Flue gas aftertreatment NOx-filter

DeNOx systems, also known as flue gas denitrification systems, are used to clean industrial flue gases. The DeNOx process is used to remove nitrogen oxides (NOx).

The aim of the project was to optimize the inflow to the DeNOx catalytic converter in order to achieve better filtration.

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.
