Flue gas aftertreatment NOx-filter

The large change in cross-section from the inflow to the DeNOx catalytic converter, in combination with the limited space available, and therefore two 90° deflections in front of the system, was challenging, as the DeNOx system was subsequently integrated into the existing waste incineration plant.

By adapting the deflection plates, especially on the second deflection, it was possible to achieve a uniform flow and therefore optimum performance of the DeNox system.
