The general arrangement and principal design features of a 900,000-kw turbine-generator are described and illustrated. Initial steam conditions are 3500-psi 1000 F with reheat to 1000 F. The unit is cross compound with single-flow, high-pressure and double-flow, low-pressure sections with 43-in. last-stage buckets at 1800 rpm and side exhaust to the condensers. The generators, each with a maximum capacity of 527,778 kva, employ water cooling of the armature bars; the 3600-rpm field employs the gap pickup system of conductor cooling and the 1800-rpm field is conventionally cooled with hydrogen.
