ABSTRACT:
The flow of air into a catalyst regenerator is automatically controlled by controlling a side air stream responsive to a computed desired total air flow signal and by controlling a main air stream at a constant value. This constant value is changed if two conditions simultaneously occur: The time elapsed since the last change of said constant value is not shorter than a given minimal value, and the control of the side air stream exceeds the limit of the side air controller.
