Abstract

A boiler combustion control system (1) that outputs a fuel correction factor for correcting a load demand after feedback correction is provided. The system (1) includes: an arithmetic unit (14) that calculates the fuel correction factor based on a ratio of the load demand before and after the feedback correction, and an initial value/fine adjustment function that defines an initial value of a relationship between the load demand and a fuel charging amount; and a correcting unit (12) that outputs a reference curve correction factor for correcting the adjustment function. The correcting unit (12) calculates a deviation between a measured main steam-pressure and a set main one; acquires a cycle and an amplitude related to variation in the deviation; calculates the reference-curve correction factor based on a reference-curve correction function and outputs it; and corrects the correction function when the combination of the cycle and amplitude satisfies a predetermined condition. (Fig. 1)
