A gear cooling structure includes: a gear including a plurality of teeth extending in a particular direction; and a nozzle that jets out oil toward a toothed surface of the gear. The nozzle extends in the particular direction, and has a width that is narrower than a gap between tips of the plurality of teeth.

Gear cooling structure

A fuel injection nozzle () of the present invention comprises a pre-mixing passage () which mixes fuel () and air () to generate an air-fuel mixture; and an injection port () which is located downstream of the pre-mixing passage () and injects the air-fuel mixture into a combustion chamber (). The fuel injection port () has a slit shape and a width that is less than a dimension that is twice as large as a quenching distance.

Fuel injection nozzle, fuel injection module and gas turbine

A fuel injector () comprises a cylindrical passage () which opens in a combustion chamber (), a fuel introduction passage () which guides fuel to a region of the cylindrical passage () which is closer to the combustion chamber (), and an air introduction passage () which guides compressed air to the cylindrical passage () at a location that is upstream of a location at which the fuel is introduced to the cylindrical passage (), wherein the fuel introduction passage () guides the fuel in a tangential direction of the cylindrical passage () in a transverse sectional view.

A liquefier system includes: a feed line configured to feed a raw material gas from a raw material supply source such that a pressure of the raw material gas in a predetermined portion of the feed line is kept higher than or equal to a predetermined pressure; a cooling medium circulation line configured to cause a cooling medium to circulate; a static pressure gas bearing configured to be supplied with the gas that has a pressure higher than or equal to the predetermined pressure and to rotatably support a rotating shaft of an expansion turbine; and a bearing supply line configured to connect the predetermined portion of the feed line and a gas inlet of the static pressure gas bearing, such that the gas is supplied to the static pressure gas bearing.

Liquefier system

A turbine generator system includes a turbine power generation unit including a generator and a turbine for driving the generator. The turbine generator system also includes an evaporator, a condenser, a medium feeding pump, a circulating pump, and a feeding passage. The evaporator receives heat from a heat source and supplies a working medium in a vapor phase containing a lubricant to the turbine power generation unit. The condenser condenses the working medium which has flowed through the turbine. The medium feeding pump raises a pressure of the condensed working medium and feeds the working medium to the evaporator, and the working medium extracted from the evaporator is supplied through the feeding passage to bearings in the turbine power generation unit.
