WebReaction 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. Francis and propeller turbines are the types of reaction ... WebIn a turbine expansion of steam takes place through the nozzle. In a reaction turbine, the stationary blades act as like a nozzle. 5: The passage area between rotor blades remains constant throughout the blade. The passage area between rotor blades increases from start to end of the blade. 6
WebThe reliability of steam turbines is more, especially where high power is needed. Steam turbines require less mass flow rates compared to gas turbines. High power to weight … WebThe steam turbine. British Electricity ... Fig. 11.26 compares two stationary blade profiles and particle trajectories in both steam passages. For Fig. 11.26, Case A profile, particles are accelerated in the passage, and they attack the pressure side surface at about 70% cord length. This is because of the inertia of accelerated particles and ...
