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.
Claims15
A catalyzer for burning at least part of a fuel/oxidant mixture flowing through the catalyzer, the catalyzer comprising:
- several catalytically active channels;
- and
- several catalytically inactive channels;
- wherein, only in a longitudinal section of the catalyzer spaced apart from an inflow side of the catalyzer in a main flow direction of the catalyzer, the catalyzer includes one or more of the group of:
- turbulators arranged in at least several catalytically active channels and connections formed at least between several catalytically active channels and catalytically inactive channels, said connections enabling a flow between catalytically active channels and catalytically inactive channels.
A catalyzer for burning at least a part of a fuel/oxidant mixture flowing through the catalyzer, the catalyzer comprising:
- a plurality of catalytically active channels and a plurality of catalytically inactive channels, each channel having a first longitudinal portion upstream in a main flow direction of a second longitudinal portion;
- and
- one or more from the group of a plurality of turbulators and a plurality of connections,
- wherein the plurality of turbulators are arranged only in the second longitudinal portion of at least several of the catalytically active channels and the plurality of connections are formed in the second longitudinal portion between at least several catalytically active channels and catalytically inactive channels to operatively exchange a gas between the catalytically active channels and the catalytically inactive channels.
