  • EP 1 353 125 A1 or EP 1 985 929 A2 shows where in addition to the built-in particulate filter outside the actual firebox and a Abgasumlenkplatte and an additional ventilation duct are installed. The pollutants are not degraded in this case, but the exhaust gases diluted with fresh air.
  • the problem is that substantially only the content of particulate matter reduced, but the content of highly toxic carbon monoxide is not or only insufficiently reduced. Some processes even run the risk of increasing the carbon monoxide content.
  • the method according to the DE 102 15 734 A1 provided an additional electrical heating for the combustion of soot particles deposited in the ceramic network to heat the ceramic network to above the ignition temperature of the pollutants. Under these conditions, however, predominantly carbon monoxide and not carbon dioxide.

  • the catalytic coating of these other metal oxides is optionally formed with mixing with other metal oxides.
  • the filter used is preferably a non-combustible foam filter.
  • Foam filters are understood as meaning filters which have a foam or sponge-like structure with pores.
  • the foam filter is open-pored.
  • Such a foam filter can be easily flowed through by the heating gas with only slight pressure losses. Due to the high surface an efficient cleaning takes place.
