A steam turbine plant is disclosed having at least one intermediate superheater which is connected to an outlet side of a high-pressure turbine by way of a check valve. A discharge pipe line is connected at one end through a flow-regulating unit to an outlet side of the high-pressure turbine upstream of the check valve and at the other end to a condenser of the plant. The flow-regulating unit is controlled in response to various pressure parameters sensed within the system. The discharge pipe line both improves the idling capability of the plant and reduces the time required to reach operating temperatures from a cold start. |
