The invention discloses a ship LNG fuel low pressure gas supply system. The ship LNG fuel low pressure gas supply system comprises an LNG storage tank arranged on a ship and an LNG filling technology system connected to the LNG storage tank through a pipe and a valve and a gas supply system, and the gas supply system is connected to a gas engine on the ship through a pipe and a valve; the LNG filling technology system comprises an LNG storage tank inerting pipeline system, a gas replacement pipeline system, an LNG storage tank precooling pipeline system and an LNG filling pipeline system, the gas supply system is used for pressurizing, gasifying and heating LNG which comes out of the LNG storage tank, and then delivering the LNG to the gas engine and comprises a pressurizing pump and a gasification system, and the gasification system comprises an LNG gasifier and an NG heater; the LNG storage tank is communicated with the pressurizing pump, the LNG gasifier, the NG heater and the gas engine in sequence through the pipes and the valves. The ship LNG fuel low pressure gas supply system can supply gas to the ship on which the gas engine is adopted. Pollution caused by an existing diesel engine to the environment is relieved.
Description
technical field [0001] The invention relates to the field of sea-going ship fuel supply, and features a low-pressure gas supply system for sea-going ship LNG fuel. Background technique [0002] The rapid development of the world economy has triggered a rapid increase in the world's demand for energy. With its clean, convenient and efficient characteristics, natural gas has become the most suitable high-quality new energy to replace coal and oil. With the rise of international oil prices and stricter emission requirements, the use of natural gas has become an inevitable trend in various fields. [0003] In the existing ships, diesel engines are mainly used. During the combustion of diesel, strong black smoke will be generated, which will pollute the environment. Since shipping often involves cross-border transportation, diesel engines in different countries have different advantages and disadvantages, which will cause different degrees of pollution to the environment, causi...
