The word "turbine" was coined in 1822 by the French mining engineer Claude Burdin from the Latin turbo, or vortex, in a memo, "Des turbines hydrauliques ou machines rotatoires grande vitesse", which he submitted to the Acadmie royale des sciences in Paris.[3] Benoit Fourneyron, a former student of Claude Burdin, built the first practical water turbine. Bladeless turbine uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. The primary numerical classification of a turbine is its specific speed. What is an extraction turbine? Answer: In an extraction turbine, steam is withdrawn from one or more stages, at one or more pressures, for heating, plant process, or feedwater heater needs. Sackett, p. Play media Operation of a flyball governor to control speeds of a water turbine . Boyden developed an outward flow turbine that improved on the performance of the Fourneyron turbine. The only known surviving example of this type of engine used in power production, dating from 1851, is found at Hacienda Buena Vista in Ponce, Puerto Rico.[3][4]. As the water swirls inward, it accelerates, and transfers energy to the runner.

Most jet engines rely on turbines to supply mechanical work from their working fluid and fuel as do all nuclear ships and power plants. The migration from water wheels to modern turbines took about one hundred years. See: Prony and Girard (1824) "Rapport sur le mmoire de M. Retrieved 29 January 2015. Water flows past the angled blades, pushing them around and turning the shaft to which they're attached. Wind turbines are perhaps the most familiar examples of reaction turbines. The spinning water turbine drives a generator that turns the mechanical energy into electrical energy. In a reaction turbine, each row of blades is called a "stage." A single Curtis stage may consist of two or more rows of moving blade. In this way, energy is transferred from the water flow to the turbine. Impulse and reaction turbines Turbines work in two different ways described as impulse and reactionterms that are often very confusingly described (and sometimes completely muddled up) when people try to explain them. Turbines are often part of a larger machine. Old turbine runners may have a significant amount of stainless steel added this way by the end of their lifetime. In practice, modern turbine designs use both reaction and impulse concepts to varying degrees whenever possible. Small turbines (mostly under 10 MW) may have horizontal shafts, and even fairly large bulb-type turbines up to 100 MW or so may be horizontal. All rights reserved. Shrouded turbine. c5cfac679b
