Turbine

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. Because of its Get price

Rotating Equipment: Modern Steam Turbines

2009/10/22The modern steam turbine was invented by Sir Charles Parson in 1888. There are two types of steam turbines- impulse and reaction- however some apply a combination of both designs. A steam turbine has three stages: High, Intermediate, and Low Pressure. Superheated steam enters the HP stage, expands and returns to the boiler before entering the IP stage as reheated steam, Get price
