Gallery›Digital Commonwealth — Boston Public Library›Factory tests for the world’s first commercial supercritical pressure steam turbine-generator unit have begun at General Electric Company’s Large Steam Turbine-Generator Department plant in Schenectady, N.Y. Workmen are seen above leveling the seven-ton supercritical pressure element turbine rotor prior to lowering it into the turbine shell. The unit will operate at an initial steam pressure of 4500 psig at a temperature of 1150° F. The highest steam pressure used by turbines now in service in the world is 2400 psig. This powermaker is rated at 125,000 kilowatts and is capable of furnishing enough electricity to satisfy the average yearly electrical needs of over 208,000 persons. This steam turbine-generator unit is scheduled for installation this year at the Philo, Ohio, power station of the Ohio Power Company of the American Gas and Electric System.
