Abstract
An apparatus for reducing windage loss of steam turbines according to an embodiment of the present disclosure is to reduce or minimize damage to a blade caused by a rise in temperature at an outlet stage of a high-pressure turbine.
Claims17
An apparatus, comprising:
- a turbine unit including a high-pressure turbine, a medium-pressure turbine, and a low-pressure turbine;
- a condenser that receives steam from the low-pressure turbine;
- a tank in which steam generated at the time of operation of the turbine unit converts into condensed water and is stored;
- a steam supplier that supplys additional steam to an inlet stage of the high-pressure turbine;
- a sensor that senses the temperature at the outlet stage of the high-pressure turbine and internal pressure;
- and
- a controller configured to control an amount of steam supplied by the steam supplier based on temperature or pressure data sensed by the sensor.
