Abstract
A catalytic combustor (28) includes a plurality of concentric tubular pressure boundary elements (46). The pressure boundary elements are arranged to form a first annular space (e.g., 50) conducting a first fluid flow (e.g., 60) and a second annular space (e.g. 49), separate from the first annular space, conducting a second fluid flow (e.g., 58). A catalytic material (32) is disposed on a surface (e.g., 64) of at least one of the pressure boundary elements and exposed to at least one of the fluid flows.
