In case of impulse steam turbine
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 to the casing. The high pressure steam coming from the boiler is expanded in the nozzle first. The Nozzle converts the pressure energy of the st… WebOct 1, 2014 · Chapter-4 (Steam Turbines): CLASSIFICATION OF STEAM TURBINES: Impulse turbines, Reaction turbines, The impulse principle, The reaction principle, The impulse turbine,...

WebImpulse steam turbines Designed for top thermodynamic and mechanical performance Talk To An Expert Highlights Overview Highlights Benefits High reliability High efficiency Large-scale testing capability available Features Single-flow turbines with impulse blades for high reliability and efficiency over a broad range of operating conditions WebThe following disadvantages of Impulse Turbine is: The installation cost is more. The bucket efficiency is low. The impulse turbine takes more space for installing as compared to the reaction turbine. Impulse turbine works only in high heads which is difficult to control. It has a low working speed. The water is admitted only in the form of jets.
WebIn the impulse-type steam turbine, the steam expands in the nozzle and its pressure doesn’t change as it moves over the blades. In the reaction type, the steam expands continuously as it passes over the blades and thus there is a gradual fall in pressure during expansion. Fig. 3: Impulse Turbine vs Reaction Turbine WebThe Impulse Steam Turbine. The Rateau steam turbine is a typical modern multistage impulse turbine. Fig. 4 shows a longitudinal section through a machine of this type constructed in 1919 by the Metropolitan Vickers Electrical Co. for the Dalmarnock power station, the machine in question having a maximum continuous rating of 18,750 K.W. at a …
