Abstract
PURPOSE: To improve follow-up characteristic of fuel flow rate control, by making such an arrangement that a burner head pressure control region is provided in a region where burner head pressure is capable of operating, and when the burner head pressure entered the pressure control region, correction is done by operating a fuel flow rate adjusting valve at the same pressure.
CONSTITUTION: When controlling a fuel flow rate adjusting valve VFC and a pressure adjusting valve VPC, set values for upper limit and lower limit of burner head pressure are calculated by function generators 301 and 302 on the basis of fuel flow rate demand signal (FRD). Thus calculated values are put out to low-value-and- high-value selecting circuits 302 and 304 which put in burner head pressure PBH, and output of the circuit 304 is reduced 305 to the aforementioned pressure PBH. Output of a reducer 305 is added 307 to FRD through a proportionater 306, and then, it is reduced 308 to VFC flow rate signal FVFC and controls the valve VFC in accordance with the output. After VPC, a deviation between a pressure set value PPCR and an actual measurement value PPC is added 312 to FRD, and then, the output is reduced 313 by VPC flow rate signal FVPC, and the valve VPC is controlled in accordance with the output.
