Ceramic Filters

Filter Designs has a long and proven record of supplying hot gas ceramic filters for a variety of applications which involve high temperatures (250 – 1000°C). Some example of industries where we have applied this technology includes:

  • Soil Reclamation
  • Clinical Incineration
  • Pharmaceutical Waste
  • Animal Rendering Incineration
  • Straw Burning
  • Wood Burning
  • Biomass Wood Fired Boilers
  • Coal Gas Incineration
  • Gasification
  • Pyrolysis
  • Oil Refinery Waste

A ceramic filter is an ideal solution when high temperatures are involved, although they offer challenges which a bag filter does not. The ceramic media from any of the suppliers below can reach and exceed 1000˚C but consideration has to be given to the materials of filter construction and the impact of temperature. Stainless 316 and stainless 310 are options which offer no fabrication issues but do come at higher costs when compared with mild steel. A ceramic filter using candles at these temperatures requires specific design changes to account for expansion, heat transfer to the pulse control system and any adjoining staircase, CAT ladder, ducting cantilever support or other metallic connection. Filter Designs use a ceramic based heat break material to stop the heat transfer. At these high temperatures, options such as offline cleaning require valves with externally mounted ‘outrigger’ bearings and tolerances suited to the temperature range. The ID fans, ducting, differential pressure monitoring devices, pulse control, screws and rotary valves, insulation and cladding in these systems all have to be designed to accommodate the elevated temperatures.

We have incorporated various suppliers and sizes of filter elements into our designs, and these include:

  • Glosfume elements
  • Clean Edge (Cerafil)
  • Tenmat
  • Brightcross

Ceramic elements can be supplied in different sizes to suit the gas volume and application. The filters can be incorporated into our CleanPulse range of reverse jet (pulse jet) ceramic filters and they can also be tailor made to fit your exact requirements so that they suit your application perfectly. FDL can design a filter to be tall, long, thin, wide, to suit almost any site restriction.
