PROBLEM TO BE SOLVED: To provide a boiler fuel input determination device capable of verifying whether or not a ratio target set in a boiler fuel reducing system is optimal and automatically changing the ratio target.SOLUTION: There are provided data number distribution confirmation/standard deviation evaluation means 34, 35to 35, 36to 36, 37, 38 for confirming a distribution of the number of pieces of data of a ratio Ki between input requirement steam amount A and requirement steam amount B for every renewal time and at the same time evaluating either fuel charging amount Fueli or main steam pressure Pi in reference to the standard deviation for every renewal time; and state determination means 39 for determining whether or not a ratio target set in a boiler fuel reducing system is optimal in reference to a result of evaluation by the data number distribution confirmation/standard deviation evaluation means, determining a corrected ratio Goiii for changing the ratio target upon determination that the ratio target is not optimal and inputting the determined corrected ratio Goiii into fuel correction coefficient calculation means 15, 16 in place of the ratio Ki. |
