Abstract
An erosion resistant waterwall in which a plurality of erosion resistant stud members are attached to the exposed surface of a waterwall consisting of a plurality of spaced water tubes connected together by continuous fins. The size of the stud members relative to the tubes are such that a plurality of the stud members extend around the periphery of each exposed tubes surface in a spaced relationship in a direction perpendicular to the axis of each tube. The stud members may be in the form of steel balls or small rod members attached to the exposed surface, and a ceramic sleeve can extend around the rod members.
