If high velocity of steam is allowed to flow through one row of moving blades, it produces a rotor speed of about 30000 rpm which is too high for practical use. It is therefore essential to incorporate some improvements for practical use and also to achieve high performance. This is possible Three main types of compounded impulse turbines are: blades, rotors, in a series, keyed to a common shaft; so that either the steam pressure or the jet velocity is absorbed by the turbine in stages. yp p p a. Pressure compounded b. Velocity compounded c Pressure and velocity compounded impulse turbines c. Pressure turbines and when multi-staging, velocity compounding over pressure compounding. The degree of reaction of a turbine stage (stator nozzles plus rotor blades) is the fraction of the fluid static enthalpy drop which occurs in the rotor (see section 2. of this Lecture). In an impulse turbine, the degree of reaction is zero, meaning The velocity compounded Impulse turbine was first proposed by C G Curtis to solve the problem of single stage Impulse turbine for use of high pressure and temperature steam. The rings of moving blades are separated by rings of fixed blades. The moving blades are keyed to the turbine shaft and the fixed blades are fixed Apr 13, 2017 Pressure and Velocity Compounded Impulse Turbine| Steam Turbine| steam turbine principle operations| steam turbine pdf| power | steam engine| velocity | maximum. Compounding of steam turbines: The method in which energy from steam is extracted in more than single stage is called Compounding. A multi-stage turbine i.e having more than one set of rotors and nozzles is called compounded turbine. 1.

STEAM TURBINE The velocity-compounded impulse turbine was first proposed by C.G. Curtis to solve the problems of a single-stage impulse turbine for use with high pressure and temperature steam. Compounding of impulse turbine. Compounding is done to reduce the rotational speed of the impulse turbine to practical limits. Compounding is achieved by using more than one set of nozzles, blades, rotors, in a series, keyed to a common shaft; so that either the steam pressure or the jet velocity is absorbed by the turbine Compounding is achieved by using more than one se$
