Abstract
A catalytic combustor unit for a stationary combustion turbine includes a substrate composed of a plurality of intersecting walls defining a series of generally parallel passages aligned in rows and columns, open at their opposite ends and exposed to a heated flow of fuel and air mixture therethrough. The walls have sections which border and define the respective passages. Each wall section is in common with two adjacent passages and has a pair of oppositely-facing surface regions, one of which is exposed to one of the two adjacent passages and the other exposed to the other of the two adjacent passages. A catalyst coating is applied on selected ones of the wall surface regions exposed to certain ones of the passages, whereas selected others of the wall surfaces exposed to certain others of the passages are free of the catalyst coating. The substrate is thus provided with an arrangement of catalyzed passages in which the mixture is catalytically reacted and non-catalyzed passages in which the mixture is substantially not reacted but instead provides passive cooling of the substrate.
