FIELD: heat power engineering.
SUBSTANCE: invention can be used in drives for electric generator. GTU contains air compressor, gas turbine, payload, installed on one shaft, and is characterized by presence of external heater of working medium and device for formation of gas flows during preparation of working medium and cooling of gas turbine plant located between compressor and gas turbine.
EFFECT: invention allows modernizing existing gas turbine units for operation on compressed air heated by heat during combustion of any types of fuel, at that, enabling improvement of environmental situation in the GTU operation area due to reduction of emissions to the environment of hazardous substances from fuel combustion.
