History of steam turbines
History of steam turbines
In history, the mention of turbines was appeared in ancient Greece in history, which has been descriped as a toy. In the 15th century, described the steam turbine Taki al- Din in Ottoman Egypt. In the Renaissance , the concept of turbine appears in the works of Italian scientist Giovanni Branca (1629) and the English John Wilkins in England.
Now known modern steam turbine was invented in 1884 by Sir Charles Parson . The first simple was connected to a dynamo and generate 7.5 kW (10 k) electric power.
Turbine as a source of electricity was used only after the naval wars and revolutions in maritime transport, which greatly expanded its use. Parson's invention was soon improved and scaled Westinghausem American George, who at the same time spread. Parsons soon delivered this turbines from all major power generators and their capacity is increased many times even up to 50,000 kW. During Parson's life, the capacity of generating units has been reduced to about 10,000 times.
To work efficiently using steam were later developed other types of turbines. Engineer Gustav de Lava, for example, accelerated steam before it began to fall on the shoulder blade, which powered a generator turbine. De Laval´s impulse turbine need not be pressure-resistant, but it is a simple and inexpensive solution for most companies. This turbine is therefore capable of handling any pressure, but it has an impact on higher efficiency of the turbine. A number of other variations of turbines has been developed so that could effectively utilize steam generated. Engineer Auguste Rateau put pressure which uses impulse turbine principle de Laval´s procedure. This combination won the 1903 US patent. Thos invention was tested for first time on a French torpedo boat in 1904.
Aurel Stodola was an important theorist dealing with steam and gas turbine. Stodola came from Slovakia and was a physicist and engineer . His most notable work, which was published at the time of his tenure at the school is in Zurich, Switzerland : Die Dampfturbinen und Ihre Aussichten als Wärmekraftmaschinen ( English : Steam Turbine and its future use as a Mechanical Engine) was published in Berlin in 1903. Another book Dampf und Gas -Turbinen (English: Steam and Gas Turbines ) was published in 1922.
Brown-Curtis impulse turbine was developed and patented from Company US International Curtis Marine turbin Company v 1900. This turbine was used like generator for businnes and warships, including warships of Royal Navy.
Currently, turbines are manufactured in various sizes. The smallest ones are below 0.75 kW units ( used as a mechanical drive pumps, compressors and other equipment ) and 1 500 000 kW (these are used to generate electricity).
