Abstract: PURPOSE:To control stably the process quantity for boiler against a rapid change in load by limiting the rate of change in the input instruction signals to boiler to a rate not to exceed the rate of change that is beforehand set and outputting it to a sub-loop control means. CONSTITUTION:If input instruction signals (BID) 13 to boiler that are outputted from a boiler master section 11 changes more than an allowable rate of change for the boiler, a deviation develops between the value of input instruction signal to boiler on the input side of a rate of change limiting device 13-1 connected to the output side of the boiler master section 11 and the value of input instruction signal to boiler on the output side of the rate of change limiting device 13-1. That deviation is detected by a limitation detector 13-2, and if it is larger than a value beforehand set, it is judged that the rate of change limiting device 13-1 has operated. Further, when the main steam pressure 12 that is detected by a main steam detection device 12-1 goes over a rated value by a certain value, the limitation detector 13-2 outputs opening signal to the drive sections of a primary superheater bypass valve 24 and secondary superheater bypass valve 25 to open both of them.
