<p>A lug (30) for attachment to a waterwall (11) and for supporting a load on the waterwall (11) which is a part of steam generation apparatus (10) and which includes a web shaped metal plate formed in a generally arch shape. The arch shape has first and second legs (32, 34), each of the legs (32, 34) being dimensioned and configured for engagement with a part of the axial extent of respective associated tubular members (20) in an associated waterwall (11). In some forms of the invention each of the legs (32, 34) includes a generally planar portion and each of the legs (32, 34) has an axial extremity that is rectilinear. The axial extremity of each leg (32, 34) that is rectilinear may be disposed within the generally planar portion of the leg (32, 34). The lug (30) may be fabricated from a single piece of metal and the generally planar portions in respective legs (32, 34) are disposed in respective planes that intersect at an angle that is less than 90 degrees or even 30 degrees. In still other embodiments of the invention the generally planar portion is disposed in respective legs (32, 34) of the lug (30) that are mutually parallel.</p> |
