Compounding of steam turbines is the method in which energy from the steam is extracted in a number of stages rather than a single stage in a turbine. In all turbines the rotating blade velocity is proportional to the steam velocity passing over the blade. If the steam is expanded only in a single stage from the boiler pressure to the exhaust pressure, its velocity must be extremely high.
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.
Steam Turbines. Steam turbines are a mature technology and have been used since the 1880s for electricity production. Most of the . electricity generated in the United States is produced by steam turbines integrated in central station power plants. In addition to central station power, steam turbines …
Steam Boilers, Engines, Nozzles and Turbines. A fusible plug is fitted in small boilers in order to _____? 0. A. avoid excessive build up of pressure B. avoid explosion Steam in water tube boiler as compared to fire tube boiler_____? 0. A. can be raised rapidly
First steam turbine and History of steam turbines. Historically, the first steam turbine of which we have proof was built by Heron of Alexandria around 175 BC, which consisted of a metal sphere with two nozzles at their poles and oriented in the same direction where the steam escaped. The sphere rotated diametrically, resting on the boiler
Elliott steam turbines are rated for inlet steam conditions up to 2000 psig/1005 degrees F and speeds up to 20,000 rpm. Elliott steam turbines come in a variety of sizes ranging from small, 20 HP (15 kW) single-stage units, to large 175,000 HP (130,000 kW) multi-valve, multi-stage extraction condensing units.

Steam turbines are made in a variety of sizes ranging from small <0.75 kW (<1 hp) units (rare) used as mechanical drives for pumps, compressors and other shaft driven equipment, to 1,500 MW (2,000,000 hp) turbines used to generate electricity. There are several classifications for modern steam turbines. Blade and stage design
