制御装置。 In a coal dryer that uses exhaust gas, there is a coal temperature controller that controls and calculates the deviation between the measured value of the coal outlet temperature and the coal temperature set value, and a coal temperature controller that controls and calculates the deviation between the measured value of the exhaust gas outlet temperature and the set value of the exhaust gas temperature. a low selector that selects the lower of the operational output of the coal temperature controller and the operational output of the exhaust gas temperature controller, and a damper means at the exhaust gas inlet that is operated by the output of the low selector. Temperature control device for coal dryer.
