Difference between an impulse and a reaction turbine Following are the few points of difference between impulse and a reaction turbine. … [Read more...] about Difference between an impulse and a reaction turbine

Reaction turbine In Reaction turbine major portion of the pressure loss takes place in the rotating wheel. Fluid entering the rotor around its entire circumference is in action. So its rotor need to be so large as compared to the impulse turbine of same power. In reaction turbine, water enters the wheel under pressure and flow over vanes. … [Read more...] about Reaction turbine | Main Components of a reaction turbine

Pelton wheel Pelton wheel is an impulsive turbine used mainly for high head hydro electric schemes. Pelton wheel has the following main components. Nozzle, Runner and buckets, Casing Breaking jet Nozzle Nozzle of a pelton wheel is a circular guide mechanism which guides the water to flow at the desired directions. … [Read more...] about Pelton wheel | Parts of Pelton wheel
