UNDERWATER CRAFT ANAEROBIC POWER PLANT BUILT AROUND STIRLING ENGINE Russian patent published in 2002 - IPC

FIELD: power engineering. SUBSTANCE: invention relates to power plants with Stirling engines designed for operation without communication with atmosphere, for instance, in deepwater apparatus and submarines. Proposed power plant has Stirling engine, sea water main line connected with engine cooling circuit through cold accumulator, cryogenic fuel and cryogenic oxygen tanks, economizer, and cooling unit through which engine cooling circuit passes. Plant has bubbling chamber, steam generator, steam line getting out of steam generator gas part and connected to oxidizer main line by means of ejector. Bubbling chamber is connected with sea water main line and is connected with outboard space by means of pressure line with pump. Sea water main line is furnished with discharge branch with control valve. Tanks with cryogenic fuel components are arranged out of the limits of underwater craft inner space. Liquefied natural gas is used as cryogenic fuel. EFFECT: improved reliability of operation of engine combustion chamber, reduced mass and overall dimensions of plant, provision of explosion and fire safety, reduced cost of operation of deepwater craft. 1 dwg
