COMPOUNDING CALCULATING DEVICE AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a compounding calculating device accurately predicting resistivity of mixed combustion ash by considering components of carbonized fuel and coal and their compounding ratio and of calculating a compounding ratio achieving the resistivity of the mixed combustion ash within an optimal range for dust collection by an electric dust collector during mixed combustion of the carbonized fuel obtained by carbonization treatment of sludge and coal in a coal-burning boiler. SOLUTION: The compounding calculating device includes: an ash resistivity prediction means for predicting resistivity of mixed combustion ash generated in mixed combustion of the carbonized fuel and coal by considering component analysis values of the carbonized fuel and coal and an ash resistivity decline ratio corresponding to the compounding ratio with respect to a reference ash resistivity set from resistivity of a mono-fuel combustion ash generated during mono-fuel combustion of coal; and a compounding calculating means for calculating the compounding ratio of the carbonized fuel and coal so that the predicted resistivity of the mixed combustion ash is within a management range by the electric dust collector.
