Passively cooled catalytic combustor for a stationary combustion turbine.

摘要

A catalytic combustor unit for a stationary combustion turbine includes a substrate (60) having a series of generally parallel passages (64) receiving a heated flow of fuel and air mixture with a catalyst coating applied on the wall surfaces of certain ones (64A) of the passages (64), whereas the others (64B) are free of the catalyst coating such that in the catalyzed passages the mixture is catalytically reacted and in the non-catalyzed passages the mixture provides for cooling of the substrate but upon discharge from these passages and mixing with the hot catalytically reacted gases is also combusted.
