A steam turbine consists of a rotor resting on bearings and enclosed in cylindrical casting.
High pressure steam passing through a series of fixed guide blades onto a row of moving blades forces the rotation of the shaft. Thus, a steam turbine could be viewed as a complex series of windmill-like arrangements, all assembled on the same shaft.
Because of their ability to develop tremendous power within comparatively small space turbines have superseded other prime movers for generating electricity.
This turbine, by Metropolitan Vickers, drives a generator via 6000 to 9000 r.p.m. reduction gear.
The compound D.C. generator is capable of producing 250 Kilowatts of power at 650 Volts. It is believed to have been in service at the Southend Water Company pumping station in Tiptree.
Converted to a cut-away working demonstration by Museum volunteers: Project leader Roger Barnes, Volunteers David Twyman, John Swinborne, Michael Clark, Roger Smith, Tony White, David Pring and Tony Earle.
Turbine loaned to the Museum of Power by Essex and Suffolk Water Company.
