The fuel combustion improver provided by the invention mixes one or more metal compounds of an aluminum-containing compound, an iron-containing compound and a magnesium-containing compound with a solvent, and simultaneously forms a colloidal dispersion with positively charged colloidal particles at least partially in the solvent through hydrolysis or dispersion and other modes, wherein the positively charged colloidal particles have strong adsorbability, relatively few positively charged colloidal particles can be uniformly attached to the fuel in the contact process of the positively charged colloidal particles and the fuel and oxygen can effectively reduce the energy required by oxygen molecules to open double bonds of the oxygen molecules in the contact combustion process of the fuel and the oxygen, so that the combustion efficiency of the fuel is improved, the full combustion of the fuel is ensured, pollution products are reduced, and the calorific value is improved.

In some embodiments, the solvent is water.

Water is not mutually soluble with most of the existing fuels, and the effective separation of the fuel combustion improver and the fuel can be realized by adopting water as a solvent, so that the influence on the combustion performance of the fuel is avoided.

As a further improvement of the invention, the fuel combustion improver also comprises acid, and the pH value of the fuel combustion improver is 2-7.

The purpose of adding acid into the fuel combustion improver is to improve hydrogen ions, and colloid particles are easier to carry positive charges under an acidic condition, so that the attachment of the colloid particles to fuel is facilitated, and the combustion-supporting performance of the fuel is improved.

In some embodiments, the acid comprises one or more of citric acid, carbonic acid, hydrochloric acid, and acetic acid.

In some embodiments, the mass ratio of the solvent to the metal compound is 1000: 0.01 to 60.

In different embodiments, different materials can be used for the aluminum-containing compound.

In some embodiments, the aluminum-containing compound is an aluminum salt.

The aluminum salt is easy to hydrolyze in the water solvent, wherein different combination modes between the aluminum ion and the hydroxyl ion can generate a plurality of colloid particles with positive charges, and the hydrolysis of the aluminum salt can be promoted by adopting a mode of heating according to the solubility of the aluminum salt, so that the fuel combustion improver in the colloid form required by the invention is obtained.

Specifically, in one embodiment, the aluminum-containing compound is selected from aluminum sulfate, and the mass ratio of the solvent to the aluminum sulfate is 1000: 10 to 60.

In another embodiment, the aluminum-containing compound is selected from potassium aluminum sulfate, and the mass ratio of the solvent to the potassium aluminum sulfate is 1000: 30-60.

In some embodiments, the aluminum-containing compound is aluminum hydroxide, and the mass ratio of the solvent to the aluminum hydroxide is 1000: 0.01 to 30.

In some embodiments, the iron-containing compound is selected from iron sulfate, and the mass ratio of the solvent to the iron sulfate is 1000: 10 to 60.

Ferric sulfate can form ferric hydroxide colloid by titration in high temperature boiling water.

In some embodiments, the magnesium-containing compound comprises one or more of magnesium sulfate and magnesium oxide.

When the magnesium-containing compound is selected from magnesium sulfate, the mass ratio of the solvent to the magnesium sulfate is 1000: 10 to 60.

The magnesium sulfate hydrolyzes in water to form colloidal particles containing metallic magnesium.

When the magnesium-containing compound is selected from magnesium oxide, the mass ratio of the solvent to the magnesium oxide is 1000: 10 to 60.

When added into water, the magnesium oxide can react with the water to produce the colloidal particles of the magnesium hydroxide by controlling the reaction conditions.

The invention also provides the application of the fuel combustion improver in fuel combustion supporting.

In some embodiments, the fuel is selected from coal, and the process of applying comprises: the fuel combustion improver is infiltrated into the coal, and the coal is dried to be used for combustion.

Specifically, before the fuel combustion improver is infiltrated, the coal can be crushed into particles, the smaller the particle size of the coal is, the more favorable the infiltration of the fuel combustion improver is, and the crushing mode can be extrusion or grinding and the like.

The infiltration method of the fuel combustion improver can adopt a soaking method or a spraying method and the like, so that the positively charged colloidal particles in the fuel combustion improver can be attached to coal.

When the permeation of the fuel combustion improver is completed, the solvent needs to be removed, and the solvent can be removed by adopting various existing methods, such as vacuum removal, hot air removal, heating removal or natural airing, and the natural airing mode is preferably adopted from the viewpoint of reducing energy consumption.

It should be noted that the drying of coal does not require complete drying, and the normal combustion of coal can be ensured when the moisture content of coal reaches 11%.

The gasoline and diesel oil are not mutually soluble with the hydrosolvent of the fuel combustion improver, and the density of the gasoline and diesel oil is lower than that of the hydrosolvent, so that the gasoline or diesel oil can be introduced into the fuel combustion improver through a pipeline and can be automatically separated in layers after being fully contacted with the fuel combustion improver, and the colloid particles with positive charges in the fuel combustion improver have better adsorbability, so that the colloid particles can be taken out of the fuel combustion improver through the gasoline or diesel oil to participate in subsequent combustion reaction.

When the fuel is gas fuel such as natural gas, the action process is similar to that of gasoline and diesel oil, the natural gas is introduced into the fuel combustion improver, and the colloid particles with positive charges in the fuel combustion improver are carried out by the natural gas to participate in the subsequent combustion reaction.
