Problems solved by technology

[0002] When the hull sails on the water, it will inevitably encounter wind and waves or extreme cold and hot weather. The fuel stored in the existing fuel tank is liquid. During the process of outputting fuel, it is transported to the vaporizer through a single pipeline. Then the gasified gas is delivered to the external combustion equipment. In this process, the liquid fuel in the pipeline has been partially gasified during delivery, which makes unnecessary gasification of additional energy consumption. The fuel reserve on the hull itself Therefore, the existing fuel gas supply process needs to be optimized

Abstract

The invention provides a gas supply process for a marine fuel tank, which enables the energy consumed by fuel conveying to be low, ensures the energy conservation of fuel gas supply, and ensures the efficient utilization of energy. The marine fuel tank comprises a double-layer tank body, the double-layer tank body specifically comprises an inner tank and an outer tank, LNG is stored in the inner tank, and the marine fuel tank is characterized in that a fuel outlet in the bottom of the inner tank is connected to an inlet of an immersed pump outside the double-layer tank body through a first pipeline, and a liquid outlet of the immersed pump is connected to a medium inlet of an LNG gasifier; a gas outlet of the immersed pump flows back to a top backflow port of the inner tank through a second pipeline, a medium outlet of the LNG gasifier communicates with a medium inlet of a heater through a third pipeline, a medium outlet of the heater outputs gas fuel through a fourth pipeline, and a heating medium is introduced into a heating medium inlet of the heater. A heating medium outlet of the heater is communicated to a heating medium inlet of the LNG gasifier through a fifth pipeline, and a heating medium outlet of the LNG gasifier outputs a heated heating medium through a sixth pipeline.

Description

technical field [0001] The invention relates to the technical field of fuel tank gas supply, in particular to a marine fuel tank gas supply process. Background technique [0002] When the hull sails on the water, it will inevitably encounter wind and waves or extreme cold and hot weather. The fuel stored in the existing fuel tank is liquid. During the process of outputting fuel, it is transported to the vaporizer through a single pipeline. Then the gasified gas is delivered to the external combustion equipment. In this process, the liquid fuel in the pipeline has been partially gasified during delivery, which makes unnecessary gasification of additional energy consumption. The fuel reserve on the hull itself Therefore, the existing fuel gas supply process needs to be optimized. Contents of the invention [0003] In view of the above problems, the present invention provides a gas supply process for marine fuel tanks, which reduces energy consumption for fuel transportation...
