FIELD: power engineering.
SUBSTANCE: combined utilization energy gas turbine installation of the compressor station of the main gas pipeline consists of a drive gas turbine unit of a recycling gas turbine plant. Drive gas turbine plant comprises a gas generator, a power gas turbine, a supercharger of natural gas, a regenerative heat exchanger installed in the exhaust gas duct of a power gas turbine. Recycling gas turbine unit incorporates a compressor, a combustion chamber, a power gas turbine, an electric generator and a heat exchanger. Output of the power gas turbine is connected with the atmosphere through a regenerative heat exchanger. Outlet of the compressor of the utilization gas turbine plant is connected by a pressure duct and a compressed air pipe through the heat exchange surface of the regenerative heat exchanger and a combustion chamber of an exhaust gas turbine unit with a gas turbine of a recycling gas turbine plant equipped with an additional regenerative heat exchanger and an additional compressed air pipeline. Additional regenerative heat exchanger is installed in the exhaust gas flue of a gas turbine of a utilization gas turbine plant. Outlet of the compressor of the utilizing gas turbine plant is connected by an additional compressed air pipeline through the heat exchange surface of the additional regenerative heat exchanger and the pipeline of heated compressed air with the combustion chamber of the utilization gas turbine unit.
EFFECT: invention is aimed at increasing the electric power of a utilizing power gas turbine plant.
