Abstract
A heat exchanger includes a hollow heat exchanger main body that is enclosed in a radiant tube, and a heat conductor that is disposed on outer periphery of the heat exchanger main body. The heat exchanger performs heat exchange between a first gas flowing in between the radiant tube and the heat exchanger main body and a second gas flowing in hollow interior of the heat exchanger main body, and the heat exchanger comprises a turbulence flow generation promoting unit configured to promote generation of a turbulence flow from the first gas flowing in between the radiant tube and the heat exchanger main body, the turbulence flow generation promoting unit being disposed on the outer periphery of the heat exchanger main body without welding.
