FIELD: engines and pumps.
SUBSTANCE: proposed unit comprises compressor, gas turbine drive, gas-to-oil heat exchanger, bearing lubrication and cooling system circuit made up of oil lines, oil filter, gas-to-oil heat exchanger, oil tank with oil heater, oil temperature gages, and circuit to feed fuel gas into combustion chamber made up of gas lines, gas filter, gas-to-oil heat exchanger, gas heater, gas pressure regulator and gas temperature control gage. Aforesaid bearing lubrication and cooling system circuit has oil line to feed oil into gas-to-oil heat exchanger and that of oil discharge from said gas-to-oil heat exchanger are communicated by bypass oil line accommodating controlled regulation valve opening on starting the unit. Gas line to feed gas into gas-to-oil heat exchanger and that of gas discharge from gas-to-oil heat exchanger are communicated by bypass gas line accommodating control valve.
EFFECT: reliable operation of gas turbine drive.
