A steam turbine-generator system includes a reheater bypass valve which cooperates with both a high- and low-pressure bypass valve in the early stages of turbine loading to divert steam in a bypass flow from a high-pressure turbine to the input of a reheat turbine without passing the steam through a reheat portion of the boiler. The pressure and temperature drops in the high-pressure turbine are controlled by the setting of the pressure threshold of the low-pressure bypass valve. A check valve prevents steam flow into the reheat portion of the boiler unt...
A steam turbine-generator system comprising: a high-pressure steam turbine; a reheat turbine; a boiler including means for heating steam for delivery to said high-pressure steam turbine and a boiler reheat portion for reheating an exhaust steam from said high-pressure steam turbine for delivery to said reheat turbine; main valve means for admitting steam from said boiler to said high-pressure steam turbine; an intercept control valve for admitting steam from said boiler reheat portion to said reheat turbine; means for maintaining at least a selectable pr...
