  • Patent number: 10378550
    Abstract: An apparatus for preventing an axial-flow compressor from stalling by employing a casing treatment includes an outer casing having an inner wall with a slot formed to face a rotor blade, an inner casing moveable so as to open the slot in an unstable operating region and close the slot of the outer casing in a stable operating region, and a drive means for moving the inner casing along the axial direction of the outer casing. Thus, the apparatus can be applied not only to a casing treatment structure where the slope of a slot does not vary with the rotational position of the rotor, but also to a casing with a variously shaped slot such as a radial slot or an axial skewed slot.

  • Patent number: 10378396
    Abstract: A variable valve-operating device for an internal combustion engine has a cam carrier with cam lobes formed therearound to act on an engine valve and with a speed increasing side lead groove and a speed decreasing side lead groove formed therearound to be engaged with a speed increasing side switching pin and a speed decreasing side switching pin, respectively, to axially shift the cam carrier, to selectively make one of the cam lobes to be operative. A speed increasing side entry lead groove portion of the speed increasing side lead groove is formed in a position axially overlapping a low speed steady position lead groove portion of the speed decreasing side lead groove. A speed decreasing side entry lead groove portion of the speed decreasing side entry lead groove is formed in a position axially overlapping a high speed steady position lead groove portion of the speed increasing side lead groove. The variable valve-operating device can thus be miniaturized by reducing the axial width of the cam carrier.

  • Patent number: 10358947
    Abstract: This combined cycle gas turbine plant has a gas turbine (104) and a steam turbine (106) mounted on the same shaft. A control system is configured for switching the plant from a rated mode of operation, in which the plant is operated on gas turbine output and steam turbine output, to a reduced load mode of operation, in which the plant is operated on gas turbine output alone. The switch from the rated mode of operation to the reduced load mode of operation occurs if plant demand decreases below a predetermined threshold. The steam turbine is run under full speed no load conditions in the reduced load mode of operation, and is heated using controlled steam admission, to maintain the steam turbine in a heated ‘stand-by’ state.
