。 The main steam generated in the boiler is guided through a steam control valve to a high pressure steam turbine, and the steam from this high pressure steam turbine is reheated in a reheat boiler to become reheat steam.
This reheated steam is guided to a medium-pressure/low-pressure turbine through a reheated steam stop valve and an intercept valve, as well as to an extraction line. The steam control valve is controlled by a signal from a governor installed on the turbine shaft. , wherein the intercept valve is controlled by a signal from the governor and a signal based on the pressure signal of the bleed line; A control device for a reheat steam turbine, characterized in that a quick closing device is connected to quickly close the reheat steam stop valve prior to the closing operation of the intercept valve.
