Abstract
PURPOSE:To enable stable operation of a generating plant by cutting off the flow of a secondary medium to at least some preheater of plural preheaters as heat exchangers for preheating the secondary medium to be passed through a by-path. CONSTITUTION:While the secondary medium 10 is passed from the first preheater 8 to the sixth preheater 3, it is subjected to energy of hot water 1 to be preheated and changed into high-temperature and high-pressure vapor by an evaporator 2 to drive a turbine 11 and rotate a generator 12. Now, if the flow rate of hot water 1 is remarkably lowered than a design point, when the difference between the decreased heat exchanger duty and the heat exchanger duty decreased at the evaporating portion 2 is larger than the heat exchanger duty of the first preheater 8, according to a control signal from an arithmetic unit, a control valve 20 is closed and a control valve 24 is opened. The secondary medium 10 is passed through a by-pass line 22 not to be heat- exchanged at the first preheater 8. Accordingly, at the sixth preheater 3, the evaporation of the secondary medium can be prevented to avoid pressure change in the secondary medium system and an increase in pressure loss, so that the generating plant can be operated stably.
