Environmental Products


Fine Particle Screens

Fine particle screens remove fibrous particles such as refractory fibers and insulation fibers from the flue gas prior to reaching the Selective Catalytic Reduction (SCR) reactor, preventing particles from building up on the catalyst layers and causing a reduction in efficiency and NOx removal.

LPA Screens 

Large Particle Ash (LPA) Screens remove LPA, also known as popcorn ash, from the flue gas prior to reaching the Selective Catalytic Reduction (SCR) reactor. This prevents the rock-like particles from becoming lodged in the catalyst layers which can cause erosion and reduce NOx removal.

IGS Catflow screens and air cannon nozzles
CatFlow™ Screens

The IGS CatFlow screen system is designed to replace the catalyst screen located above the catalyst module. The screen improves safety during maintenance and inspection, saves time during installation and inspection due to its ease of handling, stops both combustion and non-combustion LPA from reaching the catalyst, and repels ash accumulation.
