Abstract
The steam impingement cooling and retrieval system for turbine shrouds includes a plurality of circumferentially spaced housings about a turbine shroud, each housing being divided by an impingement plate defining first and second chambers on opposite sides of the housing. Steam supplied into a first chamber passes through a plurality of apertures formed in the impingement plate into the second chamber for impingement cooling of the shroud surface forming the opposite wall of the housing. Post-impingement steam passes from the compartment into a manifold for flow through and exhaust passage. In one form, a plurality of compartments are formed in the impingement plate. A first set of the plurality of compartments include through apertures for delivering steam from the first chamber into the second chamber. The second set of compartments communicates only with the second chamber and an exhaust passage whereby post-impingement steam passes from the second chamber through apertures of the impingement plate into the second set of compartments for flow to a manifold at the end wall of the housing for delivery to the exhaust passage.
