A heat exchanger according to the present invention is provided with bayonet tubes in its shell. One end of each of bayonet tube outer ducts is secured to and open at a tube sheet fixed at one end of the shell. One end of each of bayonet tube inner ducts is secured to and opened to a hot gas separation chamber. The other ends of inner and outer duct communicate with each other.Bayonettube Exchangers - Heat Exchangers - Buffalo Aug 29, 2020The bayonet tube is a smaller-diameter tube inserted into a larger-diameter tube that has been capped at one end. The fluid flow is typically entering the inner tube, exiting, hitting the cap of the larger tube, and returning the opposite direction in the annular area. The design eliminates any thermal expansion problems.
