Thermal oxidation

The raw gas is pressed through the fan positioned on the raw gas side or sucked through the system by means of a fan positioned on the clean gas side.

The raw gas first flows through the raw gas/clean gas heat exchanger, in which the raw gas is preheated by the hot clean gas from the combustion chamber in counter-flow. The raw gas is then fed into the combustion chamber and leaves it again as clean gas.

There are applications in which the raw gas cannot be preheated. In these cases, the raw gas is fed directly into the combustion chamber and heated there only by the existing heat source, which means that more connected power is required.

In the combustion chamber itself, the raw gas is heated to the required combustion chamber temperature by a burner or electrical heating. The pollutants are oxidized by the dwell time and mixing in the combustion chamber.

The clean gas often contains so much residual energy that secondary heat recovery will pay for itself.
