Abstract: PURPOSE:To make available a prompt start-up of an engine even at a freezing ambient temperature, by arranging such that a gas turbine engine is provided with a main and an auxiliary fuel supplying lines, the latter line serving for the supply of light quality oil, and an auxiliary fuel is supplied when the temperature of main fuel is lowered. CONSTITUTION:Upon an engine 1 being started, a main fuel is supplied to the engine 1 from an initial stage of operation if the temperature of main fuel is elevated. In case of the main fuel having a lower temperature at the initial stage of operation, a fuel switching valve 7 is caused to switch into an auxiliary fuel supplying side via a comparator 14, and thereby letting the auxiliary fuel to flow into the engine 1 via a main fuel tube 5B and the fuel switching valve 7. While the auxiliary fuel flows in this manner, a main fuel supplying line causes the main fuel to circulate therethrough via the fuel switching valve 7 and subsequently to be heated up by means of a heater 11. In this manner, the engine can be started up promptly even at a freezing ambient temperature.

Title: Liquid surface possessing type heat exchanger for fast breeder reactor
Inventor: KAWAKAMI TAKASHI
IPC: F28D7/16
Filed: 1984-05-18
Abstract: PURPOSE:To reduce thermal stress generated in a shell of a heat exchanger in proximity to a liquid surface, by a method wherein a heat-accumulating body disposed along a suspended shell is driven in the vicinity of a sodium liquid surface when changing the output. CONSTITUTION:A primary sodium inflow shut-off valve 6 is used also as a heat- accumulating body disposed along the suspended shell 8 and capable of being driven to move to the upper side of the sodium liquid surface. At the time of starting, a steep axial temperature gradient is generated in the sheet 8 in the vicinity of the liquid surface, due to the rise in the sodium temperature and the rise in the sodium liquid surface. To cope with this, the valve 6 immersed in the sodium and heated up to the sodium temperature is raised into a cover gas space to effect heat exchange between the valve 6 and the suspended shell 8, whereby the shell temperature in the gas space in the vicinity of the liquid surface is made to approach the sodium temperature, resulting in a substantially linear temperature distribution. Accordingly, the thermal stress generated in the shell 8 is reduced, and higher reliability of the faste breeder reactor can be contrived.

Under the stationary state of the moving body 9, the magnetic-flux density becomes 0 at the central part, to which the Hall element 20 faces, and the output signal from an amplifier circuit also becomes 0. When the moving body 9 relatively moves leftward (rightward) from this state, the magnetizing curve is relatively moved to rightward (leftward). The residual magnetism by hysterisis in this case is detected with the Hall element 20, and the specified voltage of +(-) is outputted and amplified with the amplifier circuit. Thus, the moving-direction signal is obtained and inputted by a controller.  In this way, the moving direction of the moving body 9 can be detected with the simple structure.
