Title:
STEAM TURBINE PLANT
Document Type and Number:
Japanese Patent JP2017160804
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a steam turbine plant capable of reducing a thermal elongation difference at a steam turbine without applying any influence against efficiency or control of a heat source device, relying on the presence or non-presence of occurrence of steam by a steam generating device and utilizing effectively heat in the plant.SOLUTION: A steam turbine plant comprises: a heat source device 1 for heating low temperature fluid by heat source medium to obtain high temperature fluid; a steam generating device 2 for generating steam through heat exchanging with the high temperature fluid obtained by the heat source device 1; a steam turbine 3 driven by steam generated at the steam generating device 2; a heating flow passage 13 arranged at the outer surface of a casing 32 of the steam turbine 3; a high temperature fluid supply passage 11 branched from the flow passage for the high temperature fluid in the steam generating device 2, connected to the heating flow passage 13 to supply the high temperature fluid to the heating flow passage 13; and a high temperature fluid flow rate adjustment device 12 for adjusting a flow rate of the high temperature fluid flowing at the high temperature fluid supply passage 11.SELECTED DRAWING: Figure 1
