Abstract
A steam generator with a heat exchanger in which the tube openings of the support plate are oversized relative to the outer diameter of the heat exchanger tubes, to facilitate assembly of the heat exchanger, and in which a positive contact preloading of the heat exchanger tubes in opposite directions is produced, once the steam generator goes to operating temperatures and pressures, by a mounting of the support plates which causes them to pull on the heat exchanger tubes in opposites directions so as to provide a passive, positive supporting of the heat exchanger tubes by the supporting plates which eliminates cross flow induced vibrations during operation, pressures despite the existence of clearance gaps between the heat exchanger tubes and the support plates through which they pass at ambient temperatures and pressures.
