PURPOSE: A control device of a damper actuator of a boiler and a control method thereof are provided to improve the efficiency of the boiler, and to extend the life span by evenly supplying combustion air into the combustion chamber and forming flames in the center without leaning. CONSTITUTION: A damper actuator control device of a boiler is composed of a damper actuator(13) rotating a damper by converting electric signals from a control line(15) into the pneumatic signal, a limit switch(20) outputting the feedback signals according to the position of the damper, and a control unit controlling the damper actuator based on the feedback signals from the limit switch. The damper actuator is composed of a damper shaft rotating the damper, and an actuator directly mounted to the damper shaft. The damper actuator is controlled accurately by the electric signal of 4 to 20 mA through the control line, and the reliability is improved by directly receiving the feedback signal from the limit switch.
