Steam turbine having exhaust enthalpic condition control and related method

摘要

A steam turbine (100) includes a casing (120) including a steam inlet (122) and an exhaust (124), the casing (120) enclosing operative structure of the steam turbine (100); a valve (102) controlling introduction of a steam flow (104) at a 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.
