Abstract: In a power plant which consists essentially of a compressor (2), of a downstream combustion chamber (6) and of a turbine (8) acting downstream of the combustion chamber, a first injector system (5a) is provided in the region of the outlet diffusor (4) of the compressor (2). A second injector system (5b) acts upstream of a burner (100) of the combustion chamber (6). The driving nozzles of these injectors are loaded by steam (10, 10a) from a waste-heat steam generator (13). In the first injector system (5a), precompressed air from the compressor (2) flows into the catching nozzle; a liquid fuel (112) flows upstream of the burner (100) into the catching nozzle of the second injector system (5b).

Abstract: In an air reservoir turbine, comprising a gas turbine group connected for selectable delivery of compressed air from a compressor unit and a compressed air reservoir, and including a hot water reservoir and a waste heat steam generator downstream of the gas turbine group, an amount of steam from the waste heat steam generator is introduced into the gas turbine group and is used for increasing its output. Additionally, hot water from various intercoolers and a heat exchanger is generated in connection with the compressor unit of the gas turbine group. The amount of steam obtained therefrom is admixed to the compressed working air and is used as combustion air for operating the gas turbine group.

Abstract: In a method for regulating a gas-turbine assembly, essentially consisting of a compressor unit (1), of an HP-combustion chamber (4), of an HP-turbine (6), of an LP-combustion chamber (9), of an LP-turbine (12) and of a generator (14), the rating of the fuel quantity (FH) for the HP-combustion chamber (4) is carried out responsive to a corrected temperature signal which is formed by the value of the temperature (T13) at the outlet of the LP-turbine (12), reduced by the particular temperature rise (.DELTA.T) detectable there. This temperature signal (T13-.DELTA.T) is recorded in that the temperature rise (.DELTA.T) generated by the fuel quantity (FL) introduced into the LP-combustion chamber (9) is subtracted from the measured temperature at the outlet of the LP-turbine (12). The uncorrected temperature signal at the outlet of the LP-turbine (12) is used for rating the fuel quantity (FL) for the LP-combustion chamber (9).

Abstract: A method of establishing part-load operation is proposed for a turbine group. This gas turbine group consists essentially of a compressor unit (1), of an HP combustion chamber (4) downstream of the compressor unit (1), of an HP turbine (5) downstream of this HP combustion chamber (4), of an LP combustion chamber (8) operating by self-ignition and arranged downstream of the HP turbine (5), the hot gases (10) of which LP combustion chamber (8) being admitted to an LP turbine (11). The temperature at outlet from the HP turbine (5) remains essentially the same due to the reduction of the fuel quantity in the LP combustion chamber (8) to zero. Furthermore, the fuel quantity of the HP combustion chamber (4) remains approximately constant during the reduction of the fuel quantity in the LP combustion chamber (8) so that the temperature at inlet to the HP turbine (5) likewise remains constant.

Abstract: The invention relates to a method for operating a turbocompressor (12) having at least two compressor stages and a cooler (14) to which water is applied as coolant, the heated cooling water having a pressure exceeding the saturation pressure, with the result that said cooling water is partially evaporated in an evaporation vessel (30) at an intermediate pressure level less than the saturation pressure. The steam thus produced evacuates by means of an ejector (34) a second evaporation vessel (32), in which a proportion of the residual water of the first vessel (30) is, in turn, evaporated and the remaining water is cooled below 100.degree. C.

Abstract: A method and apparatus for a combined turbine installation includes a gas turbine group with a compressor having a water cooler, a combustion chamber and a gas turbine, and having a steam turbine installation with a waste heat boiler heated by the exhaust gas from the gas turbine. The waste heat boiler includes an evaporator, drum, enconomizer and superheater, a steam turbine downstream of the waste heat boiler and a combined feed water tank/flash evaporator unit. The feed water tank/flash evaporator is supplied with condensate from a condenser fitted downstream of the steam turbine. Cooling water heated by the compressed air is evaporated in at least one state and the steam produced is fed to the waste heat boiler for further heating, or directly to the steam turbine. In addition, the unevaporated residual water is fed to the feed water tank/flash evaporation unit, and after mixing with the condensate from the steam turbine, is supplied to the compressor cooler.

Abstract: In a method for operating a gas turbine group (32) having an integrated steam process (33) and having an air storage installation (34), a partial mass flow (17) is extracted from a high-pressure turbine (15) of the gas turbine group (32) and passed through a heat exchanger (20) for cooling one or a plurality of structures of the gas turbine group (32). This heat exchanger (20) is operated by a cooler medium (4, 6). The partial mass flow (17) cooled in this way is subsequently passed through the structures (18, 19) to be cooled of the gas turbine group (32). By this means, the cooling is achieved of, in particular, the structures installed downstream of the high-pressure turbine (15). The heat generator (18) connected downstream and the low-pressure turbine (19) can be connected in parallel or in series. It is therefore possible to achieve cooling of the loaded structures of the gas turbine group (32) without, in the process, affecting the working gas balance of the installation.

Abstract: In a method of operating a gas turbine group (34) with or without integrated steam process (20) and with or without an air reservoir installation (20), a series connection with one and the same air mass flow (16, 17) is used for cooling one or more structures (15, 18, 19) which are in effective connection with the mass flow of the gas turbine group (34), the cooling air mass flow being extracted from a position which has a sufficiently low temperature.

Abstract: In a combined gas/steam power station plant which consists essentially of a fossil-fired gas turbine group and a steam circuit, with an exhaust heat boiler (11) in between, intercooling and reheat are provided to maximize the efficiency. The gas turbine group consists of two compressors (1, 2), of two combustion chambers (7, 9) and of two turbines (8, 10). Downstream of the first compressor (1), there is an intercooler (3) and on the cool side of this is placed an evaporator (4) which is in effective connection with the intercooler. The steam quantity formed in the evaporator (4) is introduced into a turbine (6) of the steam circuit, the result of this being a first improvement in efficiency. Downstream of the first turbine (8), there is a second combustion chamber (9) in which the exhaust gases from the first turbine (8) are processed to produce hot gases for the second turbine (10) .
