| 摘要 |
A gas-turbine installation having a pressurized-air hot-gas generator in which a fuel is reacted with the pressurized air, has a high-pressure turbine-driven compressor and a low-pressure turbine-driven compressor in tandem to supply the compressed air for the gasifier, the turbines being operated by the expanding combustible gases from the gasifier. One or both of the turbines may be provided with electrical generators and/or with starting motors and a steam-generating cycle may be provided for operation by the heat of the combustible gases. The starting system of the invention includes a compressed-air reservoir adapted to be charged by one or both of the compressors during normal operation of the system and capable of stirring a volume of air under such pressure that, for starting the system, the gasifier may communicate with the reservoir to generate sufficient hot combustion gases to drive the turbine.
