Description

Ammonia fuel supply system for marine diesel engine
Technical Field
The invention relates to a diesel engine, in particular to a diesel engine fuel supply device.
Background
Currently, the combustion of fossil fuels poses a number of environmental problems. In addition, the limited reserves of fossil resources also determine the need to find an alternative fuel. In marine engines, petroleum products are mainly used at present as fuels, which not only emit a large amount of greenhouse gases and harmful gases, but also have certain dangers in terms of fuel storage, such as flammability and explosiveness. In recent years, international maritime organizations have promulgated more strict regulations on energy conservation and emission reduction, and clean and green fuels gradually come into the visual field of people.
Many clean fuels, such as ethanol, dimethyl ether, biodiesel, and hydrogen, have been fully theoretically studied and experimentally verified in engines. The most loud green fuels at present are ammonia and hydrogen, and the complete combustion products of the ammonia and the hydrogen are harmless to the environment. However, hydrogen is flammable and explosive, difficult to store and transport, high in production cost and difficult to apply to engines. The ammonia gas is the largest chemical product all over the world, has an extremely mature production process and matched auxiliary facilities, and can quickly establish an ammonia station all over the world. In addition, ammonia has relatively good combustion characteristics, such as: high octane number, large volume energy density, moderate heat value. Therefore, the adoption of ammonia as a fuel is definitely feasible and has good prospects.
Heavy oil is mainly used in the current marine diesel engine, and a fuel supply system is also used for supplying the heavy oil. Although the present new type of ship employs a dual fuel supply system, the fuel burned in the engine cylinder is not a mixture of two fuels, but different fuels are used in different sailing areas. Such as the ability to provide light oil to the engine for combustion at an offshore port, such a dual fuel supply system cannot be used as an ammonia fuel supply system. In addition, the ammonia gas is directly sent to the engine in the traditional fuel supply pipeline, so that the ammonia gas is difficult to combust in the engine, and the leakage of the ammonia can cause serious safety problems.

1. the ammonia transmission pipeline comprises a double-layer pipeline consisting of an inner pipeline and an outer pipeline, the inner pipeline is arranged inside the outer pipeline, the inner pipeline is a transmission pipeline for ammonia, the outer pipeline is a shielding pipe, an ammonia leakage protection device is arranged on the outer pipeline, the ammonia leakage protection device comprises an ammonia leakage probe and an ammonia leakage indicator, the end part of the ammonia leakage probe is positioned in the outer pipeline, and the ammonia leakage probe is connected with the ammonia leakage indicator.
2. An ammonia leakage protection device is arranged at the downstream of each section of ammonia transmission pipeline, and valves are arranged at the two ends of each section of ammonia transmission pipeline.
3. The ammonia is in ammonia transmission line transportation process, and when the pipeline took place to be damaged in the interior, the ammonia leaked to outer pipeline from interior pipeline, and the ammonia that leaks will drive downstream at the air that flows, and the ammonia leaks the concentration signal that the probe detected the ammonia and sends ammonia leakage indicator to, judges the size of leaking out the volume, if need change the pipeline, the valve at this section ammonia transmission line both ends is closed the back, changes new pipeline.
The invention has the advantages that: in marine diesel engines, the use of ammonia fuel can reduce carbon emissions and pollutant emissions to some extent. The heat value of the ammonia fuel is high, the ammonia fuel is easy to liquefy and store, the energy density is high, and the storage space of fuel oil on a ship is reduced. In addition, the nature of the ammonia fuel determines that the ammonia is not easy to explode, and the safety of the ship is guaranteed. If ammonia fuel leaks, the ammonia fuel can be detected when the concentration of the ammonia fuel in the air reaches 5.3ppm due to the strong irritation of the ammonia fuel. Finally, ammonia, as the largest chemical product worldwide, has mature supporting facilities and can be rapidly applied to energy supply of ships.
