Ceramic filter elements for filtering hot flue gases

Ceramic filter elements for filtering hot flue gases

TENMAT high-temperature ceramic filter elements are made of inorganically bound granular minerals, which provide greater strength than any other commercially available filter material. TENMAT hot gas filter cartridges are filter tubes developed for operating temperatures up to 1000 ° C.

TENMAT manufactures a wide range of element constructions from various refractory materials. TENMAT Candle (CS1150F) and Big Tube (CS1255F) ceramic filter rods are manufactured without asbestos and meet the highest worldwide emission standards. When using ceramic filter rods, it is not necessary to include expensive spark arresters or flue gas temperature reduction systems in the filtration system.

When using sorbentation, ceramic rods are suitable for removing a wide range of contaminants such as acids, bases, heavy metals, furans or dioxins.

The manufacturer states the expected service life of the filter rods of more than 6 years in continuous operation, without reducing the filtration efficiency.

The material for the production of filter rods is of natural origin, the used filter rods can be stored in a common landfill and it is not necessary to treat them as hazardous waste.

Material properties of filter tubes


  • Used for filtration of hot gases up to 1000 ° C
  • High filtration efficiency – usually 99.99%
  • Residual TZL drift usually below 1 mg / m3
  • The material is resistant to most chemicals
  • The material is resistant to thermal shocks
  • Regeneration using compressed air pulses Self-supporting design – no metal cage required
  • The material is completely non-flammable – fireproof and spark resistant
