Abstract

PURPOSE: To make the promotion of efficiency of the operation, by automatically controlling a blast air quantity only with a release air control system, when a total suction air quantity still exceeds a required air quantity even for the suction air quantity of each blower reaching a minimum limit required for surging prevention.
CONSTITUTION: With a total suction quantity QBL of the blower becoming larger than an air quantity set value QS due to an increase of number of operational sets of the blower and a drop down of the air quantity set value QS, a regulator valve 11a, 11b is controlled toward a closing direction, simultaneously with an acceptance of the operation result of an operator 8 in the release air quantity control system becoming positive and a selector 15 feeding out an output signal, the setting is made to a release air quantity control meter 9. Then the control meter 9 controls a release air control valve 11c so that a release air quantity measured value, given by a transmitter 12c, may reach the set value. And when the total suction quantity QBL is still larger than the air quantity set value QS even for a suction air quantity lower limiter operating, only the blow air quantity control system automatically controls the blast air quantity.
