What is an impulse turbine?

Impulse turbine is a type of turbine that often occurs in steam power plants. The impulse turbine was invented at the end of the 19th century by the Swedish inventor Gustaf de Laval and has since improved significantly and has been employed in different ways. However, turbines are not exclusive to steam; The pulse turbine is any turbine whose rotation is created by fixed nozzles, where the nozzles of the working fluid - be it steam, water or other gases - push buckets on the rotor. This is very different from the reaction turbine, whose nozzles rotate with the rotor itself. A good example of the reaction turbine would be an automatic garden sprayer and the pulse turbine is more like a toy toy. Kinetic energy from the steam speed is then used to rotate the steam turbine shaft at very high speeds. Fixed nozzles in Front of the Spinning Blalades help increase steam speed at the expense of pressure drop. This is a very important part of the process because speed and pressure play equally important roles in the turbine efficiency. That's himThe bottom, unlike the reciprocal steam engine, where the revolution of the engine per minute is mainly dependent on steam pressure.

Another type of pulse turbine is the pulse water turbine, which is used in hydroelectric power plants around the world. These types of turbines are known as Pelton Wheels and the rotor consists of many buckets to raise running water. However, the Pelton wheels differ very much from the typical water wheel; The water wheels rely on the weight of the water for rotation, but the pelton wheels rely on the flow. Pelton wheels are incredibly efficient because they use almost all energy from the speed of water.

pulse turbines come in a wide range of types and sizes. Sizes range anywhere from small facilities with less than one horse force to large industrial turbines capable of providing more than 2 million horsepower. Smaller turbines are rare that have been used only for smaller tasks suchBA electricity in steam locomotives. However, larger turbines are responsible for about 80 percent of world electricity. These turbines are often a combination of impulse and reaction turbines.
