Catalytic reactor and associated operating method

摘要

The device has a number of parallel channels extending from an inlet side (6) to an outlet side (7), whereby all channels are catalytically active, at least in a core region of a cross-section of the reactor (1), the catalytic activity of the channels is formed by a catalytically active coating on the channel surfaces exposed to the gas flow and the first channels in a first longitudinal section (8) containing the inlet side have a larger active surface components than second channels in a second longitudinal section (9) containing the outlet side. Independent claims are also included for the following: (a) a burner arrangement, especially for a gas turbine of a power generating system (b) and a method of operating an inventive catalytic reactor.
