The present invention relates to a ship waste heat power generation system utilizing waste heat from ships. Specifically, the present invention relates to a ship waste heat power generation system utilizing waste heat from ships, wherein recovers exhaust gas waste heat and engine cooling water waste heat from ships using various fuels such as diesel, LNG, and dual-fuel. The recovered waste heat is used as a heat source, while seawater serves as the heat sink, generating electricity through the Organic Rankine Cycle (ORC). By combining exhaust gas waste heat and engine cooling water waste heat, which have different waste heat temperatures, in parallel or series to reduce the evaporation heat capacity, the ORC output is enhanced.

The present invention provides a heat engine operating on a novel closed thermodynamic cycle. The primary characteristics of the heat engine comprise a boiler, condenser, liquid pump, and a regenerative expander in which heat is recovered from the expansion/work extraction process to be returned to the sensible heat addition process that occurs between the condenser outlet and the boiler inlet. The regenerative expander may be comprised of a novel turbine design described as part of the present invention. The primary characteristic of the turbine being a rotor consisting of a hub intersected by a plurality of narrow helical channels through which motive fluid is directed by a plurality of nozzles to induce rotation in the same direction as the helical path of the channels. The liquid pump of the heat engine may also be comprised of a novel design based on similar working principles to the above turbine.

A non-oxygen-consuming energy storage system includes: an interconnecting pipe, connecting a heat recovery boiler or a flue gas header to a chimney or its flue gas duct; a gas inducing equipment along the interconnecting pipe, inducing gas inside the heat recovery boiler to enter the interconnecting pipe through the chimney and then enter the heat recovery boiler; and a heater along the interconnecting pipe and heating up the gas in the interconnecting pipe, and using electricity or other non-oxygen-consuming heating devices as a heat source. Thereby, the gas in the heat recovery boiler is circulated and heated up by the system, and pipelines and components of each unit are kept in a hot standby condition, thus under an emergency power demand on the power grid, the combined cycle unit can rapidly ramp up its load to meet the demand, and can also reduce energy consumption during start-up stage.
