专利汇可以提供Combined gas-steam turbine power plant专利检索，专利查询，专利分析的服务。并且In a combined gas-steam turbine power plant, part-load heat rate is improved by recirculating the boiler stack gas into the air inlet of the turbine compressor section.，下面是Combined gas-steam turbine power plant专利的具体信息内容。
1. A combined steam turbine-gas turbine power plant comprising: a gas turbine having in series a compressor section, a combustion chamber, and a turbine section discharging hot exhaust gases, a steam generator comprising means for containing water, means for conducting the heat from said hot exhaust gases to the water in said containing means, and outlet means for said exhaust gases following said conducting means, a steam turbine receiving steam from said steam generator, and means for introducing at least part of the exhaust gases from said outlet means into the compressor section including means for combining said exhaust gases with ambient air, and means responsive to the temperature of the gas-air mixture entering the compressor section for regulating the flow of exhaust gases into said combining means and thereby regulating the temperature of the gas-air mixture.
2. A power plant according to claim 1 in which said means for introducing at least part of the exhaust gases into the compressor section comprises filtering means between said combining means and said compressor section.
3. A power plant according to claim 1 in which said outlet comprises a stack for receiving the exhaust gases discharged from said conducting means and exhausting said gases to the atmosphere, means for producing a back-pressure in said stack, and means communicating with said stack for delivering at least part of the exhaust gases in said stack to said compressor section under the influence of said back-pressure.
4. A combined steam turbine-gas turbine power plant comprising: a gas turbine having in series a compressor section, a combustion chamber, and a turbine section discharging hot exhaust gases, a steam generator comprising means for containing water, means for conducting the heat from said hot exhaust gases to the water in said containing means, and outlet means for said exhaust gases following said conducting means, a steam turbine receiving steam from said steam generator, and means for introducing at least part of the exhaust gases from said outlet means into the compressor section, said outlet means comprising a stack for receiving the exhaust gases discharged from said conducting meanS and exhausting said gases to the atmosphere, an adjustable damper for producing a back-pressure in said stack, and means communicating with said stack for delivering at least part of the exhaust gases in said stack to said compressor section under the influence of said back-pressure.
5. A combined steam turbine-gas turbine power plant comprising: A gas turbine having in series a compressor section, a combustion chamber, and a turbine section discharging hot exhaust gases, a steam generator comprising means for containing water, means for conducting the heat from said exhaust gases to the water in said containing means, a steam turbine receiving steam from said steam generator, a stack for receiving exhaust gases from said turbine section and from said conducting means, means establishing a path for flow of atmospheric air into said compressor section, filtering means in said path, means preceding said filtering means in said path for combining exhaust gases from said stack with the atmospheric air entering the compressor section through said filtering means, means for producing a back-pressure in said stack, means communicating with said stack for delivering at least part of the exhaust gases in said stack to said combining means under the influence of said back-pressure, means responsive to the temperature of the gas-air mixture entering the compressor section for regulating the flow of exhaust gases into said combining means and thereby regulating the temperature of the gas-air mixture.
