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
The present invention relates to oil fuel and preparation field thereof, be meant a kind of composite fuel oil that is applicable to boiler and preparation method thereof especially.
Background technology
Existing situation is that energy dilemma is on the rise and the consumption of petroleum amount constantly increases, and the cost and the price of high-grade fuel oil escalate, and people more hope to replace the high-quality fuel oil with reduced fuel oil.This makes various oil fuel all develop to the heaviness direction.
Domestic each province and city oil-firing boiler is in great demand, and because of there not being the boiler special oil, major part is made fuel with diesel oil, not only wastes national energy but also increased user's spending, also causes environmental pollution.The advantage of heavy oil, ultra viscous crude is that low price, calorific value are high.Its shortcoming is that viscosity is high, flash-point is low, be not easy to store, transport and use, and discharge amount of exhaust gas is big, and contaminate environment is serious.Because its these characteristics have only obtained application for a long time, and on general medium and small boiler, have been restricted on large-scale industrial combustion equipment.The employed burner of China's oil-firing boiler is mostly from imports such as Italy, Korea S, Germany, the U.S. at present, and they require very strict with to solve these difficult problems to the performance index of using oil product, be necessary to research and develop a kind of novel composite fuel oil.
Summary of the invention
The present invention proposes a kind of composite fuel oil and preparation method thereof, has solved the technical problem prior art medium viscosity is high, that flash-point is low, be not easy to store, transport, use, the heavy oil that discharge amount of exhaust gas is big and environmental pollution is serious, ultra viscous crude are used in boiler combustion.
Technical scheme of the present invention is achieved in that
A kind of composite fuel oil, its component comprises: heavy oil, solvent oil and additive;
Said heavy oil is process diluent, natural subsidence and filtration, the material behind the removal impurity;
Said additive comprises ignition dope (being the heavy oil multifunction additive), propellant (being catalyst for cracking), anticorrosive agent (being the oil corrosion suppressor factor) etc.
As optimized technical scheme, said solvent oil is carbon 9 or carbon 10.
As optimized technical scheme, the weight percent of component does in the said composite fuel oil, heavy oil 40-70%, solvent oil 10-30%, additive 10-30%.Preferred, heavy oil 60%, solvent oil 20%, additive 20%.
As optimized technical scheme, the weight ratio of said ignition dope, propellant, anticorrosive agent is 1-5: 1-5: 1-5.Preferred technical scheme, the weight ratio of said ignition dope, propellant, anticorrosive agent is 1: 1: 1.
Further, described composite fuel oil is applied in the boiler.
A kind of preparation method of composite fuel oil comprises:
(1) adding can be regulated the thinner of heavy oil denseness in heavy oil, and the mass percent of thinner in heavy oil is 1-2%;
(2) with the heavy oil process natural subsidence and the filtration of above-mentioned adding thinner, remove the impurity in the heavy oil;
(3) add solvent oil and additive in the heavy oil after step (2) is removed impurity, wherein additive is ignition dope, propellant, anticorrosive agent etc., and stirring promptly gets composite fuel oil.
Further, the heavy oil denseness that adds thinner in the said step (1) is reduced to, and under all temps condition, can guarantee the works better of burner.
The close flash point of the composite fuel oil of method for preparing is controlled in certain scope, makes its both National standard, and the security to guarantee to use can guarantee the safety of lighting a fire again.
The ignition dope among the present invention can make the required activation energy reduction of burning, thereby decline reaches the purpose that combustionvelocity is accelerated naturally.Contact with oxygen element on inner rather than surface when the oxygen element that the ignition dope molecule contains can make fuel combustion, further accelerate combustionvelocity.Propellant can reduce the fuel oil surface tension, makes fuel oil atomization functional, and the elaioleucite of injection directly reduces.The combustion particles diameter of jet atomization could guarantee stable burning accounting for more than 85% below 50 microns; Also to there be the particle dia more than 5% to keep perfect combustion 20 microns ability.The spray particle diameter of composite fuel oil of the present invention all reaches nano level, and the efficiency of combustion of fuel reaches the highest.Because compound fuel oil firing of the present invention is very complete, carbon in the fuel and protium all change into carbonic acid gas and water, so smokeless in the exhaust, dustless, fire cleaning.Anticorrosive agent can be retrieved the corrosion of burning line and nozzle, prevents the jet hole carbon distribution, makes the more stable work of nozzle, helps improving efficiency of combustion, the practical life of prolonged boiler parts, the routine maintenance of minimizing boiler.
Beneficial effect
(1) composite fuel oil of the present invention have energy-efficient, calorific value is high, raffinate is not stayed in environmental protection, safe, nontoxic, smokeless, no burn into, sanitation and hygiene, be prone to transportation, be prone to store and the low price characteristics; Simultaneously, do not receive season and climatic influences, reach the colleague's of country standard, the fuel-economizing amount on average can reach more than 15%; Compared with similar products, combustion efficacy is better, and price is more cheap, is the higher fuel oil of cost performance, is the preferred fuels of replacement liquid gasification and diesel oil; It is the main fuel that is widely used in office, enterprise, central air-conditioning, large-scale hotel, hotel commercial building, bathing, Saunas, catering trade;
(2) composite fuel oil of the present invention is applied in the burning of boiler the CO of flue gas, SO
2Content Deng composition obviously reduces, and boiler thermal output rises; The boiler internal foul improves significantly.
