Abstract

PURPOSE: To eliminate a fault of a continuous operation of a condensate pump by detecting an operating state of a generator facility, judging a condensate flow rate of a necessary maximum limit according to its signal, and controlling a deaerator water level regulating valve so that the flow rate falls within this limited range. CONSTITUTION: A feed water flow signal 22 detected by a feed water flow transmitter 17 is input to a function generator 39. Here, a codensate flow rate set value at the time of its feed water flow rate is calculated and its signal is input to an adder 32. And, a deaerator tank water level signal 20 detected by a deaerator water level transmitter 15 is input to a control arithmetic unit 30. Here, a condensate flow rate set value is calculated, and its signal is input to an adder 32. The adder 32 adds the input condensate flow rate set value, and gives an optimum condensate flow rate set value to the arithmetic unit 38. A condensate flow signal 21 detected by a condensate flow transmitter 16 is input to the arithmetic unit 38, which outputs a control signal 23. This signal 23 is converted into a pneumatic signal 24, which is given to a deaerator water level adjusting valve 3 to control a condensate flow rate.
