Abstract:
A turbine engine assembly (20) includes a core engine assembly (20) generating an exhaust gas flow (38) and a thermal compressor (44) where the exhaust gas flow (38) from the core engine assembly (20) is received and compressed. The thermal compressor (44) includes a converging duct (46) that recompresses the exhaust gas flow (38) that is mixed with fuel in a secondary combustor (50) and ignited to generate a reheated gas flow (62).
Abstract:
- L'invention porte sur un conteneur (200) d'un système de stockage et de restitution de la chaleur comprenant une enceinte dans laquelle un gaz circule pour être refroidi ou réchauffé. L'enceinte est délimitée par une première enveloppe en béton (203) entourée par une couche isolante thermiquement (206), elle-même entourée d'une coque en acier (204). L'enceinte comporte au moins deux modules (210), comportant chacun une double paroi en béton et un fond perforé (205) délimitant au moins deux volumes (217 et 216) aptes à contenir chacun un lit fixe de particules d'un matériau de stockage et de restitution de chaleur (207). Les modules sont disposés l'un au-dessus de l'autre de manière centrée tel que la double paroi en béton forme la première enveloppe en béton (203) et une deuxième enveloppe en béton (215).
Abstract:
A gas turbine engine includes a first stage compressor, an intercooler in fluid communication with the first stage compressor, and a second stage compressor in fluid communication with the intercooler. The engine also includes a combustor in fluid communication with the second stage compressor and a turbine in fluid communication with the combustor. The intercooler cools an air inflow from the first stage compressor and the recuperator heats the airflow traveling from the second stage compressor to the turbine exhaust. The intercooler and recuperator are arranged radially outward of the combustor.
Abstract:
An object of the present invention is to provide a method and a system for implementing the method so as to alleviate the disadvantages of a reciprocating combustion engine and gas turbine in electric energy production. The invention is based on the idea of arranging a combustion chamber (10) outside a turbine (22) and providing compressed air from serially connected compressors to the combustion chamber in order to carry out a combustion process supplemented with high pressure steam pulses. The combustion chamber (10) is arranged to receive compressed air from each compressing stage of the serially connected compressors (24) for gradually increasing the amount of compressed air in the combustion chamber (10).
Abstract:
The invention relates to a gas turbine (1) which comprises a compressor (2), a central housing (12), at least one combustion chamber (28), an expansion turbine (26), and a heat exchanger (68). Each combustion chamber (28) is fluidically connected to the expansion turbine (26) via an inner housing (24) which is guided through the interior (10) of the central housing (12). The compressor (2) is fluidically separated from the interior (10) of the central housing (12) by an annular collection chamber (16) which is connected to an outlet (8) of the compressor (2) and which has a number of discharge lines (20) which are connected to the cold side (72) of the heat exchanger (68) during operation. Each combustion chamber is designed as a silo combustion chamber (22), and each silo combustion chamber (28) has an inner wall (30), which delimits a combustion chamber (34), and an outer wall (40), and the outer wall (40) surrounds the inner wall (30), thereby forming a cavity (38). The inner wall (30) transitions into the inner housing (24), and the cavity (38) transitions into the interior (10) of the central housing (12).
Abstract:
The method for counteracting draft through an arrangement (1) including a gas turbine (2) during a stop comprises stopping the gas turbine (2) and then equalizing the pressure at least through the gas turbine (2).
Abstract:
A gas turbine engine section (100) includes a plurality of spaced rotor stages (106, 108), with a static guide vane (112) intermediate the spaced rotor stages (106, 108). The static guide vane (112) provides swirl into air passing toward a downstream one of the spaced rotor stages (108), and an outer housing (102) surrounding the spaced rotor stages (106, 108). A diverter (114) diverts a portion of air radially outwardly through the outer housing (102), and across at least one heat exchanger (116, 120). The diverted air passes back into a duct (122) radially inwardly through the outer housing, and is exhausted toward the downstream one of the spaced rotor stages (108).
