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.
Claims18
A device for burning a gaseous fuel/oxidant mixture, comprising:
- a flow-enabling catalyzer/swirl generator arrangement in which part of the fuel/oxidant mixture is burned and which generates a swirl flow, wherein the catalyzer/swirl generator arrangement comprises several flow channels which are continuous through the whole catalyzer/swirl generator arrangement, some of said flow channels being constructed catalytically active, and the others of said flow channels being constructed catalytically inactive, wherein the flow channels are arranged distributed around a longitudinal center axis of the catalyzer/swirl generator arrangement that extends in the main flow direction of the catalyzer/swirl generator arrangement, and the flow channels are slanted in relation to the longitudinal center axis of the catalyzer/swirl generator arrangement in such a way that the longitudinal directions of the flow channels each extend slanted in relation to a straight line that extends parallel to the longitudinal center axis of the catalyzer/swirl generator arrangement.
A catalyzer/swirl generator arrangement for a device for burning a fuel/oxidant mixture in a power plant installation, wherein the catalyzer/swirl generator arrangement is constructed so that the fuel/oxidant mixture is able to flow through it, and the fuel/oxidant mixture is provided with a swirl when flowing through the catalyzer/swirl generator arrangement and is partially burned, wherein the catalyzer/swirl generator arrangement comprises several flow channels which are continuous through the whole catalyzer/swirl generator arrangement, some of said flow channels being constructed catalytically active, and the others of said flow channels being constructed catalytically inactive, wherein the flow channels are arranged distributed around a longitudinal center axis of the catalyzer/swirl generator arrangement that extends in the main flow direction of the catalyzer/swirl generator arrangement, and the flow channels are slanted in relation to the longitudinal center axis of the catalyzer/swirl generator arrangement in such a way that the longitudinal directions of the flow channels each extend slanted in relation to a straight line that extends parallel to the longitudinal center axis of the catalyzer/swirl generator arrangement.
A method for burning a fuel/oxidant mixture in an application including in a power plant installation, comprising:
- providing a catalyzer/swirl generator arrangement wherein the fuel/oxidant mixture is provided with a swirl and is partially burned catalytically before being fed into a combustion chamber, wherein the catalyzer/swirl generator arrangement comprises several flow channels which are continuous through the whole catalyzer/swirl generator arrangement, some of said flow channels being constructed catalytically active, and the others of said flow channels being constructed catalytically inactive, wherein the flow channels are arranged distributed around a longitudinal center axis of the catalyzer/swirl generator arrangement that extends in the main flow direction of the catalyzer/swirl generator arrangement, and the flow channels are slanted in relation to the longitudinal center axis of the catalyzer/swirl generator arrangement in such a way that the longitudinal directions of the flow channels each extend slanted in relation to a straight line that extends parallel to the longitudinal center axis of the catalyzer/swirl generator arrangement.
