WebThe 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. WebReaction Turbine. A reaction turbine, therefore, is one that is constructed of rows of fixed and rows of moving blades. The fixed blades act as nozzles. ...

The high-pressure and superheated steam is first passed through the ring of nozzles where high-pressure steam is converted into higher velocity steam and it also gives direction to the flow of steam. Step 2:-. WebAsk an expert. Question: At one stage of a reaction turbine the velocity of the steam leaving the fixed blades is 400 m/s and the exit angle is 22°. The mean blade speed is 200 m/s and the steam consumption is 100 kg/min. Assume the fixed and moving blades to be of identical section.

"WebIn turbomachinery, degree of reaction or reaction ratio (R) is defined as the ratio of the static pressure rise in the rotating blades of a compressor (or drop in turbine blades) to the static pressure rise in the compressor stage (or drop in a turbine stage). Alternatively it is the ratio of static enthalpy change in the rotor to the static enthalpy change in the stage. " - Reaction turbine velocity diagram
