<p>A liquid distributing device for use in the upper end of an upright tube in a vertical, tubular heat exchanger, which device comprises a ferrule having a head adapted to seat upon the upright tube, a cylindrical sleeve adapted to fit snugly within said tube, a bore in said head, and means to distribute liquid from said bore onto the inside surface of said cylindrical sleeve and then onto the inside surface of the upright tube as a falling film, whereby erosion of the tube by impingement of liquid thereon is minimized. Means are also provided to prevent building of scale within the ferrule.</p> |
