Abstract
A steam generator having a steam drum and which includes first and second U-shaped members dimensioned and configured for cradling the steam drum. Each of the first and second U-shaped members has first and second elongated leg portions and each of the leg portions is supported by a separate first body. The first body is supported by a separate second body, one of the bodies has a concave spherical section face and the other has a convex spherical section face, the concave spherical section face and the convex spherical section face are disposed in abutting load bearing relationship. Thus, a discrete set of first and second bodies is associated with each of the leg portions.
