Abstract

1,173,923. Turbine power plant. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept.6, 1967 [Sept. 29, 1966], No.43614/66. Headings F1G and F1Q. A method of restarting a gas turbine 1 by means of a steam turbine 2 comprises storing, during an idle period of the gas turbine, a quantity of steam which is generated in a boiler 4 heated with gas from the exhaust of the gas turbine when working and deriving from the stored quantity at least a major part of the power required for accelerating the gas turbine by means of the steam turbine to a self sustaining speed. The steam is stored in a heat insulated vessel 3A which discharges directly through appropriate control valves to the steam turbine 2. A flash boiler 3B supplements the stored steam and supplies air ejectors 2A and sealing glands 2B. The boiler 4 includes a feedwater pre-heater 4A receiving steam remaining in vessel 3A immediately after a starting operation. In a modification. Fig.2 (not shown), the steam storage vessel 3A contains an electric heater (3c) to compensate for heat losses. In this case no flash boiler 3B is provided and the air ejectors 2A are supplied from the storage vessel 3A. The latter receives charging steam from the boiler 4 via the expansion chamber of turbine 2. The storage vessel may alternatively be formed by a high temperature water accumulator capable of releasing steam or by a steam accumulator forming part of the boiler 4. The shaft connecting the turbines 1, 2 may include a clutch so that when the plant is about to be shut down the steam turbine 2 can be stopped and an accumulation of steam built up for the restarting operation. Alternatively, the turbines 1, 2 may be on separate shafts, normally unconnected or geared together to give a common power output. In a further modification, the steam turbine 2 drives the gas turbine 1 only at starting but during normal running drives a compressor stage feeding the gas turbine. Alternatively, the steam turbine may drive a generator which supplies an electric starting motor driving the gas turbine.
