A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1. Because the turbine generates rotary motion, it is particularly suited to be used to drive an electrical generator  about 9.

The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Historyedit. A 2. W industrial steam turbine from 1. The first device that may be classified as a reaction steam turbine was little more than a toy, the classic Aeolipile, described in the 1st century by Hero of Alexandria in Roman Egypt. In 1.

Steam turbines were also described by the Italian Giovanni Branca 1. John Wilkins in England 1. The devices described by Taqi al Din and Wilkins are today known as steam jacks. In 1. 67. 2 an impulse steam turbine driven car was designed by Ferdinand Verbiest. A more modern version of this car was produced some time in the late 1. German mechanic. In 1. Soho James Watt designed a reaction turbine that was put to work there. The modern steam turbine was invented in 1. Sir Charles Parsons, whose first model was connected to a dynamo that generated 7. W 1. 0 hp of electricity. The invention of Parsons steam turbine made cheap and plentiful electricity possible and revolutionized marine transport and naval warfare. Parsons design was a reaction type. His patent was licensed and the turbine scaled up shortly after by an American, George Westinghouse. The Parsons turbine also turned out to be easy to scale up. Parsons had the satisfaction of seeing his invention adopted for all major world power stations, and the size of generators had increased from his first 7. W set up to units of 5. W capacity. Within Parsons lifetime, the generating capacity of a unit was scaled up by about 1. First Thank you for reading my instructable. This is a work in progress, I will be adding more and more to this instructable on how to build a steam driven turbine. Steam Download Speed Drops' title='Steam Download Speed Drops' />C. A. Parsons and Company and by their licensees, for land purposes alone, had exceeded thirty million horse power. A number of other variations of turbines have been developed that work effectively with steam. The de Laval turbine invented by Gustaf de Laval accelerated the steam to full speed before running it against a turbine blade. De Lavals impulse turbine is simpler, less expensive and does not need to be pressure proof. It can operate with any pressure of steam, but is considerably less efficient. Serial Number For Dss Player Pro. Auguste Rateau developed a pressure compounded impulse turbine using the de Laval principle as early as 1. US patent in 1. 90. French torpedo boat in 1. He taught at the cole des mines de Saint tienne for a decade until 1. Alstom firm after his death.

His work Die Dampfturbinen und ihre Aussichten als Wrmekraftmaschinen English The Steam Turbine and its prospective use as a Heat Engine was published in Berlin in 1.

The Brown Curtis turbine, an impulse type, which had been originally developed and patented by the U. S. company International Curtis Marine Turbine Company, was developed in the 1. John Brown Company. It was used in John Brown engined merchant ships and warships, including liners and Royal Navy warships. ManufacturingeditThe present day manufacturing industry for steam turbines is dominated by Chinese power equipment makers. Harbin Electric, Shanghai Electric, and Dongfang Electric, the top three power equipment makers in China, collectively hold a majority stake in the worldwide market share for steam turbines in 2. Platts. 1. 4 Other manufacturers with minor market share include Bhel, Siemens, Alstom, GE, Doosan koda Power, Mitsubishi Heavy Industries, and Toshiba. The consulting firm Frost Sullivan projects that manufacturing of steam turbines will become more consolidated by 2. Chinese power manufacturers win increasing business outside of China. Steam turbines are made in a variety of sizes ranging from small lt 0. W lt 1 hp units rare used as mechanical drives for pumps, compressors and other shaft driven equipment, to 1. GW 2,0. 00,0. 00 hp turbines used to generate electricity. There are several classifications for modern steam turbines. Special Herbs Vol 4 Rare. Blade and stage designedit. Schematic diagram outlining the difference between an impulse and a 5. Turbine blades are of two basic types, blades and nozzles. Blades move entirely due to the impact of steam on them and their profiles do not converge. This results in a steam velocity drop and essentially no pressure drop as steam moves through the blades. A turbine composed of blades alternating with fixed nozzles is called an impulse turbine, Curtis turbine, Rateau turbine, or Brown Curtis turbine. Nozzles appear similar to blades, but their profiles converge near the exit. This results in a steam pressure drop and velocity increase as steam moves through the nozzles. Nozzles move due to both the impact of steam on them and the reaction due to the high velocity steam at the exit. A turbine composed of moving nozzles alternating with fixed nozzles is called a reaction turbine or Parsons turbine. Except for low power applications, turbine blades are arranged in multiple stages in series, called compounding, which greatly improves efficiency at low speeds. A reaction stage is a row of fixed nozzles followed by a row of moving nozzles. Multiple reaction stages divide the pressure drop between the steam inlet and exhaust into numerous small drops, resulting in a pressure compounded turbine. Impulse stages may be either pressure compounded, velocity compounded, or pressure velocity compounded. A pressure compounded impulse stage is a row of fixed nozzles followed by a row of moving blades, with multiple stages for compounding. This is also known as a Rateau turbine, after its inventor. A velocity compounded impulse stage invented by Curtis and also called a Curtis wheel is a row of fixed nozzles followed by two or more rows of moving blades alternating with rows of fixed blades. This divides the velocity drop across the stage into several smaller drops. A series of velocity compounded impulse stages is called a pressure velocity compounded turbine. Diagram of an AEG marine steam turbine circa 1. By 1. 90. 5, when steam turbines were coming into use on fast ships such as HMS Dreadnought and in land based power applications, it had been determined that it was desirable to use one or more Curtis wheels at the beginning of a multi stage turbine where the steam pressure is highest, followed by reaction stages. This was more efficient with high pressure steam due to reduced leakage between the turbine rotor and the casing. This is illustrated in the drawing of the German 1. AEG marine steam turbine. The steam from the boilers enters from the right at high pressure through a throttle, controlled manually by an operator in this case a sailor known as the throttleman.
