Riedler-stumpf turbine Terry turbine. Sturtevant turbine. WebMay 22, 2024 · In 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.

WebMay 22, 2024 · The impulse turbine is composed of moving blades alternating with fixed nozzles. In the impulse turbine, the steam is expanded in fixed nozzles and remains at constant pressure when passing over the blades. Curtis turbine, Rateau turbine, or Brown … WebIn the impulse-type steam turbine, the steam expands in the nozzle and its pressure doesn’t change as it moves over the blades. In the reaction type, the steam expands continuously as it passes over the blades and thus there is a gradual fall in pressure during expansion. Fig. 3: Impulse Turbine vs Reaction Turbine
