Nitrogen oxide reduction (Nox)

Public familiarity with nitrogen oxides has increased since discussions began regarding the banning of diesel-powered vehicles. The lignite power stations operated by RWE achieved very low nitrogen oxide emissions (NOx) quite some time ago as a result of optimum combustion.

Research & Development by RWE supports the further refinement of the state of the art with regard to reducing emissions, and by setting up operational-level trial systems, RWE is testing opportunities to further reduce NOx emissions in flue gas from its fleet of power stations. At the same time, this forward-looking approach serves to observe future limitations that may arise from the European BREF LCP process.

The opportunities to reduce NOx emissions via both primary and secondary measures are being investigated in this connection.

These trials are giving the manufacturers valuable insights for further refinements to these systems. It is not currently clear, however, when it will be possible to use catalysts of this nature in the flue gas train of lignite power stations.
