Problems solved by technology

But at present, there are many problems in this method in practice: because water and oil are insoluble, although there is an emulsified state formed by an emulsifier, it is still unstable, so the combustion is also unstable.
Some metal salts of naphthenic acid such as calcium, cobalt, iron, manganese, zinc and various inorganic salts are added to some heavy oil additives. Although these metal salts can catalyze oxidation and support combustion, they are easy to form metal oxides to pollute the cylinder and affect the heat transfer. Detrimental effect and also wear on the piston as it moves up and down, shortening the life of the engine

Abstract

The invention discloses a new environmentally-friendly heavy oil additive and a preparation method and use method thereof. The additive comprises the following components in parts by weight: 10-30 parts of nonionic surfactant, 15-60 parts of combustion improver, 10-30 parts of quality stabilizer, 10-55 parts of purification dispersant, 1-8 parts of corrosion inhibitor and 20-50 parts of water. After the materials are combined according to percentages, the materials can be used with heavy oil mixed with water and the fuel properties of heavy oil are improved. The environmentally-friendly heavy oil additive has the following advantages: the combustion performance of heavy oil can be effectively improved, the liquidity of heavy oil can be increased, the heavy oil fuel oil with the additive has stable performance, long storage time, good atomizing effect, no pollution and high oil-saving efficiency, is easy in ignition and can not coke, the fuel oil does not corrode the equipment, has high combustion value and simple process, is difficult in black smoke generation, is convenient in use and can combust completely, and the equipment loss is reduced furthest.

Description

technical field [0001] The invention relates to a heavy oil additive, in particular to a heavy oil additive and a preparation and use method thereof, belonging to the field of heavy oil additives. Background technique [0002] With the rising price of fuel oil, in the use of marine fuel, due to the large price gap between diesel and heavy fuel oil, the price of heavy oil is relatively lower than that of light oil. In order to control the transportation cost of existing ships, the main engine However, these low-quality heavy oils contain a large number of substances that are not easy to decompose, including: hydrocarbons, colloidal asphaltenes, metal ash, water, and harmful elements such as nitrogen and sulfur, and their viscosity, High density, high ignition point, and due to the influence of the inherent characteristics of heavy oil and the interference of various factors, in actual use, there are problems such as incomplete combustion, coking and carbon deposits, low therm...
