Steam turbine minimum load - Machines & Machining ...

Jul 12 2013 · It may make more sense to operate the steam turbine cycle at higher loads just to better serve process needs. Similarly while process steam may be reduced from the extraction points more optimal use of extraction flows for feedwater heating may improve cycle efficiency enough to mitigate some of the burdens of reduced process needs.

Turbine - Steam turbines | Britannica

Turbine - Turbine - Steam turbines: A steam turbine consists of a rotor resting on bearings and enclosed in a cylindrical casing. The rotor is turned by steam impinging against attached vanes or blades on which it exerts a force in the tangential direction. Thus a steam turbine could be viewed as a complex series of windmill-like arrangements all assembled on the same shaft.
