摘要： Power-generation plant equipment (1) of the present invention is provided with a steam-flow-volume adjusting valve (20) that is provided in a superheated-steam pipe (30) on the upstream side of a steam turbine (7). During startup of the steam turbine (7), a controller of the power-generation plant equipment (1) increases a degree of opening of the steam-flow-volume adjusting valve (20) from a closed position, thus increasing the frequencies of the steam turbine (7) and an exhaust-heat-recovery generator (10); and, after the frequency of the exhaust-heat-recovery generator (10) reaches the frequency of a grid (40), the controller connects an exhaust-heat-recovery-side breaker (26) to supply power to the grid (40), and also sets the degree of opening of the steam-flow-volume adjusting valve (20) to a substantially fully-open position, thus, operating the steam turbine (7) depending on the frequency of the grid (40).

摘要： PROBLEM TO BE SOLVED: To provide an exhaust heat recovery device, which suppresses a decrease of chances for operating a Rankine cycle and permits an efficient operation of the Rankine cycle, in the exhaust heat recovery device provided with the Rankine cycle.SOLUTION: An exhaust heat recovery device 1 which recovers and uses exhaust heat of an engine 10 includes: a Rankine cycle 2 provided with a heater 22, an expander 23, a condenser 24 and a pump 25; a bypass channel 26 which circulates coolant around the expander 23; a bypass valve 27 which opens and closes the bypass channel 26; and a control unit 4. The control unit 4 executes a starting control of the Rankine cycle 2, in which the starting control actuates the pump 25 while opening the bypass valve 27 and, thereafter, closes the bypass valve 27. Also, when a pressure difference between the high pressure side and low pressure side of the Rankine cycle 2 after closing the bypass valve 27 does not attain a starting completion determination value within a predetermined time, the control unit 4 executes the starting control repeatedly.
