Problems solved by technology

But at present, the application of methanol / fuel oil dual fuel system in large ocean-going ships is still a blank field, and the conventional fuel oil supply system and LNG gas supply system are not suitable for methanol fuel, that is, the supply of methanol / fuel oil fuel must be provided with a dedicated fuel supply system

Abstract

The invention provides a methanol and fuel oil dual-fuel supply system comprising a methanol fuel temporary storage container, a methanol fuel supply unit, a methanol fuel valve group and an ignition fuel oil supply unit, and the methanol fuel temporary storage container is used for containing methanol fuel. The methanol fuel temporary storage container, the methanol fuel supply unit and the methanol fuel valve group communicate in sequence, the methanol fuel valve group is used for conveying the methanol fuel to an engine, and the ignition fuel supply unit is used for supplying ignition fuel into the engine. The methanol and fuel oil dual-fuel supply system has the advantages of being reasonable in structure and safe and reliable to use.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a methanol fuel dual fuel supply system. Background technique [0002] With the entry into force of the global "sulfur limit order" and the increasingly stringent IMO carbon emissions, the replacement of marine fuel is imminent. At present, the fuel of large ocean-going ships mainly includes fossil fuels such as fuel oil and LNG; therefore, the ship fuel supply scheme is usually designed according to these two fuels, that is, it is mainly realized by the ship fuel oil supply unit and the LNG gas supply system. Dual fuel supply for marine power units. For LNG carriers, part of the LNG will inevitably be evaporated during the transportation process, and using this evaporated LNG as the fuel of the ship can effectively reduce the operating cost of the ship and reduce the loss rate of LNG. For ordinary dual-fuel ships, the cost of retrofitting and using LNG fuel is relati...
