Abstract
A heat exchanger is comprised of two heat exchanger sections, at least one of which is provided with a floating header to accommodate differential thermal expansion. The two heat exchanger sections are enclosed by an inner shell wall, and an external connecting passage is provided outside the inner shell wall, through which one of the fluids flows between the two heat exchanger sections. The external connecting passage is enclosed by an outer shell. The inner wall is provided with openings which communicate with the external connecting passage. The openings may be in the form of a substantially continuous gap or discrete openings. Specific examples of heat exchangers with this construction include a steam generator, a steam generator and combined catalytic converter, and a water gas shift reactor.
