FIELD: machine building.
SUBSTANCE: invention relates to the field of machine building, in particular to steam engines operating on heated air/gas, which can be used as replacement of electric motors for drive of various machines and mechanisms of stationary arrangement. System of a combined steam engine of a closed circuit with a heat supply from a steam superheater includes a steam engine combined with a compressor, including a cylinder-piston group, as well as a cylinder head with an intake and exhaust manifold system with a valve mechanism, as well as piston unit of air compressor, driven by units of steam engine, including unit of inlet and unit of outlet of working medium. First circuit of the pipeline passes from the outlet assembly through the oil separator, which excludes the ingress of liquid into this circuit and then into the steam superheater, which is heated from the heat source, and is connected to the inlet manifold of the steam engine for transfer of the working medium heated to the working temperature and circulating in the first circuit of the pipeline. Exhaust manifold is connected to the compressor inlet assembly along the second circuit of the pipeline, at the same time the pipeline on its way additionally passes through the cooler, where the working medium is cooled, an oil separator excluding ingress of liquid into this circuit, a steam chamber, where pressure and temperature in the circuit are lowered and condensate is extracted. System includes a third pipeline circuit passing through the steam engine units for heat removal and its cooling, where this pipeline circuit at the outlet of the steam engine successively passes through the first heat exchanger, the cooler of the second pipeline circuit and the second heat exchanger. Steam engine combined with a compressor comprises an oil circuit configured to pump oil between the corresponding units of the steam engine and the compressor, where the oil circuit includes a moisture separator, which provides separation of liquid from oil, and an oil pump, which pumps oil for its circulation.
EFFECT: higher reliability of system of combined steam engine, stabilization of temperature of units and working medium in its circuits at its high efficiency.
