Abstract
PURPOSE:To reduce fatigue of apparatus due to thermal stress by detecting the distribution of temperatures in apparatus for use in a turbine to calculate the thermal stress in apparatus based on detection signals, and controlling main steam temperatures so as to restrict the thermal stress to a preset value. CONSTITUTION:A high-temperature steam generated in a boiler 1 is introduced through a main steam stop valve 2 and a main steam control valve 3 into a main steam turbine 4 after it is supplied to a final heater 17. On the other hand, a steam finished its work in the steam turbine 4 is again supplied to the boiler 1 by a condensate pump 8 after it is condensed in a condenser 7. In this case, the temperature on each internal and external surface of each valve 2, 3 is detected by each temperature detector 10a, 10b, and the detection signals are inputted through each subtracter 11a, 11b to a control device 12. The temperature in the steam turbine is also detected by a temperature detector 10c, and the detection signal is inputted to the control device 12. Further, the control device 12 controls a bypass feed water flow control valve 16.
