気圧力制御装置。In a combustion furnace that has a control valve that adjusts the amount of air from a blower, a signal related to the control valve opening is input, and a valve opening signal that is slightly smaller than the controllable limit opening of the control valve is set as the set value. The controller includes a primary controller and a secondary controller that uses the output of the controller as a set value to adjust the air pressure on the output side of the blower using the rotational speed of the blower and/or the damper valve on the input side of the blower. Air pressure control device in combustion furnace.
