ANAEROBIC POWER PLANT WITH STIRLING ENGINE FOR UNDERWATER CRAFT Russian patent published in 2002 - IPC

FIELD: power engineering. SUBSTANCE: invention relates to power plants with Stirling engines designed for mounted in craft 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 heat exchanger-cooler through which sea water main line passes, and also separator and compressor, the latter being furnished with bypass line. Tanks with cryogenic components of fuel are arranged outside craft inner space, and sea water main line passes successively through cold accumulator and heat exchanger-cooler. Liquefied natural gas is used as cryogenic fuel. EFFECT: improved reliability of operation of engine combustion chamber, reduced mass and overall dimensions, simplified design of plant, provision of explosion and fire safety and cut down cost of operation. 1 dwg
