"WebMay 22, 2024 · The reaction turbine is composed of moving blades ( nozzles) alternating with fixed nozzles. In the reaction turbine, the steam is expanded in fixed nozzles and also in the moving nozzles. In other words, the steam is continually expanding as it flows over the blades. There is pressure and velocity loss in the moving blades. " - Reaction stage turbine

Reaction stage turbine

WebDepending on the degree of reaction, we distinguish the following types of turbine stages: • Impulse stage— R = 0–0.25 In an impulse turbine stage, the drop in pressure of the fluid takes place almost only in the nozzles and not in the moving blades. This is obtained by making the rotor blade passage a constant cross-sectional area. • Web2 days ago · Reaction turbines In a reaction turbine, forces driving the rotor are achieved by the reaction of an accelerating water flow in the runner while the pressure drops. The reaction principle can be observed in a …

However, there are several different ways to classify the turbine as follow: By the action of steam: Impulse or Reaction. By the direction of steam flow: Axial, Radial, Mixed, Tangential, Helical, or Reentry.

WebThe first-stage blades in most gas turbines are impulse-type blades (zero reaction), while the second- and third-stage blades are reaction-type blades usually (50% reaction). The impulse stages produce about twice the output of a comparable 50% reaction stage, while the efficiency of an impulse stage is less than that of a 50% reaction stage. WebAug 4, 2024 · The work produced by an impulse turbine with a single-stage operating at the same rotational speed is twice that of a reaction turbine. Therefore, the cost of a reaction turbine is much higher for the same amount of work because it needs more stages. Additionally, the efficiency of a reaction turbine is higher due to blade suction effects.
