The modern steam turbine was invented in 1884 by Charles Parsons, whose first model was connected to a dynamo that generated 7.5 kilowatts (10.1 hp) of electricity. [12] The invention of Parsons' steam turbine made cheap and plentiful electricity possible and revolutionized marine transport and naval warfare. [13] Parsons' design was a reaction ...
Used early on in electrical generation and to power ships, turbines were bladed wheels that created rotary motion when high pressure steam was passed through them. The efficiency of large steam turbines was considerably better than the best compound engines, while also being much simpler, more reliable, smaller and lighter all at the same time ...
The uniflow engine used poppet valves and half cylinders which allowed steam to pass into the engine was then used to create a high pressure environment that was key to the function of the uniflow engine. It was used in ships, steam locomotives and steam wagons but was displaced by steam turbines and later marine diesel engines. [50] [52] [53] [17]
The main use for steam turbines is in electricity generation (in the 1990s about 90% of the world's electric production was by use of steam turbines) [5] however the recent widespread application of large gas turbine units and typical combined cycle power plants has resulted in reduction of this percentage to the 80% regime for steam turbines ...
The Ljungström turbine (Ljungströmturbinen) is a steam turbine. It is also known as the STAL turbine, from the company name STAL ( Swedish : Svenska Turbinfabriks Aktiebolaget Ljungström ). The technology has had numerous uses since its conception, from power plants to vehicles as large as the supertanker Seawise Giant .
Steam turbines were fueled by coal or, later, fuel oil or nuclear power. The marine steam turbine developed by Sir Charles Algernon Parsons [3] raised the power-to-weight ratio. He achieved publicity by demonstrating it unofficially in the 100-foot (30 m) Turbinia at the Spithead Naval Review in 1897. This facilitated a generation of high-speed ...
A steam turbine with the case opened Humming of a small pneumatic turbine used in a German 1940s-vintage safety lamp. A turbine (/ ˈ t ɜːr b aɪ n / or / ˈ t ɜːr b ɪ n /) (from the Greek τύρβη, tyrbē, or Latin turbo, meaning vortex) [1] [2] is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work.
The GE steam turbine locomotives were both the first turbine locomotives to be built in North America as well as GE's only steam-powered locomotives. [2] In the words of history professor and author Jeffrey W. Schramm, the locomotives "were the most ambitious and technologically advanced locomotives to have traveled American rails to that point."
