Abstract: A turbomachine includes a compressor configured to compress air received at an intake portion to form a compressed airflow that exits into an outlet portion. A combustor is operably connected with the compressor, and receives the compressed airflow. A turbine is operably connected with the combustor, and receives the combustion gas flow. The turbine has a plurality of wheels and a plurality of buckets. The turbine receives compressor bleed off air to cool the wheels and buckets. A cooling system is operatively connected to the turbine. The cooling system includes a plurality of heat pipes located axially upstream of at least one of the wheels. The heat pipes are operatively connected to a bearing cooler system. The heat pipes and the bearing cooler system are configured to transfer heat from the compressor bleed off air to one or more heat exchangers.

Abstract: A power generation system may include: a first gas turbine system including a first turbine component, a first integral compressor and a first combustor to which air from the first integral compressor and fuel are supplied. The first integral compressor has a flow capacity greater than an intake capacity of the first combustor and/or the first turbine component, creating an excess air flow. A second gas turbine system may include similar components to the first except but without excess capacity in its compressor. A turbo-expander may be operatively coupled to the second gas turbine system. Control valves may control flow of the excess air flow from the first gas turbine system to at least one of the second gas turbine system and the turbo-expander, and flow of a discharge of the turbo-expander to an inlet of at least one of the first integral compressor and the second compressor.

Abstract: A power plant includes a compressor, a combustor downstream from the compressor and a turbine disposed downstream from the combustor. The compressor includes a compressor extraction port. The turbine includes a turbine extraction port that is in fluid communication with a hot gas path of the turbine and which provides a flow path for a stream of combustion gas to flow out of the turbine. An exhaust duct is disposed downstream from the turbine and receives exhaust gas from the turbine. A static mixer coupled to the turbine extraction port and to the compressor extraction port cools the stream of combustion gas upstream from the exhaust duct. The cooled combustion gas flows into the exhaust duct at a higher temperature than the exhaust gas and mixes with the exhaust gas within the exhaust duct to provide a heated exhaust gas mixture to a heat exchanger downstream from the exhaust duct.

Abstract: A power plant includes a gas turbine having a combustor downstream from a compressor, a turbine disposed downstream from the combustor and an exhaust duct downstream from an outlet of the turbine. The combustor includes an extraction port that is in fluid communication with a hot gas path of the combustor. The extraction port defines a flow path for a stream of combustion gas to flow out of the hot gas path. The exhaust duct receives exhaust gas from the turbine outlet. A coolant injection system injects a coolant into the stream of combustion gas upstream from the exhaust duct such that the stream of combustion gas blends with the exhaust gas from the turbine within the exhaust duct and forms an exhaust gas mixture within the exhaust duct. A heat exchanger is disposed downstream from the exhaust duct and receives the exhaust gas mixture from the exhaust duct.
