  • Patent number: 11415078
    Abstract: In the present invention, a coal gasification combined power generation facility comprises: a feed water supply line (72); a condensate pump (39) and an intermediate-pressure feed water pump (40); a turbine bypass line (32) that bypasses a steam turbine and supplies steam to the condenser (73); and a spray water line (76) that supplies the feed water to the turbine bypass line (32). The coal gasification combined power generation facility has a normal operation mode and a bypass operation mode, and in the bypass operation mode, a control device (80) supplies the feed water to the turbine bypass line (32) and performs a first opening degree control to control the opening degree of the supply adjustment valve so that the amount of feed water supplied to the exhaust heat recovery boiler becomes less than that in the normal operation mode.

  • Publication number: 20120193821
    Abstract: A manufacturing method uses a molding unit to manufacture lenses out of a structure with a plurality of lens intermediates coupled to each other through a runner. The molding unit includes a holding member provided with first opening parts and second opening parts coaxial with each other, and molding chambers. First molding dies and second molding dies are inserted into the first opening parts and the second opening parts respectively. The holding member is further provided with a path that allows introduction of the lens intermediates into the molding chambers. In a manufacturing process, the lens intermediates are guided to predetermined positions in the corresponding molding chambers by operating the structure to cause the lens intermediates and the runner to move along the path. Next, a pressing pressure is applied to the lens intermediates to form molded lenses.
