Abstract
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. A hot gas separation chamber is provided inside the tube side pressure drum which is attached to and in contact with the tube sheet. Such construction of a heat exchanger according to the invention as this prevents thermal stress from arising, rendering the design of economical and reliable heat exchangers possible.
