Abstract:
1. A semiclosed cycle Brayton power system comprising: a storage tank/separator containing carbon dioxide; a compressor connected to said storage tank/separator to receive and compress said carbon dioxide; a regenerator connected to said compressor to receive and to partially heat said compressed carbon dioxide; an O a diesel fuel tank with means for storing water therein separate from diesel fuel provided therein; a combustor connected to said regenerator and said O a turbine in communication with said combustor for receiving and expanding said heated working fluid; a power transfer means connected to said turbine to allow power to be withdrawn from said power system, said power transfer means being further connected to said compressor to enable said turbine to drive said compressor; said regenerator connected to said turbine for receiving said expanded working fluid and utilizing said expanded working fluid for said partial heating of said carbon dioxide; a cooler connected to said regenerator for receiving and cooling said expanded working fluid and condensing said working fluid into gaseous carbon dioxide with water droplets entrained therein; and said storage tank/separator being connected to said cooler for receiving said water and said gaseous carbon dioxide and separating said water from said gaseous carbon dioxide, said storage tank/separator further being connected to backfill said diesel fuel tank with said separated water.
