Warming arrangement for a power plant

A warming arrangement, for a power plant, comprising:

• a first steam turbine, for expanding steam;
• and
• a first warming system, for warming the first steam turbine using a first warming gas, the first warming system includes:
• a first makeup line, fluidly connected to the first steam turbine, for directing the first warming gas into the first steam turbine;
• a first recycle line, fluidly connected to the first steam turbine, for conveying the first warming gas from the first steam turbine,
• a first gas moving device, in either the first makeup line or the recycle line, for moving the first warming gas through the first warming system;
• and
• a first heater, in either the first makeup line or recycle line so as to heat the first warming gas before it enters the steam turbine;
• wherein the first warming system further comprises:
• a first pressure measurement device configured and arranged to determine a gauge pressure in the steam turbine;
• and
• a controller, configured to control a flow rate of the first warming gas through the first steam turbine, based on the first pressure measurement device.
