POWER SYSTEM BASED ON ORGANIC RANKINE CYCLE PLANT FOR SUBMARINE Russian patent published in 2024 - IPC B63G8/10 B63G8/08 F01K25/10 F02G1/04 

FIELD: ships and other floating facilities.

SUBSTANCE: invention relates to power systems intended for submarines and deep-sea vehicles. Submarine power system operation in submarine surface position is provided by atmospheric air supply for fuel combustion in combustion chamber 2 via atmospheric air supply line 19, discharge of exhaust gases from combustion chamber 2 via main line for discharge of exhaust gases 17 behind hull of submarine 1 and transfer of thermal energy of steam plant 5 from combustion chamber 2 through intermediate circuit 3. Operation of the power system in the underwater position is ensured by dividing the flow of pre-cooled and dried waste gases into two parts, wherein one part of exhaust gases is bypassed via bypass line 22 connected to atmospheric air supply lines 19 and exhaust gas discharge lines 17, into mixing tank 13 to form an artificial gas mixture from the waste gases and oxygen, and the other part of the waste gases is directed through bridge line 27 to liquid-gas ejector 29, which is located on cooling water supply line 34, for dissolution (absorption) in intake water and subsequent removal overboard of submarine.

EFFECT: possibility of creating a single power system intended for operation of a submarine both in surface and underwater position, possibility of operation of the power system on an artificial gas mixture of oxygen and waste gas, as well as increasing the energy efficiency of the organic Rankine cycle unit and reducing the formation of the bubble trail when the submarine moves under water.
