Witryna• Sometimes, 50% reaction turbines are also called Parsons turbines. • The velocity diagrams for the moving blades of a 50% reaction turbine are shown in Fig. 7.31. • With a simple impulse type the value of Vr2 (= kb Vr1 ) would be given by BE, but in the reaction turbine this velocity is increased to BC by further expansion of the steam ... Witryna25 lis 2014 · Reaction Turbine A reaction turbine is constructed of rows of fixed and rows of moving blades. The fixed blades act as nozzles. The moving blades move as a result of the impulse of steam received (caused by change in momentum) and also as a result of expansion and acceleration of the steam relative to them.
