Industrial Flue Gas and Thermal Processing
Honeycomb SCR denitration catalyst and ceramic heat accumulation media for power generation, incineration, metallurgy and chemical process plants.
Industry Pain Points
What Makes This Application Hard
- NOx emissions from industrial flue gas have to be reduced to meet the permitted limits.
- Heat lost from furnaces and thermal processes has to be recovered by a heat storage and heat exchange medium.
- Media and catalyst have to survive thermal cycling and chemical corrosion in the flue gas stream.
