<p>The present invention relates to a method and means for enhancing the efficiency of water turbines, in particular Pelton turbines. The water turbine comprises a rotatable turbine wheel having a wheel disc and preferably a plurality of buckets fixed to the wheel disc, and further comprising at least one nozzle for expelling a water jet on the at least one bucket. The rotatable wheel and the at least one nozzle are arranged in a casing with a water outlet, and the interior of the casing is provided with means for reducing splash back of discharging water and detrimental water spray on the rotatable wheel. One or more energy damping devices is/are attached on stationary, water splash exposed parts inside the turbine casing in order to dissipate energy at least from water of high velocity leaving the buckets and/or dense pulverised water mist.</p> |
