  • Patent number: 10215058
    Abstract: Discloses is a turbine power generation system having an emergency operation means and an emergency operation method therefor that are capable of controlling excess heat accumulated during emergency operation, and recycling the accumulated heat. A turbine power generation system includes: an inlet sensor part including a thermometer, a pressure gauge, and a flowmeter that are installed between the heater and the inlet valve and; an emergency discharge part including a branch pipe connected to the steam, and a heat control means installed on the branch pipe. Accordingly, the system and the method are capable of reducing a heat overload during an emergency operation by transferring a heat amount exchanged in the heat storage device to the heat consuming facility, minimizing thermal consumption by recycling the same, and preventing various problems caused by stopping an operation of the turbine power generation system.

  • Publication number: 20180142555
    Abstract: Embodiments of the present invention relate to a steam turbine in which unnecessary axial force is reduced. The steam turbine is capable of preventing a working fluid discharged from each nozzle-equipped rotary body from acting as resistance to the nozzle-equipped rotary bodies. The steam turbine includes a housing, a turbine shaft supported pivotably in the housing, a nozzle-equipped rotary body, and a guide panel. The nozzle-equipped rotary body is in the shape of a plurality of disks stacked along the axial direction of the turbine shaft, is integrally coupled to the turbine shaft, and has at least one or more nozzle holes formed therein so as to rotate as the working fluid is ejected. The guide panel is positioned at the rear end in a flow direction of the working fluid of the nozzle-equipped rotary body and fixed to the housing to guide the flow of the working fluid.

  • Publication number: 20160268098
    Abstract: A scanning electron microscope capable of controlling the spot of an electron beam and a measurement method using the same. The scanning electron microscope includes electron magnets disposed in a path in which an electron beam irradiated to a sample moves from the electron beam source of the scanning electron microscope to a sample and configured to control and irradiate the spot of the electron beam in a linear electron beam having a different horizontal to vertical ratio. A control unit controls a ratio and direction of the spot of the electron beam by controlling a supply voltage of the electron magnets.
