Steam turbine - Wikipedia
A steam turbine or steam turbine engine is a machine or heat engine 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 Charles Parsons in 1884.
Reaction Turbine - TurbineGenerator
A reaction turbine is a type of steam turbine that works on the principle that the rotor spins, as the name suggests, from a reaction force rather than an impact or impulse force. This video fully explains the diagram below, or read the step-by-step tutorial on how a reaction turbine works:
Steam Turbine: Working, Types, Components, and Applications
A steam turbine is a mechanical device that transforms the thermal power of steam into mechanical work in form of rotational energy. This turbine is known as a steam turbine because it uses steam as a working fluid. In 1884, the first steam turbine was …

2022年1月13日 · An easy-to-understand introduction to how turbines work, including water, wind, steam, and gas turbines.
Reaction Turbine - an overview | ScienceDirect Topics
Reaction turbines are the turbines that use the pressure as well as the velocity of the moving water to rotate. Reaction turbines are placed in the water stream where the water enters the casing tangentially. After rotating the blades the water axially leaves the casing of the turbine.
How do steam turbines work? - Explain that Stuff
2023年5月7日 · Steam enters from the left through the gray pipe at the top, arriving in the very middle of the turbine and just above it. Then it simultaneously flows in both directions (to the left and the right) through the low-pressure reaction turbine, …
enthalpy drop of steam. A special feature of steam turbines is their ability for very high power, due to the big enthalpy drop realis. ble per steam mass unit. Supply conditions in modern coal-fired electric power stations come to about 250 bar (25 MPa), 565 °C (supercritical). Steam expansion to a 5 kPa vacuum provides about 1500 kJ/kg .
History of steam turbine technology - Encyclopedia Britannica
The first device that can be classified as a reaction steam turbine is the aeolipile proposed by Hero of Alexandria, during the 1st century ce. In this device, steam was supplied through a hollow rotating shaft to a hollow rotating sphere.
Chapter 6. Steam Turbines. Abstract The working principles and the construction forms of steam turbines are discussed, starting from the two historical axial types. These are the impulse type and the reaction type. The chapter is also intended to formulate the general theory of axial turbines.
