Abstract

PURPOSE: To perform optimum throttling control by obtaining a fuel throttling rate according to either the load requirement or the number of burners.
CONSTITUTION: An adder 51 receives a flow-rate demand signal 16 or throttling starting flow-rate Q3, and through the subtraction of mark throttle flow rate Q0 from the throttling starting flow rate, a differential signal 52 or Q3-Q0 is generated. The adder receives a burner quantity signal 21 or burner-cut starting quantity ni, and through the subtraction of the number no of burner-cut ending from the burner-cut staring quantity, the difference is multiplied by the burner-cut interval T0, and further the inlet valve operating time Ti is added, and then a signal 54 or (ni-n0)To+Ti is generated. Throttle rate R=(Q3-Q0)/(ni-n0)To+Ti is generated in a division calculatior. Said output is applied to an analogue memory 57, and a variation rate setting signal 19 is generated
