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 WebApr 27, 2024 · Impulse turbines change the direction of fluid flow or gas jet at high velocities. The resulting impulse rotates the turbine, the kinetic energy of fluid flow reduces, and then it leaves the turbine. In the turbine moving blades, there is no pressure change of the fluid (liquid or gas).
