Abstract
A power plant especially for the propulsion of waterborne vehicles, includes two prime movers, a gas turbine (1) and a diesel starting engine (3) for selectively driving, via a central gearbox (4) and clutches (7) and (9), a power output shaft (5) and a generator (6). The gas turbine (1) is driven by a piston-like compressor (2) via central gearbox (4) and clutches (7) and (8), and further includes a turbocharger (12) and an intercooler (13) connected between the outlet of turbine (1) and the inlet of compressor (2). The diesel engine (3) drives auxiliary electric generator (17). The power output shaft drives a propeller (19) through a bearing (11). The shaft generator (6) is stabilized by a flywheel (22).
Claims17
A gas turbine power plant, comprising:
- a gas turbine including a plurality of combustion chambers;
- a piston-type air compressor mechanically connected to the gas turbine and driven by it;
- and
- a plurality of pipes connected between the air compressor and the combustion chambers, the air compressor supplying compressed air to the combustion chambers of the gas turbine through the pipes.
A gas turbine power plant, comprising:
- a gas turbine including a plurality of combustion chambers;
- a piston-type air compressor mechanically connected to the gas turbine and driven by it through a gearbox, the gas turbine and compressor each connected to the gearbox through a selectively engageable and disengageable shaft-coupling clutch;
- an output shaft connected to the gearbox such that the output shaft is driven by the gas generator;
- an engine for starting the gas turbine power plant, the engine being connected to the gearbox through a selectively engageable and disengageable shaft-coupling clutch;
- and
- a plurality of pipes connected between the air compressor and the combustion chambers, the air compressor supplying compressed air to the combustion chambers of the gas turbine through the pipes.
In a gas turbine power plant having a source of compressed air and a source of fuel, the compressed air and fuel being combined in a plurality of combustion chambers and combusting therein to produce combustion gases that drive a gas turbine, the improvement comprising:
- using a piston-type air compressor as the source of compressed air rather than a turbo-compressor, the piston-type air compressor being mechanically connected to the gas turbine and driven by it.
