Abstract

PURPOSE: To enable prevention of overheat without raising allowable minimum load by operating a water ejector when a turbine load is below a set value or the temperature of an exhaust hood is above the allowable value, in a water ejector of a turbine exhaust hood.
CONSTITUTION: A signal of a turbine load detector 21 and a signal of a turbine low pressure exhaust hood temperature detector 23 enter a selector 25. An open signal is issued when a load signal is below a set value or a temperature signal is above a set value, and cooling water 9 is ejected in the exhaust hood out of nozzle 13. In other words, a water ejection control 10 is operated by a turbine load from starting time up to the set load, and water is ejected irrespective of temperature in the exhaust hood. And it is controlled by the exhaust hood temperature when it exceeds a load control limit.
