Abstract

PURPOSE:To reduce the cost and weight of an air preheater and achieve high temperature efficiency, by a method wherein the upper and lower ends of a thin corrugated plate type bulkhead, employed for a heat exchanging body, are connected to wax stagnating grooves provided on a flow passage bulkhead. CONSTITUTION:The upper and lower ends of a thin corrugated plate type bulkhead 2, constituting a heat exchanging body, are put on a flow passage bulkhead 10 equipped with wax stagnating grooves to braze them in a furnace by brazing material whereby an air preheater is assembled. Accordingly, the preheater can be assembled as a vessel; therefore, the manufacturing cost of the same may be reduced. Further, since a thin plate is employed, the weight of the whole of a device may be reduced. Furthermore, the heat exchanging surface of the air preheater is constituted of the corrugated structure and heat exchange between combustion gas and air is effected directly by the corrugated thin plate without any fin or the like; therefore, heat permeating rate may be increased and a high temperature efficiency may be achieved.
