Natural gas and steam combined power generation device for power generation ship

Abstract

The invention discloses a natural gas and steam combined power generation device for a power generation ship, and aims to overcome the defect of low waste heat utilization rate of an existing marine gas generator set. The device comprises a liquefied natural gas storage tank, a regasification buffer tank, a natural gas generator, a steam generator and a waste heat exchanger, a gasification pipeline communicates between the liquefied natural gas storage tank and the regasification buffer tank, and the regasification buffer tank supplies natural gas to the natural gas generator for power generation of the natural gas generator; and flue gas exhausted by the natural gas generator heats the interior of the waste heat exchanger to generate steam, then the flue gas heats natural gas in the gasification channel, the steam generated in the waste heat exchanger is used for power generation of the steam generator, and waste heat of the steam generator heats the natural gas in a gasification channel. The device has the beneficial effects that waste heat generated by the natural gas generator is used for the waste heat exchanger to generate steam which drives the steam generator to work, natural gas and steam combined power generation is formed, and the waste heat utilization rate is high.

AI Technical Summary

Benefits of technology

This patented technology uses two different methods - one method involves burning off excess fuel from an engine's exhaust system when generating electricity without relying solely upon combustion engines or other sources like nuclear energy. Another approach suggests that this was done through another type called waste heat recovery (WHR) systems where it could be useful more effectively than just burning away any unused material during operation.

Problems solved by technology

This technical problem addressed in this patented technology relates to improving how much thermal power can be used during conventional sea-gas generators (NGs) without wasting any useful work on it's own production process.
