Abstract (en)

[origin: WO2022045446A1] The present invention provides a steam turbine comprising: a steam injection port; a steam distribution container, connected to the steam injection port, that provides a single chamber formed in an elongated shape along the front of the steam turbine; and a plurality of spray nozzles that communicate with the steam distribution container and individually branch out and extend to the inside of the lower portion of a housing to spray an impeller housed therein with steam. Injection valves for supplying or cutting off the supply of steam to respective spray nozzles are installed at the entrance of the turbine. A steam exit having a gradually decreasing diameter and a steam collection container, connected to the end of the steam exit, that provides a single chamber formed in an elongated shape along the steam turbine are installed in the upper portion of the housing.
