STEAM GENERATOR WITH A HORIZONTAL BUNDLE OF HEAT EXCHANGE TUBES AND METHOD FOR ASSEMBLING SAME

摘要

A steam generator with a horizontal bundle of heat exchange tubes comprises a welded cylindrical housing made from steel shells and provided with at least a connecting pipe for supplying feed water and a connecting pipe for removing steam as well as two ellipsoidal ends, devices internal to the housing, and an inlet collector and an outlet collector, which are connected to a bundle of heat exchange tubes that forms a heat exchange surface of the steam generator, wherein the inside diameter of the steam generator housing is selected on the basis of the claimed relationship. The steam generator housing is filled from the bottom up with the tubes of a heat exchange bundle to a height not greater than three quarters of the inside diameter of the housing, wherein the remaining space of the upper part of the steam generator housing can be used for drying steam. The technical result is the creation of a steam generator that requires less metal and provides for the drying of the produced steam in a single housing with a heat exchange surface.
