WebMay 22, 2024 · Impulse Turbine – velocity compounding. A velocity-compounded impulse stage consist of a row of fixed nozzles followed by two or more rows of moving blades and fixed blades (without expansion). This divides the velocity drop across the stage into several smaller drops. In this type, the total pressure drop (expansion) of the steam take place … 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.
