Compounding of steam turbine pdf
April 13, 2017 April 13, 2017 Steam Turbines This type of turbine is a mixture of pressure and velocity compounding. There are two wheels or rotors and on each, only two rows of moving blades are attached since two-row wheel are efficient than three-row wheel.
Large compound turbines are an application of compounding, as are the multiple rows of blades used in many gas turbines, but neither is normally referred to as a compound engine. The several sets of blades in a single turbine are perhaps better thought of as similar in principle to the uniflow steam engine than to compounding.

Compounding Of Steam Turbines Steam jet does maximum work with good economy when the blade speed is just half the steam speed. Due to very large rate of expansion, the steam leaves the nozzle at a very high velocity (Supersonic, since the pressure ratio exceeds the critical pressure ratio and the nozzle thus used is Converging – Diverging) of about 1000 m/sec. Even though the rotor diameters
The compound steam turbine of 10 horse power (page 7) ran at 18,000 revolutions per minute, and had slightly elastic bearings to allow it to rotate about its dynamic or principal axis. The turbine teeth or blades were like a cog wheel, set at an angle and sharpened at the front edges, and the
COMPOUNDING IN STEAM TURBINES High pressure and high temperature steam is used in the power plant to increase their. thermal efficiency. If the steam is expanded or the entire pressure drop from the boiler pressure to the condenser pressure is carried out in one single stage only, then the velocity of steam entering into the turbine will be
