Abstract
A power plant includes an exhaust duct downstream from an outlet of a turbine which receives exhaust gas from the turbine outlet, a first ejector having a primary inlet that is fluidly coupled to a turbine extraction port and an outlet that is in fluid communication with the exhaust duct. The power plant further includes a second ejector having a primary inlet fluidly coupled to the compressor extraction port, a suction inlet in fluid communication with an air supply and an outlet in fluid communication with a suction inlet of the first ejector. The first ejector cools the stream of combustion gas via compressed air extracted from the compressor and cooled via the second ejector. The cooled combustion gas mixes with the exhaust gas within the exhaust duct to provide a heated exhaust gas mixture downstream from the exhaust duct.
