Abstract :
In the brief period often years the 3,600-rpm turbine generator has so grown in ratings that it has driven, in effect, the slower speed 4-pole generating unit from tlie central-station field except for the largest capacity installations. But here, too, the death knell is being sounded by the construction of a 100,000-kw 3,600-rpm unit that will operate with steam at 1,500 pounds per square inch gauge pressure and 1,050 degrees Fahrenheit, the highest inlet temperature yet attempted.
