High Temperature Ceramic Filters

When you need to remove pollutants and particulate matter, Glosfume high temperature ceramic filters have the edge at high and low temperatures:

  • Our ceramic filter elements are virtually 100% efficient in reducing particulate.
  • Glosfume filters are capable of high filtration of particulate down to sub-micron.
  • Standard carbon steel bodies allow continuous operation at up to 450 °C.
  • High performance alloy bodies allow further increase in operating temperature.
  • CFD modelling of high temperature operation optimises flow distribution for highly efficient dry flue gas treatment and prevention of dioxin reformation.
  • Our high temperature ceramic filters outperform bag filters and electrostatic filters.
  • Advanced control systems, using a virtual private network (VPN) enable filters to be monitored and adjustments made on-site or remotely from our office.
  • Glosfume systems are the only ones allowing maintenance or element changes without shutting the filter down.

Emissions performance

The combination of Glosfume high temperature ceramic filters and dry scrubbing with sodium bicarbonate (or activated carbon) can give the following typical emission results for carcass waste incineration directive (WID) and secondary aluminium smelting applications. These figures clearly show that our high temperature ceramic filters easily comply with current and future limits.

Carcass waste incineration directive (WID)

Determinand Post Filter WID Emission Limit % Below Limit
TPM 0.7 10 93
VOC's 0.8 10 92
HCI 1.4 10 84
SO2 4.9 50 91
CO 1.0 50 98
Dioxins 0.013 0.1 87

Note: All emissions are mg/m3 (11% O2, STP) except dioxins, which are ng/m3

Secondary aluminium smelting

Determinand Pre Filter Post Filter Typical Emission Limit % Below Limit
TPM 423 1.8 30 94
HCI 698 1.5 50 97
HF 0.19 <0.05 5 >95
CI 16.4 0.2 5 92
NOx 127 54 400 86
Dioxins 10 (estimate) <1 .01 >90

Note: All emissions are mg/m3 (as measured) except dioxins, which are ng/m3
