FIELD: power industry.
SUBSTANCE: invention relates to a device for electric energy generation in a gas turbine. The essence of the invention: the device includes multiple thermoelectric elements (44) having a surface enveloping a heat source (SC). The heat source is formed with annular zones, in which some part of exhaust gas passes, which forms a hot fluid medium, along a spiral trajectory to the outer side of the annular zones. A cold source is formed with the annular zones, along which the cold fluid medium passes along a spiral trajectory to the centre of a turbine nozzle. At least one annular assembly of the thermoelectric elements is installed concentrically so that one of the surfaces of the assembly is in contact with the cold fluid medium, and the other surface is in contact with the hot fluid medium, thus a cylindrical counter-flow heat exchanger is provided.
EFFECT: improved efficiency.
