Abstract

The invention relates to the field of ships, in particular to a liquefied natural gas supplying system. The liquefied natural gas supplying system comprises a storage tank and a gas heater, wherein the storage tank is used for storing liquefied natural gas and evaporation gas of the liquefied natural gas; a gas inlet of the gas heater is connected with a gas outlet of the storage tank; a gas outlet of the gas heater is used for being connected with a gas supplying opening of a ship engine; the gas heater is used for receiving the evaporation gas in the storage tank and heating the evaporationgas to a preset temperature, and then the heated evaporation gas is input into the ship engine through the gas supplying opening of the ship engine. The gas heater can heat the evaporation gas of theliquefied natural gas in the storage tank to the preset temperature, then the heated evaporation gas is input into the ship engine through the gas supplying opening of the ship engine, and the gas isprovided for the ship engine. The change amplitude of pressure in the storage tank can be lowered, and compared with an existing gas supply mode of gasifying the liquefied natural gas, the liquefied natural gas supplying system is advantageous in that the gas supply stability can be improved.

Description

technical field [0001] The invention relates to the field of ships, in particular to a liquefied natural gas supply system. Background technique [0002] Natural gas-powered ships use natural gas as fuel for energy supply, which has the advantages of energy saving and environmental protection. At present, natural gas-powered ships mostly use liquefied natural gas (LNG) as fuel storage form, so a liquefied natural gas supply system is required to supply gas to the ship's engines. The existing liquefied natural gas supply system generally includes components such as storage tanks, vaporizers and heaters. The storage tanks are used to store liquefied natural gas. The natural gas converted by the carburetor is heated to a suitable temperature. The existing gas supply system will cause large changes in the gas supply pressure when the pressure of the storage tank changes greatly, and has high requirements for gasification heat supply of liquefied natural gas, resulting in poor ...
