Abstract: In an apparatus for heating high-temperature air for use in recovering, by heat exchange, the heat of an exhaust gas of elevated temperature generated from an apparatus for disposing of wastes, prolonged service life, improved working efficiency, improved efficiency of heat recovery on heat exchange are attainable with least thermal deformation and reduced dust deposition. Solving Means In the apparatus for heating high-temperature air located in a gas atmosphere of elevated temperature, an air to be heated and caused to flow through a heat transfer conduit is heated upon heat exchange with the gas of elevated temperature. The heat transfer coduit is constructed with a heat transfer pipe in which the air to be heated is flowed, and a refractory protective pipe held in coaxially covered relation to the heat transfer pipe with a gapping defined between both pipes. The refractory protective pipe is formed to be angular when seen sectionally, and the heat transfer pipe is disposed in a plural number and secured in face-to-face contact with adjoining heat transfer pipes and one sectionally angular face of the refractory protective pipe.
