Typical Operation

Flue gas 380-400°C
  180.000 Nm³/h
Dust 80-90 g/Nm³
Layers 4 in operation
NOX,in 1100-1300 mg/Nm³
NOX,out 200 mg/Nm³

Homogeneous  gas distribution at the SCR inlet has made it possible to dismantle the metallic grid (dummy layer) without any negative impact on reliability and performance. The result is a reduction in investment and operating costs.

SCR is combined with an already operational SNCR installation.

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

Proven reliability and uninterrupted long-term operation with dust cleaning tailored to cement applications.

Catalyst performance is essential for a economical long term operation. The oldest catalytic elements have been in operation without requiring regeneration for 3 years.  Since lifetimes can be extended through multiple regenerations, this is truly an economically attractive solution.
