Embodiment Construction

[0036] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0037] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0038] The invention provides a fuel supply system, which provides liquefied natural gas for a natural gas-powered ship.

[0039] A natural gas-powered ship mainly includes a hull and an engine. The fuel supply system provides natural liquefied natural gas for the engine, which in turn provides power for the movement of the hull. Specifica...

Abstract

The invention provides a fuel supply system and a fuel supply method. The fuel supply system comprises a control device, a conveying pump and multiple feeding devices arranged on the upstream of the conveying pump in parallel. The multiple feeding devices sequentially communicate with the conveying pump and sequentially provide liquefied natural gas outwards. Each feeding device comprises a storage tank, liquid level detection equipment, a feeding branch and temperature detection equipment. The liquid level detection equipment is arranged corresponding to the storage tanks and used for detecting the liquid level of the liquefied natural gas. The feeding branches are connected with the storage tanks and the conveying pump. The temperature detection equipment is arranged on the feeding branches. The control device is electrically connected with the liquid level detection equipment and the temperature detection equipment of all the feeding devices. When the real-time liquid level value detected by the liquid level detection equipment in the current feeding device reaches a first liquid level preset value, the control device controls the feeding device to be used for feeding to conductprecooling. When the temperature of the feeding branch of the feeding device to be used for feeding is precooled to the work temperature, the control device controls the feeding device to be used forfeeding to communicate with the conveying pump.

Description

technical field [0001] The invention relates to the technical field of natural gas fuel supply, in particular to a fuel supply system and a fuel supply method. Background technique [0002] As the world pays more and more attention to environmental issues, natural gas is being used more and more widely as a new clean energy. The demand for natural gas-powered ships powered by natural gas is also increasing. Marine fuel tanks are divided into two types: fixed and movable. At present, most natural gas-powered ships use fixed fuel tanks. Due to the limited number and uneven distribution of natural gas water refueling stations in use, the large number of natural gas-powered ships Scale application is severely restricted. [0003] After the portable fuel tank is filled at the land liquefaction station, it is then fixed on the ship by hoisting or roll-on. Its "filling" operation can be completed in most existing ports and wharves without being restricted by the water filling sta...
