Homogeneous gas distribution at the SCR inlet permitted dispensing with the metallic grid (dummy layer). This results in lower investment and operating costs.

The combination of the SCR with an already exisiting SNCR is being successfully utilised in Mergelstetten.

The high flue gas temperature creates a sticky dust environment. Our tailored solution has been operating under these conditions since May 2010.
