APPARATUS FOR CONTROLLING LEAKAGE STEAM OF STEAM TURBINE

摘要

An apparatus for controlling leakage steam of a steam turbine is provided to prevent condensed water from being formed in the low pressure line by supplying steam of high pressure into a low pressure line in case leakage of steam occurs in the low pressure line. An apparatus for controlling leakage steam of a steam turbine comprises a high pressure line(12) and a low pressure line(14) connected between a steam turbine and a vacuum chamber; a pressure compensating line(18) connected to the vacuum chamber; a pressure detecting unit(100) generating leakage steam detection signal, connected to the low pressure line; a control part(110) analyzing leakage steam detection signal of the leakage steam detection part; and a steam supply part connecting the high pressure line and the pressure compensating line. The steam supply part includes a steam ejector(130).
