Abstract
A modular catalytic combustor for a gas turbine has a plurality of individual, non-metallic cylindrical catalyst beds, and a support structure for each of the individual catalyst beds. Each catalyst bed together with its support structure forms an individual catalyst module. Each support structure includes an outer cooled support cylinder, with the individual support cylinders of the various modules interconnected in spaced relationship with cooling air passageways between. There are means for supplying compressed air, such as from a gas turbine compressor, into the space surrounding the support cylinders. The outer cooled support cylinders are provided with apertures for entry of cooling and purge air from the surrounding space. Each of the catalyst beds has an integral, cylindrical, outer ceramic shell, and is positioned within a corresponding outer support cylinder. A sheet metal heat shield is interposed between and concentric with each of the outer support cylinders and the catalyst bed within. The heat shield is mounted and configured so as to provide passageways for cooling and purge air such that a limited amount of cooling and purge air enters through the apertures and flo…
