Compilation Description
N60-8.83 type steam turbine is a 60 MW turbine model that is designed and manufactured based on the advanced technologies that are introduced domestically and internationally. It is a new kind of condensing turbine of impulse type, high temperature, pressure and single cylinder. It matches boiler of corresponding capacity and steam turbine generator to form thermal generation unit. It is of basic load in electricity grid, and can also regulate the peak.
17Weight of the steam turbine: ~141t, (including valves, steam pipes, frame and levelling parallels)
18Maximum lifting weight: ~25 tons(for lifting upper cylinder assembly during maintenance)
~38 tons(for lifting lower cylinder assembly during installation)
19Maximum lifting height : 6.36m (with respect to the operation floor) 20.Elevation of the operation floor: 8 m
