Abstract

PURPOSE: To preform a stable starting control of a concentrator by utilizing an output which is selected (by a lower-value selection circuit) from two outputs - an output of a ramp signal generation circuit, and an output of an arithmetic circuit which conducts operation on a deviation signal representative of the difference between the desired value and the actual value - for the control of vapor flow rate through the thickener.
