PURPOSE: A method for estimating a heating value of pulverized coal for blast furnace injecting is provided to estimate the heating value of the pulverized coal accurately and simply and to predict the heating value of the pulverized coal per positions where the pulverized coal is stacked according to stacking properties. CONSTITUTION: A method for estimating a heating value of pulverized coal for blast furnace injecting is as follows. Influence factors which are highly related to the heating value of the pulverized coal are selected as independent variables so that the heating value of the pulverized coal is estimated. The independent variables are obtained through a collecting step, a determination coefficient calculating step, and a selection step.
