Title: Absorber tower metal hood to concrete shell attachment

Abstract: An assembly and method for facilitating the attachment of a metal alloy hood to the concrete shell of a spray absorber tower, and compensating for relative radial thermal expansion of the hood and the shell during start up, shut down, and operation of the spray absorber tower, while also providing accurate and effective distribution of shear forces circumferentially along a horizontal plane from the metal alloy hood to anchor rods partially embedded in the concrete shell of the spray absorber tower.
