ABSTRACT:
A forced circulation evaporator and method of use is disclosed that make use of a rotating impeller to both circulate liquid past the heating surface of the evaporator and to effect separation of liquid from vapor. A plurality of passage tubes acts as a generator of a liquid-vapor mixture. The impeller provides centrifugal force vectors to propel the liquid entity against the side wall of the separation zone to thereby leave the vapor to egress from the separation zone at a point near the axis of said impeller. Thus, the centrifugal force acts upon the varying densities of liquid versus vapor to cause separation more rapidly than under the mere influence of gravity.
