Water Steam Cycle

Concept

History n n n 1 st Century - Hero of Alexandria in Roman Egypt 1551 - Taqi al-Din in Ottoman Egypt, who described it as a prime mover for rotating a spit 1648 - by John Wilkins 1660 – by Samuel Pepys 1629 - Italian Giovanni Branca 1884 - The modern steam turbine was invented in 1884 by the Englishman Sir Charles Parsons, whose first model was connected to a dynamo that generated 7. 5 k. W of electricity

Steam Turbine

Steam Turbine Types 1 - Straight Condensing turbines which allow steam to expand to the lowest possible pressure before it is condensed into water. 2 - Back-pressure and topping turbines in which steam is exhausted before it is fully expanded. Generally, provide low pressure steam for heating or process. 3 - Extraction turbine in which steam is extracted (controlled or uncontrolled) during the expansion process for use in othe application such as district heating.
