Embodiment 1

[0026] A compound fuel oil, its components include: heavy oil, carbon 9 and additives; heavy oil is the substance after diluting with diluent, natural sedimentation and filtration to remove impurities; wherein the filtration is precision filtration; the additive is heavy oil multifunctional additive, cracking Catalyst and oil corrosion inhibitor. The weight percent of components in the compound fuel oil is 60% of heavy oil, 20% of solvent oil and 20% of additives. The weight ratio of the combustion aid, the atomizing agent and the anticorrosion agent is 1:1:1. The oxygen element contained in the oxidizer molecule can make the fuel burn in contact with the oxygen element instead of the surface, further accelerating the burning speed. The atomizing agent can reduce the surface tension of the fuel oil, so that the fuel oil atomization performance is good, and the sprayed oil particle size is reduced. The diameter of the spray particles of the composite fuel oil reaches the nano...

Embodiment 2

[0028] A compound fuel oil, its components include: heavy oil, carbon 9 and additives; heavy oil is the substance after diluting with diluent, natural sedimentation and filtration to remove impurities; wherein the filtration is precision filtration; the additive is heavy oil multifunctional additive, cracking Catalyst and oil corrosion inhibitor. The weight percent of components in the compound fuel oil is 40% of heavy oil, 30% of solvent oil and 30% of additives. The weight ratio of the combustion aid, the atomizing agent and the anticorrosion agent is 1:5:1.

Embodiment 3

[0030] A compound fuel oil, its components include: heavy oil, carbon 10 and additives; heavy oil is a substance that has been diluted with a diluent, naturally settled and filtered to remove impurities; the filtration is precision filtration; the additive is a heavy oil multifunctional additive, cracking Catalyst and oil corrosion inhibitor. The weight percent of components in the compound fuel oil is 70% of heavy oil, 10% of solvent oil and 20% of additives. The weight ratio of the combustion aid, the atomizing agent and the anticorrosion agent is 2:5:2.

[0031] When the composite fuel oil of the present invention is applied to the combustion of boilers, CO and SO in flue gas 2 The content of other components is significantly reduced, and the thermal efficiency of the boiler is increased. The fouling inside the boiler has been significantly improved.

Abstract

The invention provides composite fuel oil and a preparation method thereof. The composite fuel oil comprises the following components of heavy oil, solvent oil and an additive, wherein the heavy oil is a substance diluted by a diluent, naturally settled and filtered; and the additive comprises a combustion-supporting agent, an atomizing agent and an anticorrosive agent. The preparation method comprises the following steps of: adding the diluent into the heavy oil; naturally settling and filtering the heavy oil added with the diluent, and removing impurities from the heavy oil; adding the solvent oil and the additive into the heavy oil after the impurities are removed, and stirring to obtain the composite fuel oil. The composite fuel oil provided by the invention has the characteristics of high efficiency, energy conservation, environmental friendliness, safety, no toxicity, no smoke or corrosion, no remained liquid, cleanness, sanitation, easy transportation, easy storage and low price; the oil saving amount can reach more than 15% averately; the composite fuel oil is the preferred fuel for replacing liquefied gas and diesel; when the composite fuel oil is applied in burning of a boiler, the content of components such as CO and SO2 of the flue gas is obviously reduced, and the heat efficiency of the boiler is increased; and the scaling condition in the boiler is obviously improved.

Description

technical field [0001] The invention relates to the field of fuel oil, in particular to a composite fuel oil suitable for boilers. Background technique [0002] The current situation is that the energy crisis is getting worse and the oil consumption is increasing continuously, the cost and price of high-quality fuel oil are rising rapidly, and people hope to replace high-quality fuel oil with heavy fuel oil. This makes all kinds of fuel oils are developing in the direction of heavy quality. [0003] There is a great demand for oil-fired boilers in various provinces and cities in China. Because there is no special oil for boilers, most of them use diesel oil as fuel, which not only wastes national energy, but also increases user expenses and causes environmental pollution. The advantages of heavy oil and super heavy oil are cheap price and high calorific value. Its disadvantages are high viscosity, low flash point, inconvenient storage, transportation and use, and large exh...
