Abstract
A drive turbine having a steam pressure-increasing device connected thereto. Steam taken from a high pressure steam source is utilized as the driving fluid for the pressure-increasing device disposed between the drive turbine inlet and a lower pressure drive turbine steam supply source. The pressure-increasing device increases the pressure level from the steam supply to the drive turbine to maintain a predetermined level of pressure in the supply steam flow.
