This paper discusses the design features and general arrangement of a 321-mw close-coupled cross-compound 3600/1800-rpm steam turbine-generator unit. The machine is designed for operation with subcritical pressures and with steam temperatures that permit using ferritic materials. It was the first machine to be ordered in the 300-mw size range and is installed in the River Rouge Station of The Detroit Edison Company.

Consolidated Edison’s 1000-mw steam turbine-generator unit for Ravenswood No. 3 will operate on a 2400-psig, 1000/1000 F steam cycle. Arrangement is close-coupled 3600/1800-rpm, cross compound, with all five turbines double flow. Both generators are of fully supercharged, hydrogen-cooled design. At each end of the 3600-rpm shaft are direct-driven half-size boiler-feed pumps while the big units two gear-driven exciters are in tandem at the generator end of the 1800-rpm shaft. The three double-flow, low-pressure turbines use 40-in. exhaust spindle blades. This world-record unit incorporates design features to assure fast starting and loading, high reliability, and efficient performance.

The flaws such as crack or slag inclusion, in the welded seam of header of a 300MW steam turbine generator unit, were detected by the ultrasonic non-destructive inspection. Based on the crack modeling, the finite element method (FEM) was used to calculate and analyze the displacement field, stress field and stress intensity factors of the cracks under the conditions of warm start, cold start and normal operation, and the residual service life was predicted. Analyzing results showed that these flaws would not bring about primary brittle fracture and propagation of crack was harmless to safe in operation.

Principal Design

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.
