WebThe following disadvantages of Impulse Turbine is: The installation cost is more. The bucket efficiency is low. The impulse turbine takes more space for installing as compared to the reaction turbine. Impulse turbine works only in high heads which is difficult to control. It has a low working speed. The water is admitted only in the form of jets. WebImpulse turbines are defined as turbines in which high-velocity jets of water or steam collide with the blades of the turbine to rotate the turbine and produce electricity using this winding. The impulse turbine is so named because it acts on the impulse force created for the striking blade of the water jet. Impulse Turbine and Reaction Turbine

Want to see the full answer? Check out a sample Q&A here. See Solution. Webair passes over the turbine blade and the typical design of the turbine blade gives unidirectional rota-tion to the generator shaft. Hence, the turbines are called as ‘‘self-rectifying impulse turbine’’ or ‘‘bidirec-tional turbine’’. A bidirectional turbine needs guidevanes (GVs) placed up and down stream of the turbine blades or demographic entry
