  • Patent number: 6663379
    Abstract: The invention relates to a catalyzer for burning at least part of a fuel/oxidant mixture flowing through the catalyzer, in particular for a burner of a power plant installation. The catalyzer comprises several catalytically active channels and several catalytically inactive channels. A longitudinal section of the catalyzer is spaced apart from an inflow side in the main flow direction. In this longitudinal section turbulators are arranged in at least several catalytically active channels. In addition or alternatively, connections that enable a flow between the channels are formed in this longitudinal section between several adjoining channels.

  • Patent number: 6638055
    Abstract: A device for burning a gaseous fuel/oxidant mixture, in particular for a power plant installation, includes a catalyzer/swirl generator arrangement. Part of the fuel/oxidant mixture is burned in the catalyzer/swirl generator arrangement and the catalyzer/swirl generator arrangement generates a swirl flow. The catalyzer/swirl generator arrangement includes several flow channels, of which some are constructed catalytically active and others catalytically inactive. The flow channels can be arranged distributed around a longitudinal central axis of the catalyzer/swirl generator arrangement, and can be slanted relative to the axis.

  • Publication number: 20030031608
    Abstract: A catalyzer has a plurality of plane sheets arranged superposed and spaced apart from each other in a stack, between which a plurality of straight channels extend parallel in the flow direction and are delimited by the plane sheets. The plane sheets are coated in such a way that a catalytic coating is present in all channels; that the catalytic coating is limited to predetermined sections of the channels; and that inside the channels, uncoated sections in each case are positioned opposite to sections with the catalytic coatings. The uncoated sections absorb the heat radiation emitted by the catalytic coatings during operation, thereby improving cooling and preventing homogeneous ignition.

  • Publication number: 20020182555
    Abstract: A catalyzer for burning part of a gaseous fuel/oxidant mixture, in particular for a burner of a power plant installation, has catalytically active channels and catalytically inactive channels and at least two sectors are arranged consecutively in the main flow direction. The sectors include a first sector defining an inlet sector and at least one following sector that includes one or more of a mixing sector arranged downstream from the inlet sector and an outlet sector. Further, the catalyzer has one or more of a smaller flow resistance in the inlet sector than any following sector, a higher catalytic activity in the inlet sector than any following sector, a plurality of holes in the mixing sector oriented transversely to the main flow direction and through which adjoining channels communicate, and a swirl generator in the outlet sector that provides a swirl to a gas mixture flowing through the outlet sector.

  • Publication number: 20020155403
    Abstract: A catalytically operating burner with a catalyzer structure (4), useful in particular for a gas turbine system, has a heat-resistant carrier material (10) that forms the walls of several adjoining channels (13). The channels (13) pervade the catalyzer structure (4) in longitudinal direction and permit that a gaseous reaction mixture flows through the catalyzer structure (4). The walls are coated at least in part with a catalyst. In order to improve the catalytic conversion within the catalyzer structure (4), communicating openings (14) are constructed in the walls between an inlet end and an outlet end of the catalyzer structure (4). Adjoining channels (13) are able to communicate with each other through the communicating openings (14).
