SHELL-AND-TUBE HEAT EXCHANGER, PACKAGE FOR SHELL-AND-TUBE HEAT EXCHANGER, APPLICATION OF SHELL-AND-TUBE HEAT EXCHANGER (OPTIONS)

摘要

The invention relates to a shell and tube heat exchanger wherein, in order to enable uniform gas distribution in the flow around the tube bundle, a tube bundle, consisting of a plurality of tubes having at least one tube base, which is delimited to the outside by a shell surface and has a longitudinal axis extending centrally in the shell space, is arranged in a shell space, wherein the arrangement of the tubes in the tube bundle defines a tube area, which has an inner channel around the longitudinal axis which is free of tubes and an outer channel between the outer edge of the tube bundle and the shell surface which is free of tubes, wherein, according to the invention, the tube area has at least one connection zone between the inner and outer channel through which fluid enters into and/or exits from the shell space during operation of the shell and tube heat exchanger.
