摘要： PURPOSE: To sufficiently lubricate a surface of a swash plate at start of a compressor by providing a sub-oil sump at the lower part of a swash plate for dipping the lower part of the swash plate in an oil deposited therein at stop of the compressor and feeding back an oil deposited in auxiliary oil chambers during operation of the compressor into the sub-oil sump while the compressor rests.
CONSTITUTION: A sub-oil sump chamber 21 is provided at the lower part of a swash plate 13, that is, between mutually adjacent two bores of left and right cylinder blocks 2, 3, constituted in such a manner that the lower part of the swash plate 13 with an oil deposited therein is dipped while a compressor rests. A part of the oil floating in the state of mist in the sub-oil sump chamber 21 passes through communication holes 29, 30 into auxiliary oil chambers 25, 26 disposed around the sub-oil sump chamber 21 and is gradually concentrated and deposited therein. When the compressor stops, no oil enters the auxiliary oil chambers 25, 26 through the communication holes 29, 30 from the sub-oil sump 21 and the oil in the auxiliary oil chambers 25, 26 goes slow into the sub-oil sump 21 through small openings 27, 28. As sufficient oil in the sub-oil sump chamber 21 is ensured at start of the compressor, the surface of the swash plate may be well lubricated.

CONSTITUTION:The intermediate heating medium, heated by a waste heat fluid 1 in an intermediate heating medium heater 2, is allowed to exchange heat with a low boiling point medium by a direct contacting heat exchanger 7. Condensed liquid of the low boiling point medium is injected by an injection nozzle 19 into the direct contacting heat exchanger 7, with an ascending current caused by an air foam produced when evaporated, and a circulation of the intermediate heating medium is generated. And for the lubrication of a low boiling point medium turbine 10, a reduction gear 22 and a generator 11, the intermediate heating medium in the direct contacting heat exchanger 7 is partially taken out, and led to an intermediate heating medium cooler 15 through a bearing valve 16, and distributed after cooling the liquid condensated of low boiling point medium, to every part, and returned to the direct contacting heat exchange 7 after lubrication.

摘要： PURPOSE:To raise the circulating force of hot fluid and cold fluid and the heat exchange capacity, by ejecting the hot fluid and the cold fluid in the same direction in a direct heat exchanger. CONSTITUTION:In the direct heat exchanger 1, the hot fluid and the cold fluid are ejected upward in the same direction from hot fluid nozzles 4 and cold fluid nozzles 5. The cold fluid is evaporated by the heat of the hot fluid so that bubbles 6 are made from the evaporated cold fluid. When the bubbles 6 float up, the bubbles have a driving force to move the hot fluid in the same direction. Then, the bubbles 6 are supplied to a heat load through a pipe 31. The temperature-reduced hot fluid is conducted through a pipe 25 to a cooler 8 which is cooled by the cold fluid 3. Thereafter, the hot fluid is introduced into a heater 11 heated by a heating fluid 10. The heated hot fluid is conducted again to the nozzles 4.

摘要： PURPOSE:To minimize heat loss incurred at a transition piece, by a method wherein, in a catalyst combustion system combustion device, flaming lean gas phase combustion is conducted by a burner to reduce production of NOX, and oxidization is made in the transition piece by means of a catalyst. CONSTITUTION:A combustor B is constituted such that it consists of a sub- combustion chamber 1 and a main combustion chamber 2, the size of the sub- combustion chamber 1 is decreased over that of the main combustion chamber 2, an axial revolving device 3 and a radial revolving device 5 are mounted, and lean gas phase combustion can be effected in the sub-combuston chamber 1. This causes shortening of a flame which is formed only in the sub-combustion chamber 1. As fuel is gradually increased, a flame is gradually extended to the main combustion chamber 2. Gas, flowing out of the combustor B, is slightly decreased in temperature by means of the air fed through diluting holes 7A and 7B to oxidize CO, HC by means of an oxidizing catalyst 10 in a transition piece TR, and produces high temperature gas which is fed to a turbine T. This permits minimization of heat loss incurred at the transition piece.

摘要： PURPOSE:To effectively perform the cooling of a liner and improve the strength of the liner against the combustion vibration and the like by providing ridges inclined with respect to the axial direction on the peripheral surface of the liner of the gas turbine driven at high temperatures and under high pressures. CONSTITUTION:For example, V-shaped groovelike ridges 6 and 7 are projected and formed at the combustion gas flowing side along stright line or a curve inclined with respect to the axial direction, at the outside liner 2 and inner side liner 3 in an annular gas turbine combustion apparatus. In the outside liner 2, the ridge 6 is formed from the intermediate part, and an air hole 9 for cooling and air introduction is applied to the ridge 6. In the inside liner 3, the ridge 7 is provided in a circulating region immediately after an air turning device 5 provided around the periphery of a fuel nozzle 4. These ridges 6 and 7 have projection heights higher as they come downstream in which the air turning flow due to the turning device 5 vanishes, so that a turning flow is produced, and thus effective cooling becomes possible.

CONSTITUTION:Heat in waste heat fluid 1 is made heat exchange with intermediate heat medium in an intermediate heat medium heater 2 and heated, then the heated medium comes into a direct type heat exchanger 7 along with being made heat exchange with low boiling point medium. Here, evaporated low boiling medium is arrived through a system 8 to a turbine 10, which drives a dynamo 11. After steam coming out of the turbine 10 has been condensed by a condenser 13 which is cooled off by a cooling water system 12, it is returned through an intermediate heat medium cooler 15 to said heat exchanger 7. In this case, incorporative structure is made such as to hold said intermediate heat medium heater 2, the direct type heat exchanger 7, the turbine 10, the dynamo 11 and the condenser 13 into one closed vessel.
