Coal selection support system and coal selection support program

摘要

A coal selection support system and a coal selection support program capable of supporting selection of a plurality of types of coal to be mixed and setting of mixing ratios of a plurality of coals from more concrete and less data than before provide. When the type of coal to be mixed and its mixing ratio are provisionally selected in the provisional selection task (43), the correction coefficient calculation task (44) calculates the correction item value DB (21) and the correction coefficient DB (22) Calculates a mixed coal capacity correction coefficient for correcting fluctuation in the amount of pulverization occurring in the mill when pulverizing a plurality of coals based on the data of the maximum rated grinding amount of the mill and , A mixed coal capacity correction coefficient, and a predetermined load factor of the mill, the mixed coal pulverization amount capable of pulverizing a plurality of coals when the mill is operated at a predetermined load factor is calculated. The judgment task (46) judges whether a plurality of provisionally selected coals can be operated based on the mixed coal pulverization amount.
