CASCADE TURBOJET ELECTRIC GENERATOR Russian patent published in 2024 - IPC F01D1/32 F01D15/10 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering, in particular to electric generators with jet-reactive turbine, which can be used as electric energy generator. Cascade turbojet electric generator contains cascade turbojet drive arranged in housing, and two electric generators. Cascade turbojet drive consists of a jet-reactive turbine containing a shaft with an axial gas supply channel, connected to a pipeline of a gas supply network by a movable coupling with a graphite gas-dynamic seal with a gap between the ends, and rigidly connected to the shaft of radially installed on the hub levers with single-flow channels, connected by outputs with tangentially directed jet nozzles fixed on free ends of levers, and by inputs – with the axial channel of the shaft with formation of a continuous gas path. Shaft is installed in rolling or sliding bearings on supports and has a drive gear for transmission of torque to the shaft of one electric generator. Turboexpander with secondary use of gas coming from jet nozzles is installed on the shaft, which is made with a hub installed on rolling or sliding bearings with possibility of independent rotation on the shaft in the direction opposite to the jet-reactive turbine. Turboexpander has a rim on the inner side of which there are blades installed with a gap to the levers with jet nozzles directed by the jet gas jet into the blades of the turboexpander. On the hub there is a drive gear for transmission of torque to the shaft of the second electric generator. Free ends of levers are interconnected by stiffness ring. Housing of the cascade turbojet drive is tight with an exhaust gas outlet branch pipe for connection to a section of the gas pipeline with low gas pressure, and the axial channel of the shaft of the jet-reactive turbine is connected by a pipeline to the section of the gas pipeline network with a higher gas pressure.

EFFECT: increased efficiency of pipeline gas usage.
