Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention are used to distinguish similar objects and not necessarily to describe specific sequence or sequence.

[0024] Such as figure 1 As shown, the ship liquefied ammonia supply system provided by the embodiment of the present invention can be used in ships with two-stroke ammonia fuel engines. The high pressure supply system supplies liquid ammonia to the ammonia fuel engine 38 of the ship, the supply pressure is about 80 bar, and the supply temperature is about 45°C. Ammonia cracking hydrogen generation power generation system cracks and purifies ammo...

Abstract

The invention provides a ship liquid ammonia supply system. The ship liquid ammonia supply system comprises a liquid ammonia storage tank, a liquid ammonia supply pump, a low-pressure buffer tank, a high-pressure pump, a liquid ammonia heat exchanger, a high-pressure buffer tank, a first fuel valve group, an ammonia gas heat exchanger, an ammonia gas buffer tank, an ammonia cracking device, a hydrogen purification device, a hydrogen fuel cell, a ship direct-current power grid, an ammonia fuel engine, a waste gas heat exchanger and a circulating pump. According to the ship liquid ammonia supply system, through reasonable design, liquid ammonia supply of an ammonia fuel engine can be met, electric energy can be supplied to ship electric equipment, meanwhile, zero carbon emission can be achieved, and ship operation is more environmentally friendly. The invention further provides an ammonia fuel powered ship.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship liquid ammonia supply system and an ammonia fuel powered ship. Background technique [0002] In recent decades, the problem of global warming has become more and more serious, and the emission of greenhouse gases is an important cause of global warming and climate change. Among various greenhouse gases, CO 2 have the greatest impact on climate change. To control CO 2 Various international organizations have successively promulgated a series of laws and regulations, such as the "Paris Agreement" passed at the Paris Climate Change Conference in 2015, calling on all walks of life to take actions to reduce CO 2 emissions. [0003] In order to achieve the above emission reduction goals, the shipping industry has also introduced a series of emission reduction policies. The IMO MEPC72 meeting adopted the "International Maritime Organization's Strategy for Reducing Greenhouse Ga...
