Hence, there is a partial decrease in pressure of the incoming steam. Comparison between Impulse Turbine and Reaction Turbine Last updated: Apr 5, 2016in Hydraulic Machinesby ME Mechanical TeamImpulse and reaction turbine are compared below presented in picture and tabular form.Schematic diagram summarising the differences between impulse turbine and reaction turbine, where the rotor is the rotating part and the stator is the stationary part of the machine. As shown in the figure pressure drop takes place in the nozzles and is distributed in many stages. = Nozzle angle. Vb = Blade velocity. After this it is passed into the nozzle ring and is again partially expanded. Then steam is passed on the moving blades, which further expand the steam and also absorb its velocity. Yahya S.
This indicates that the whirl velocity of fluid at exit of all stages is zero, which is in compliance with the optimum velocity concept (as discussed earlier). It is done by the fixed blades which act as nozzles. if the steam is expanded from the boiler pressure to the condenser pressure in a single stage, then its velocity will be very high. Pressure compounding of Impulse Turbine. The steam coming from the boiler is fed to the first set of fixed blades i.e. 2.Reaction: There is change in both pressure and velocity as the steam flows through the moving blades. The steam produced in the boiler has sufficiently high enthalpy when superheated. they change the direction of the steam and also expand it. "Study of Turbine - Exercise" (pdf).
