Definitions
- a support structure comprises wires, these are preferably thicker than the fibers / wires of the filter material and preferably have a thickness of more than 100 ⁇ m, preferably more than 200 ⁇ m, but preferably less than 1000 ⁇ m, in particular less than 700 ⁇ m.
- FIG. 3 shows a schematic view, partially shown in section, of a filter device for filtering in a process gas
- An energy input source 70 designed as a radiant heater is provided here as the means for initiating the oxidation reaction, which couples its heat radiation into the filter chamber 40 via a transparent area 42 and absorbs it to a large extent from the particles 51 entrained in the process gas 50, so that these are heated in a targeted manner .
