摘要： In a gas turbine, having a number of turbine blades/vanes respectively combined to form blade/vane rows, each of the turbine blades/vanes including an integrated cooling air duct, the cooling air requirement is to be kept particularly low in conjunction with reliable cooling of the turbine blades/vanes. For this purpose, the turbine blades/vanes forming a first turbine blade/vane row and the turbine blades/vanes forming a second blade/vane row connected downstream thereof, viewed in the flow direction of the working medium, are connected one behind the other on the cooling air side with the intermediate connection of an injection device for water. During the operation of the gas turbine, the cooling air flowing out of the turbine blades/vanes forming the first blade/vane row is intercooled by the injection of water and is subsequently supplied to the cooling air ducts of the turbine blades/vanes forming the second blade/vane row.

摘要： The efficiency and capacity of an air compressor (10) (FIG. 1) are increased by pre-cooling the inlet air to below the dew point in air chiller (11), and then injecting the resulting condensate into the chilled air in the form of fog-sized droplets in a fogger (16). The advantages extend to combustion engines, and especially to regenerative combustion turbines.

摘要： Apparatus for generating power includes a gas turbine unit having a compressor for compressing ambient air and producing compressed air, a combustion chamber to which the compressed air is supplied, a source of relatively high grade fuel for burning in the combustion chamber and producing combustion gases, and a gas turbine connected to generator and to the compressor for expanding the combustion gases and producing exhaust gases. The apparatus further includes a combustor that burns relatively low grade fuel, and produces combustion products, and an indirect contact heat exchanger responsive to the combustion products for heating the compressed air before the latter is applied to the combustion chamber, and for producing cooled combustion products. In addition, an energy converter is provided having an organic working fluid responsive to the exhaust gases for converting heat in the exhaust gases to electricity. Finally, the apparatus of the invention serves to minimize the consumption of high grade fuel in the presence of changes in the heating value of the low grade fuel.

摘要： A gas turbine power plant operating on a dual Brayton cycle and utilizing a circulating pressurized fluidized bed combustor is disclosed. An open Brayton cycle is provided in which the hot flue gas from the fluidized bed combustor is expanded to extract work to drive compressors to supply combustion air for the fluidized bed combustor and to drive an electric generator to produce electricity. The residual heat of the flue gas exhausted from the open Brayton cycle can be utilized for heat cogeneration at high power-to-heat ratios. A closed Brayton cycle is also provided, the working medium of which is heated in an indirect heater of the circulating pressurized fluidized bed combustor and expanded to extract work to drive another electric generator. The air supplied by the open Brayton cycle is also used to fluidize the heated particles in the indirect heater. The power plant is capable of burning a wide variety of fuels, operating over a broad size range, and minimizing pollution while providing highly efficient, low cost electric power and heat production.

摘要： A compressed air energy storage (CAES) system utilizes compressed air stored in a cavity for electric power and cold production. During periods of excess power production, atmospheric air is compressed then cooled in stages using energy from a motor/generator. Condensed water is then separated from the air which is then stored in a cavity. When there is an energy demand from the CAES system, the stored compressed air is heated using heat from an external low grade energy source such as refrigerated substances, surrounding water, surrounding air, waste heat sources and solar energy. The heated compressed air is then expanded through a plurality of expansion stages to provide mechanical power to the motor/generator for generating electricity.

摘要： A process for producing mechanical power utilizing compressed and humidified hot air and a fuel, which are mixed together and combusted and the resulting hot combustion gas is expanded through a gas turbine. The air is initially compressed and intercooled against a water stream, and then further compressed and passed directly to a heat recovery unit where it is humidified using the water from the compressed air intercooling step. The compressed humidified air is further heated against hot turbine exhaust gas and combined with a fuel in a combustor, and the resulting hot combustion gas is expanded through a gas turbine to produce mechanical power needed for driving the air compression. The hot turbine exhaust gas is cooled countercurrently against the compressed humidified air stream and against the water stream, and then discharged to the atmosphere. By eliminating a usual separate air aftercooling and saturator unit upstream of the air combined humidifying and heating step, process thermal efficiency for the present process is increased and equipment cost reduced.

摘要： A turbo-machine plant comprises a gas turbine connected to a synchronous electrical machine by way of an over-riding clutch and a compressor connected to the electrical machine by way of a disconnectible coupling. The machine group is operable in two different modes. In one mode, the electrical machine functions as a motor for driving the compressor which delivers air to an air storage chamber and the gas turbine is automatically disconnected from the electrical machine by the over-riding clutch. To change over to the other operational mode the power absorption of the compressor is first reduced to a low level, and the gas turbine is then brought up to synchronous speed and becomes coupled to the electrical machine which then operates for current generation.
