Description
Technical field
The present invention relates to fuel area, and in particular to the alcohol-based fuel of not smoked eye during use.
Background technology
Alcohol-based fuel is a kind of based on methanol, is mixed with the liquid fuel of the polyalcohols such as ethanol, propyl alcohol and alkane, again
It is named as " methyl fuel ".It is also a kind of biomass energy, is various countries as nuclear energy, solar energy, wind power energy, hydraulic energy
The environment protection clean energy that government widelys popularize at present.The calorific value of alcohol-based fuel typically between 2011-2610MJ/kg, be diesel oil,
60% or so of the exotic fuels calorific value such as liquefied gas, belongs to low heat value liquid fuel, and alcohol-based fuel can be with water in any proportion
It is mutually dissolved, but does not form azeotropic mixture with water, the calorific value of aqueous fuel will be lower.
The research of present alcohol-based fuel is a lot, such as Chinese patent CN102625825A, discloses a kind of methanol-based liquid combustion
The production method of material, methods described include：By the methanol of 55-80% by volume, by volume 23-50% water and by volume
The accelerator for counting 2-5% is mixed to form premix, the height for then making premix be subjected in mechanical high frequency ultrasound reactor
Frequency sonic oscillation, is added after that the catalyst of 3%-5% by volume, then makes premix by pressure filter,
It is finally set to seal at least 48 hours, so as to produce liquid fuel.The ratio of formula reclaimed water can at most account for 50%, it is possible to understand that
For " water becomes oil ".And for example Chinese patent CN103184081A, a kind of alcohol-group fuel oil is disclosed, by the component group of following parts by weight
Into：Methanol 70-75 parts, dimethylbenzene 4-6 parts, No. 200 solvent naphtha 4-6 parts, paraffin oil 4-6 parts, glycerine 4-6 parts, water 5-10 parts.But
It is that there is also deficiency, adds water in order to reduce cost so that methanol content makes fuel value very below 75% in fuel

It is that moisture is mixed into fuel, two aspects is shown to metal erosion：First, moisture can directly cause the chemical nuclear power of metal
Learn corrosion；Second, as some sulfur-bearing and sour corrosion materials in fuel be dissolved in water when, then accelerate corrosion of metal process.
Harm of the free water to metal in fuel is very big, and it can corrode various steel components.As steel oil tank, oil drum, pipeline, valve and
Other parts.The micro-moisture being dissolved in fuel can only cause low content steel corrosion.Moisture has stronger to low-alloy steel
Corrosiveness, also corrode the non-ferrous metal such as copper and zinc, corrosion is not produced to bronze.Chinese patent CN103923709A, improving

In the prior art, many alcohol-based fuel producers declare to the addition of stabilizer, emulsifying agent in fuel, calorific value after burning
Height, discharge amount of exhaust gas are extremely low.Although some manufacturing enterprises boast fantastically the emulsifying agent added, actually various
The so-called stabilizer being exclusively formulated, emulsifying agent are often the mixture of the chemicals such as flavor enhancement, coloring agent, metal ion, and one
As be all 6-9 kinds industrial chemicals dissolving after mixing liquid, the relation with environmental emission reduction in combustion process is not too big.Part
Producer declares to have it is possible to additionally incorporate additive in alcohol-based fuel to improve calorific value, can greatly improve the calorific value of fuel.
But in fact, unless disregard into local other fuel for adding high heating value, otherwise, only add based on all kinds of industrial chemicals
Additive alcohol-based fuel low heat value can only be made to be changed in a small range, the alcohol-based fuel low heat value after adjustment is difficult often
Break through 27MJ/kg.In actual use, rear kitchen personnel not only have carbon distribution after generally reflecting fuel combustion, and flue gas is smoked
Eye, it is necessary to force air draft ability normal work with blower fan, problem is still present.
