in which combustion takes place in the presence of catalytic material

Methods or apparatus, e.g. incinerators, specially adapted for combustion of specific waste or low grade fuels, e.g. chemicals > of waste gases or noxious gases, e.g. exhaust gases > in which combustion takes place in the presence of catalytic material

Incinerators or other apparatus for consuming industrial waste, e.g. chemicals (incinerator closets A47K11/02; oxidation of sludge C02F11/06; burners in general, burner details F23D; incinerating radioactive waste G21F9/00) > of waste gases or noxious gases, e.g. exhaust gases (exhaust apparatus for engines with means for rendering the exhaust innocuous, e.g. by thermal or catalytic conversion, F01N3/08; combustion of uncombusted material from primary combustion within apparatus for combustion of solid or fluent fuel F23B, , F23C) > in which combustion takes place in the presence of catalytic material
