ABSTRACT:
A method and apparatus for forming an array of multiple parallel flow orifices, for example by holes drilled through a plate in a selected pattern and spacing and of selected sizes or flow diameters, and whereby these orifices are used to provide an approximately equal and adequate distribution of liquid flowing through them as parallel streams of liquid and into an evaporation zone or a parallel array of evaporation channels, and wherein the orifices can be adjusted in flow diameter to control the flowrate of liquid in generally parallel streams with an array of orifice adjusting apparatus, for example an adjacent sliding orifice plate which provides for orifice flow rate adjustment with orifices through this second plate corresponding in position to those of the first orifice plate, and the use of such dual orifice plates for supporting a pool of liquid there-above and for controlling the flowrate of liquid through the first array of orifices by reducing or enlarging their orifice flow diameters to control the level of the liquid in the pool or the pressure of this pool on or at the orifices and controlling the effect-to-effect pressure causing flashdown, and to improve the evaporation process or the degree of evaporation in an adjacent flash evaporation zone or in a bundle of adjacent evaporator tubes, and when applied to a multi-effect series of several such vertical tube evaporators.
