust air streams with a high solvent load. The exhaust air preheater, which is used to preheat the exhaust air before it enters the combustion chamber, is an integral part of the TO. The combustion chamber is equipped with the Eisenmann BLUEMAX burner. Its use makes it possible to operate the combustion chamber in compliance with the strict CO specifications. At the same time, it is guaranteed that the TOC and NOx emissions are significantly below their regulatory limit values.
