Reaction Turbine

Reaction Turbine Points : Reaction Turbine, Definition Definition In a reaction turbine, the steam enters the wheel under pressure and flows over the blades. The steam, while gliding, propels the blade and makes them to move.
As a matter of fact, the turbine runner is rotated by the reactive forces of steam jets. The backward motion of the blades is similar to the recoil of a gun. It may be noted that an absolute reaction turbine is rarely used in actual practice.
