STEAM TURBINE HAVING EXHAUST ENTHALPIC CONDITION CONTROL AND RELATED METHOD

摘要

<P>PROBLEM TO BE SOLVED: To provide a steam turbine having exhaust enthalpic condition control and a related method. Ž<P>SOLUTION: The steam turbine 100 includes a casing 120 including a steam inlet 122 and an exhaust 124, the casing 120 enclosing an operative structure of the steam turbine 100; a valve 102 controlling introduction of a steam flow 104 at the predetermined location 150 of the steam turbine 100 to impact an enthalpic condition of steam exiting the exhaust 124; and a controller 106 controlling operation of the valve 102 to attain a desired enthalpic condition of steam exiting the exhaust 124. Controlling operation of the valve 102 allows for attainment of a desired enthalpic condition of the steam exiting the exhaust 124 for use in another industrial process without having to modify the steam turbine 100 structure.
