Abstract

PURPOSE: To prevent the turbine from being overheated regulating a cooling steam flow in a turbine high pressure part by a method wherein a cooling steam regulating valve is fitted in a cooling steam duct which couples the high pressure part and low pressure part of the turbine, and a temperature detector is disposed in the high pressure part.
CONSTITUTION: The cooling steam regulating valve 8 is fitted in the cooling steam duct 9 coupling the high pressure part 6 and low pressure part 4 of the turbine. The temperature detector 15 is installed in the high pressure part 6 to cause the steam regulating valve 8 to be opened and closed. Thus, since the cooling steam flow is regulated according to the temperature in the high pressure part 6, waste of the steam can be prevented and further, loss of the turning force can be reduced as well. In addition, the overheat of the high pressure part of turbine can be prevented by automatic control, so that the turbine is easily kept watch on the operation.
