About Steam Turbine

A steam turbine is a mech. device that extractsthermal energy from pressurized steam, andconverts it into rotary motion.

It has almost completely replaced thereciprocating piston steam engine (invented by

Thomas Newcomen and greatly improved byJames Watt) primarily because of its greaterthermal efficiency and higher power-to-weightratio.

Because the turbine generates rotary motion, it is

particularly suited to be used to drive anelectrical generator about 80% of all electricitygeneration in the world is by use of steamturbines.
