WebMay 22, 2024 · The reaction turbine was invented by Sir Charles Parsons and is known as the Parsons turbine. In the case of steam turbines, such as would be used for electricity generation, a reaction turbine would require approximately double the number of blade rows as an impulse turbine, for the same degree of thermal energy conversion. Whilst this … WebIn impulse turbines, the steam expands through the nozzle, where most of the pressure potential energy is converted to kinetic energy. The high-velocity steam from fixed nozzles impacts the blades changes its direction, which in turn applies a force.The resulting impulse drives the blades forward, causing the rotor to turn. The main feature of these turbines is …
