Extreme high-temperature resistance
Extreme high-temperature resistance
Porous ceramic-fiber element for high-temperature flue-gas dust removal and optional integrated catalytic treatment.

Hot gas filter, also named ceramic fiber filter, is a porous sintered filter element specially developed for high-temperature flue gas working conditions. It adopts vacuum forming and high-temperature curing to form a gradient porous fiber structure that removes fine particles such as PM2.5 and PM10. Non-catalytic elements remove solid dust, fume and soot; catalyst-coated elements combine dedusting, denitrification and dioxin decomposition in one unit.
