Embodiment Construction

[0038] Hereinafter, one embodiment of a natural gas fuel evaporator, a natural gas fuel supply device, and a method of supplying natural gas fuel to a ship or an engine according to the present invention will be described with reference to the drawings.

[0039] Such as figure 1 As shown, a fuel gas supply system (natural gas fuel supply device) 10 is mounted on a ship in order to drive, for example, a turbine (engine, fuel supply object) in the ship, and LNG (natural gas fuel (liquid gas fuel) )) is gasified and supplied to the turbine or engine at the supply destination.

[0040]This fuel gas supply system 10 includes: a fuel tank 11 storing LNG; and an evaporator (natural gas fuel evaporator) 20 for evaporating the LNG liquid supplied from the fuel tank 11 .

[0041] The fuel tank 11 may be a fuel tank for storing LNG as fuel, or may be a cargo oil tank for storing LNG as a load in an LNG carrier. In this fuel tank 11, LNG is stored, for example, at -160°C.

Abstract

The purpose of the present invention is to reduce the cost of fuel gasification equipment for LNG and other liquefied gas. The methane component of LNG liquid inside a holding tank (21) is evaporated, turned into LNG gas, and discharged from the holding tank (21), by: supplying LNG liquid that has been heated by a heating unit (22), putting LNG liquid inside the holding tank (21) into a saturated state, opening a throttle valve (33); and reducing the pressure inside the holding tank (21). In addition, it is preferable that the accumulation of heavy components inside the holding tank is avoided by supplying some of the LNG liquid inside the holding tank (21) to a desuperheater (43), via a branch pipe (50).

Description

technical field [0001] The present invention relates to a natural gas fuel evaporator for gasifying natural gas fuel used as engine fuel, a natural gas fuel supply device, and a method for supplying natural gas fuel to ships and engines. Background technique [0002] In equipment that burns liquefied natural gas (LNG), liquefied petroleum gas (LPG), etc. as fuel in boilers, engines, etc. It is compressed in the compressor and sent to the engine. [0003] When using the natural gas fuel stored in the gas tank by gasification, there is a method of using boil-off gas that vaporizes the natural gas fuel in the gas tank by inputting heat from the outside to the gas tank, but this The method cannot supply the gas quantity requested by the engine side. Therefore, if figure 2 As shown, the liquid phase of the natural gas fuel (LNG) in the gas storage tank is drawn out and heated in the evaporator (gasifier) ​​2 to evaporate it (for example, refer to Patent Document 1.). [0004]...
