TL;DR: In this paper, an afterburner device (40) is connected into the exhaust line (20) between the gas turbine (10) and CO2 separation device (30) by fluid technical means, which device is designed to afterburn fuel, particularly fossil fuel, with the addition of exhaust gas.
Abstract: A gas turbine plant (1) comprising at least one gas turbine (10) with a compressor stage (11) and an expansion stage (12), an exhaust gas line (20) to guide the flow of exhaust gas exiting from the expansion stage (12) during operation of the gas turbine (10) and a CO2 separation device (30) connected by fluid technical means to the exhaust gas line (20) for the separation of at least a part of the CO2 contained in the guided exhaust gas, wherein an afterburner device (40) is connected into the exhaust line (20) between the gas turbine (10) and CO2 separation device (30) by fluid technical means, which device is designed to afterburn fuel, particularly fossil fuel, with the addition of exhaust gas, and wherein the afterburner device (40) is a gas turbine (40) which has an expansion stage (42) which permits only expansion to a pressure level which lies above the pressure level of the exhaust gas introduced into the compressor stage (41) of the gas turbine (40) concerned.

TL;DR: In this paper, a solid fuel tad-turbine plant containing compressor, turbine, payload located on same shaft, solid fuel combustion chamber made as installed in series gasifier, afterburner and mixer, an heat-exchanger.
Abstract: FIELD: power industry.SUBSTANCE: invention relates to power industry. The solid fuel tad-turbine plant containing compressor, turbine, payload located on same shaft, solid fuel combustion chamber made as installed in series gasifier, afterburner and mixer, an heat-exchanger. The compressor is made with atmosphere air inlet and outlet, connected to input of cold loop of the heat-exchanger. Output of cold loop of the heat-exchanger is connected with the turbine input, turbine output is connected with air supply line to combustion chamber made as three pipelines with chokes installed in air supply pipelines to mixer and afterburner. The chokes installation in air supply pipelines to mixer and afterburner determines minimum hydraulic losses via the gasifier, thus ensuring maximum efficiency of the plant.EFFECT: invention reduces losses in gas-turbine tract, excludes abrasive wear-out of the flow part of the plant, and increases of the entire plant efficiency.3 cl, 1 dwg

TL;DR: In this article, the performance of air-breathing engines (ABEs) for horizontal take-off and landing SSTO vehicle is investigated. And the performance with respect to thrust and specific fuel consumption of turboengines based on various technologies, including a turbojet with and without afterburner (TJ), turboramjet, and air-turbo-ram jet engines are compared.
Abstract: Various concepts of air-breathing engines (ABEs) that could be used for a horizontal take-off and landing SSTO vehicle are investigated. The performances (with respect to thrust and the specific fuel consumption) of turboengines based on various technologies, including a turbojet with and without afterburner (TJ), turboramjet, and air-turbo-ram jet engines are compared. The mission capabilities of these ABEs for SSTO and TSTO vehicles is examined in terms of the ratio of the effective remaining weight (i.e., the weight on the orbit) to the take-off gross weight, using two-dimensional flight analysis. It was found that the dry TJ with the turbine inlet temperature 2000 C is one of the most promising candidates for the propulsion system of the SSTO vehicle, because of its small weight and high specific impulse. 6 refs.

TL;DR: In this article, the afterburner collector and nozzles are cleaned using a reference filter, which is periodically checked for particles of coke deposits in it, and by their presence in the filter the level of the manifold cleaning is obvious.
Abstract: FIELD: engines and pumps.SUBSTANCE: method comprises the fuel pressure measurement in the afterburner manifold of the engine which is performed periodically, comparison of the obtained value of fuel pressure in the afterburner manifold of the engine with the maximum allowable one, which is pre-set for this type of engines, and at excess of the latter - cleaning of the afterburner collector and nozzles. Medium from its internal cavity is evacuated by means of evacuation device, for example a vacuum pump, and the pressure created by the evacuation device is changed periodically. Medium is passed through the reference filter which is periodically checked for particles of coke deposits in it, and by their presence in the filter the level of the manifold cleaning is obvious. The manifold cavity is filled with flushing liquid and after holding it is removed from the manifold internal cavity towards the direction, opposite to fuel supply, meanwhile for flushing liquid it is possible to use the flushing liquid TSR-5050 or ZOK-27. The cleaning on the working engine is performed for this purpose the engine is brought to the low acceleration mode, then by increase of rotor rotation speed they are brought to the maximum unboosted mode, maintained in it and the rotor rotation speed reduced down to the low acceleration mode. The maximum allowable value of pressure in the manifold of the afterburner is obvious by pressure in the manifold at minimum allowable fuel consumption through the clogged fuel manifold, at which normal functioning of the afterburner chamber without blackout and loss of traction is ensured.EFFECT: improvement of quality of cleaning of manifold and nozzles without engine disassembly.8 cl, 1 dwg
