Abstract

The ship with gas re-vaporization system of the present invention, which is characterized in that including:Hull;Vaporizer, is set to the top of the hull, and the vaporizer makes liquid gas vaporization to supply to needing to locate;And heat source feedway, it is set to the inside of the hull, the heat source feedway supplies heat source to the vaporizer.

Description

The ship of system is re-vaporized with gas
Technical field
The present invention relates to a kind of ships re-vaporizing system with gas.
Background technology
Generally, it is known that LNG is clean fuel, and reserves are also abundanter than oil, as mining and transhipment technology are flourishing, The usage amount of LNG also sharply increases.Such LNG will usually drop to temperature under 1 atmospheric pressure as the methane of principal component- 162 DEG C hereinafter, to be taken care of with liquid condition, the volume of liquefied methane is the methane volumetric of the gaseous state of standard state 1/600th or so, proportion 0.42 is the 1/1 of specific gravity of crude.
After LNG is liquefied and carried because of its carrying easiness, used being vaporized using place.But because certainly Right disaster and Terrorism risks worry that LNG vaporization equipment is arranged on land.
