<p>PROBLEM TO BE SOLVED: To provide a mill temperature control method capable of preventing a spontaneous combustion of a biofuel by controlling the inner temperature of a mill.SOLUTION: A mill temperature control method for a mill in which a mixture of coal and a biofuel and coal alone are pulverized temporally comprises: a flown-out air temperature measuring step to measure the temperature of air flown out from the mill; and a monitoring step to monitor the temperature of the air flown out from the mill. The monitoring step permits the temperature of the flown out air measured in the flown-out air temperature measuring step when the mixture of coal and the biofuel is pulverized to be lower than the temperature measured in the flown-out air temperature measuring step when the coal alone is pulverized.</p> |
