  • Method for controlling solid particle flow in an evaporator
    Patent number: 5474653
    Abstract: A method for use in an evaporator for selectively controlling the flow of solid particles within the evaporator. The method provides for the separation of solids from a liquid through the use of a separation chamber having a plurality of apertures, each of which has a critical size. In the separation chamber, solid particles which are larger than a critical size are separated from the remainder of the solution. The separated particles exit the separation chamber via a bypass conduit for circulation directly to the sump of the evaporator for recombining with the separated liquid portion which passed through the separation chamber and was subsequently concentrated in the heat exchange tubes. The method prevents solid particles from clogging the system and allows for continuous circulation of the solution and solid particles.
