FIELD: gas-turbine plants.
SUBSTANCE: method comprises overexpanding air in a gas-expansion turbine and compressing it in a compressor. Downstream of the turbine the ambient air is cooled by cool air, and moisture is withdrawn. The compressor is actuated from the turbine. The cooling of the ambient air by cool air downstream of the turbine is performed before its supplying to the letter. The moisture is additionally withdrawn from the overexpanded air, and additional compression of the overexpanded air downstream of the compressor up to the pressure of the ambient air is performed in an individual plant.
EFFECT: enhanced efficiency.
