- 3. Steam Turbine The steam turbine is a rotary mehanical device that converts the thermal energy of the steam (high pressure and temperature) into useful mechanical energy on a rotating output shaft. thermal energy mechanical energy This shaft is connected to a generator through which power is produced. The steam turbine is steam driven rotary engine. ANASEEM AL-HANINI
- 4. Principle of steam turbine The steam energy is converted mechanical work by expansion through the turbine. Expansion takes place through: 1. a series of fixed blades(nozzles) 2. moving blades. In each row fixed blade and moving blade are called stage ANASEEM AL-HANINI
- 8. the motive power in a steam turbine is obtained by the rate of change in moment of momentum of a high velocity jet of steam impinging on a curved blade which is free to rotate. ANASEEM AL-HANINI
- 10. Classifications of Steam Turbines: In impulse turbines, the rotor blades, shaped like buckets, convert kinetic energy into shaft rotation. No pressure drop occurs across the rotor Impulse (Delaval turbine) Impulse Reaction turbine (Parsons turbine) In the impulse-reaction turbine, the rotor blades charnel themselves are assuaged to be nozzles and so a pressure drop occurs across the moving blade.

- 30. The prototype of the steam turbine made by de Greek mathematician Heron of Alexandria in 120 B.C., which was a sphere with bent pipes attached to its circumference which caused the sphere to spin in reaction to the steam expelled from them. Historical Review video ANASEEM AL-HANINI
- 31. In 1878, a Swedish engineer, Carl G. P. de Laval developed a simple impulse turbine, using a convergent-divergent (supersonic) nozzle which ran the turbine to a maximum speed of 100,000 rpm. In 1897 he constructed a velocity-compounded impulse turbine (a two-row axial nobine with a row of guide vane stators between them. Auguste Bateau in France started experiments with a de Laval turbine in 1894, and developed the pressure compounded impulse turbine in the year 1900. In the USA , Charles G. Curtis patented the velocity compounded de Lavel turbine in 1896 and transferred his rights to General Electric in 1901. In England , Charles A. Parsons developed a multi-stage axial flow reaction turbine in 1884. ANASEEM AL-HANINI
- 34. of these religion-oriented devices was the “automatic door opener” that was designed for use as part of a spiritual service. Using a hidden heat source that created steam pressure, and implemented with a secretive system of ropes and pulleys, the doors that separated the faithful from the temple’s holy altar would initially be closed; then, when pressure was sufficient, the doors would mysteriously open as if under their own power – or, more to the point, initiated by a divine force.
