Tube-bundle heat exchanger with a non-condensable gas removing arrangement

摘要

Heat exchanger having an essentially cylindrical housing, at the top of which are arranged the inlet and outlet for the feedwater and the steam inlet, and at the bottom of which the condensate outlet is arranged, and having a tube bundle which is wound onto a central tube running from top to bottom and in the middle of the housing. At least one tube (20) open at the bottom is arranged on the central tube (21), which in the region of the condensation zone has at least one opening (22) into the interior of the housing (10) and is led out (23) of the housing in order to be able to remove non-condensable gas. The central tube (20) is constructed as a supply for the feedwater into the inlets of the tubes of the tube bundle. IMAGE
