FIELD: power engineering. SUBSTANCE: outside air "A" is compressed in compressor of gas- turbine plant 1 and after heating in combustion chamber 4 it is fed to turbine of gas generator. Air may be also heated in heaters 2 powered by solar reflectors 3. Outside air is expanded by flow "C" in turbine 7 of evacuating unit 6 to pressure below atmospheric and at temperature of about -53 to -70 C it is fed to first heat exchanger 9 where outside air flow D is cooled; this flow is fed by one of fans 10 driven by turbine from flow B. Heated air enters vacuum compressor 8 where it is compressed to outside pressure. Power shortage between expansion work on turbine 7 and compression work on compressor 8 is made good by turbine 5 mounted on shaft 6. Refrigerating capacity of air after reexpansion turbine 7 is sufficient for forming 7 to 10 flows more. In cooling any flow, air passes through dew point causing separation of moisture. Air cooled to dew point and dehydrated as a result and then cooled below dew point in each heat exchanger is used as coolant for subsequent heat exchanger. EFFECT: obtaining water condensate from outside air in industrial scales. 3 cl, 1 dwg |
