Working Mechanism for Steam Turbine When steam at high pressure is admitted to one side of a turbine it will force the blade assembly to rotate This rotation is achieved most effectively if the exhaust side of the turbine is maintained at low pressure The low pressure condition is assured by the presence of a condenser, typically a chamber into which the exhaust steam is admitted and kept cool by a flow of water from a river, lake, or other source a rotor of a modern steam turbine The mechanical energy of the rotating used in a power plant turbine can be coupled to other machinery, often to an electric generatorA rotor of a modern steam turbine, used in a power plant • When steam at high pressure is admitted to one side of a turbine, it will force the blade assembly to rotate. • This rotation is achieved most effectively if the exhaust side of the turbine is maintained at low pressure. • The low pressure condition is assured by the presence of a condenser, typically a chamber into which the exhaust steam is admitted and kept cool by a flow of water from a river, lake, or other source. • The mechanical energy of the rotating turbine can be coupled to other machinery, often to an electric generator.
