Steam Turbines and Boilers

The steam turbine is a device for obtaining mechanical work from the energy stored in steam. Steam enters the turbine with a high energy content and leaves after giving up most of it. The highpressure steam from the boiler is expanded in nozzles to create a highvelocity jet of steam. The nozzle acts to convert heat energy in the steam into kinetic energy. This jet is directed into blades ...
