LARGE TURBINE-GENERATORS: STRAINING AT THE LEASH.

Both production problems and environmental controversy contributed to significant delays in generator plant construction, which precluded the on-line testing of installed generating units before the placing of orders for subsequent units. 3600 rpm single shaft machines have been employed by many companies withing to avoid supercritical pressure cycles. Installed cost curves continue to maintain the six-tenth slope, which calls for a 50% increase in plant cost even with a doubling of plant capacity.
