Abstract
A heat transfer element for cross flow heat exchanger consists of ceramic corrugated and planar plates. A plurality of the heat transfer elements are stacked up in such a manner that the direction of corrugation in adjacent elements intersects at right angles to form a heat transfer block for cross flow heat exchanger. Concave portions of corrugation, which confront soot-blowing flow for removing soot deposited onto the heat transfer surfaces of heat transfer block, are filled with ceramic solids. Also concave portions of corrugation corresponding to the corners, which abut the packings attached when the heat transfer block is installed on a casing, are filled with ceramic solids.
