ABSTRACT:
A device is provided for heating liquids, slurries and the like by direct condensation of steam. The device consists of a vertically oriented, substantially cylindrical elongated vessel, wherein liquid to be heated is introduced at the top and the heated liquid is removed at the bottom. The device is provided with at least one liquid treatment zone consisting of a perforated tray placed perpendicular to the downward flow of the liquid, a downwardly conveying cone-shaped underflow located below the tray and a hemispherical impingement surface positioned below the opening of the cone-shaped underflow. Steam is introduced in the zone at a point where the liquid exits from the underflow. This arrangement allows a maximum degree of heat exchange between the steam and the liquid without causing "hammering" due to excessive steam condensation.
