2. Water wheel - Wikipedia

   en.wikipedia.org/wiki/Water_wheel

   A water wheel is a machine for converting the kinetic energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a large wheel (usually constructed from wood or metal), with numerous blades or buckets attached to the outer rim forming the drive mechanism. Water wheels were still in commercial ...

3. Water turbine - Wikipedia

   en.wikipedia.org/wiki/Water_turbine

   The main difference between early water turbines and water wheels is a swirl component of the water which passes energy to a spinning rotor. This additional component of motion allowed the turbine to be smaller than a water wheel of the same power. They could process more water by spinning faster and could harness much greater heads.

4. Auxiliary feedwater - Wikipedia

   en.wikipedia.org/wiki/Auxiliary_feedwater

   The typical steam turbine used in the aux feedwater systems are the “solid wheel” or “water wheel” Terry Steam Turbines manufactured by the Curtiss-Wright Corporation in Summerville, SC. In contrast to emergency core cooling systems for loss-of-coolant accidents, the auxiliary feedwater system does not inject directly into the reactor ...

5. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator, also called an electric generator, electrical generator, and electromagnetic generator is an electromechanical device that converts mechanical energy to electrical energy for use in an external circuit.

6. Turgo turbine - Wikipedia

   en.wikipedia.org/wiki/Turgo_turbine

   The water's potential energy is converted to kinetic energy with a nozzle. The high speed water jet is then directed on the turbine blades which deflect and reverse the flow. The resulting impulse spins the turbine runner, imparting energy to the turbine shaft. Water exits with very little energy. Turgo runners are extremely efficient

7. Turbo generator - Wikipedia

   en.wikipedia.org/wiki/Turbo_generator

   A turbo generator is an electric generator connected to the shaft of a turbine (water, steam, or gas) for the generation of electric power. [ note 1 ] Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric ships.

8. Pelton wheel - Wikipedia

   en.wikipedia.org/wiki/Pelton_wheel

   Old Pelton wheel from Walchensee Hydroelectric Power Station, Germany. The Pelton wheel or Pelton Turbine is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [1] [2] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot ...

9. Screw turbine - Wikipedia

   en.wikipedia.org/wiki/Screw_turbine

   The Archimedes screw generator consists of a rotor in the shape of an Archimedean screw which rotates in a semicircular trough. Water flows into the screw and its weight presses down onto the blades of the turbine, which in turn forces the turbine to turn. Water flows freely off the end of the screw into the river.
