Description

Boiler fuel oil

Technical Field

The invention belongs to the technical field of fuel oil, and particularly relates to boiler fuel oil.

Background

The fuel oil boilers in various domestic provinces and cities are in great demand, and because no special oil for boilers exists, most of the fuel oil is diesel oil, so that not only is the national energy wasted, but also the user expenditure is increased, and the environmental pollution is also caused; . With the increasing energy crisis, the increasing oil consumption and the increasing environmental awareness of people, the development of energy-saving and environment-friendly fuel oil as boiler fuel oil instead of diesel oil is urgent, and with the rapid development of the petrochemical industry in China, the yield of aromatic oil as a byproduct is greatly increased in each oil refinery, but most of aromatic oil is still used as fuel oil and mixed into vacuum residue oil, and is not effectively utilized.

Disclosure of Invention

The technical problem solved by the invention is as follows: the boiler fuel is prepared by taking methanol and aromatic oil as main components and adding a proper amount of higher alcohol and ferrocene, and the boiler fuel oil which is low in price, high in calorific value, stable in calorific value, energy-saving and environment-friendly is obtained and can be used for replacing diesel oil as the boiler fuel oil.

The invention provides boiler fuel oil which is prepared from the following raw materials in percentage by mass: 35-55% of methanol, 20-40% of aromatic oil, 12-26% of higher alcohol and 0.2-2% of ferrocene.

The aromatic hydrocarbon oil has sufficient resources, low market price and high heat value, and can be used as the components of boiler fuel oil, but the aromatic hydrocarbon oil generally has the problems of too large moisture and uneven viscosity, thereby influencing the combustion performance and bringing many disadvantages to the practical application of the aromatic hydrocarbon oil. The methanol oxygen-enriched fuel is completely combusted, the tail gas emission can be reduced, the fuel loss and the cost are reduced, and the intermiscibility of the methanol and the aromatic oil can be obviously improved by adding the high-carbon alcohol and the ferrocene. The boiler fuel oil uses methanol and aromatic oil as main components, and is improved by adding a proper amount of higher alcohol and ferrocene, so that the boiler fuel oil has the characteristics of good intermiscibility, high combustion heat value, capability of releasing fuel energy to the maximum extent, energy conservation and environmental protection.

On the basis of the scheme, the following improvements can be made:

further, the aromatic oil is a byproduct of an oil refinery, the water content of the aromatic oil is 4% -10%, and the percentage of aromatic carbon number in the aromatic oil to the total carbon number is 35% -45%.

According to the boiler fuel, the aromatic oil is derived from a byproduct of an oil refinery or a coal product, the cost of the fuel oil can be reduced by using the aromatic oil as the boiler fuel oil, and the methanol, the higher alcohols and the ferrocene are added to fully mix all components in the aromatic oil and a small amount of water in the aromatic oil, so that the boiler fuel oil has good atomization performance and high combustion efficiency, is stable for a long time, and is not easy to layer in the storage and transportation processes.

Furthermore, the composite material comprises, by mass, 40-50% of methanol, 25-35% of aromatic oil, 15-20% of higher alcohols and 0.5-1.5% of ferrocene.

The physical and chemical properties of the product are improved through reasonable blending, and partial key indexes (such as heat value, carbon residue, ash and the like) of the fuel can reach or even exceed the indexes of diesel oil.

Further, the composite material comprises, by mass, 50% of methanol, 19% of higher alcohol, 30% of aromatic oil and 1% of ferrocene.

In the proportion, the combustion heat value is high and the combustion is thorough, and the aromatic oil and the methanol can release the combustion energy to the maximum extent.

Further, the higher alcohol is carbon 16 to carbon 20.

Under the condition, the methanol and the aromatic oil have good intermiscibility.

Further, the methanol is industrial grade methanol.

Therefore, the methanol is low in price, and the fuel cost can be reduced.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
