Abstract
A heat exchanger having coaxial inner and outer conduits is characterized by a flow intercepting body which extends into the inner conduit to thereby divide the length of the heat exchanger into two sections with different heat exchange characteristics. Adjustment of the temperature of gases exiting the heat exchanger may be accomplished by varying the ratio of the lengths of the two sections of the heat exchanger.
