Embodiment 1

[0029] Weigh the raw materials of the following weight percentages:

[0030] 10% n-decyl alcohol 10% n-octanol 5% petroleum ether 30% n-butanol

[0031] Naphthenic acid 8% Oleic acid 25% Glycerin 2% Ammonia 1%

[0032] Span 80 8% Sodium Dodecyl Benzene Sulfonate 1%.

[0033] Its preparation method is: pour n-decyl alcohol, n-octanol, petroleum ether, and n-butanol in the above weight percentages into a reaction kettle with a rotation speed of 400-400 rpm and stir, and then stir and fuse under normal temperature and fireproof and explosion-proof conditions. , then add the naphthenic acid, oleic acid, and glycerin of the above proportioning ratio successively and stir, then add the naphthenic acid, oleic acid, and glycerin for stirring, then add the sodium dodecylbenzenesulfonate, ammonia water, and The disc 80 is made by adding it into the reactor and stirring for 20 minutes. It is packed in barrels and sealed, and each barrel is filled with 180kg.

Abstract

The invention discloses a water-oil-coal emulsified fuel which is prepared by the following raw materials according to the parts by weight: 10-40 parts of coal powder and 30 parts of emulsified oil. The preparation method comprises the following steps: (1) first preparing the emulsified oil: weighting 20.4-26.4 parts of water, 3-9 parts of diesel oil and 0.6 part of emulsifier, then mixing the three components, stirring the mixture with a stirrer to emulsive state and obtaining emulsified diesel oil; (2) adding coal powder in prepared emulsified oil and stirring the mixture evenly which contains 30 parts of emulsified oil and 30 parts of coal powder. The beneficial effects of the invention are as follows: the emulsified fuel can increase the contact area of coal powder used in combustion reaction with the help of the combustion explosion of water and oil molecules, ensure the coal powder to burn more completely and increase the combustion efficiency; meanwhile, the emulsified fuel can not generate black smoke when burning so as to not only reduce the pollutant discharge but also solve the problems that water-coal-slurry is easy to demix, secondary pollution is easy to cause and the like in China.

Description

technical field [0001] The invention relates to a fuel, in particular to a water-oil-coal emulsified fuel and a preparation method thereof. Background technique [0002] my country is a big country in energy production and consumption. Coal is the main source of energy for our country. However, the burning of coal causes serious pollution. The black smoke or "smoke" produced by coal will reduce the amount of solar radiation reaching the ground, and the emissions from power stations into the atmosphere A large number of smoke particles made the air very cloudy and blocked the sunlight. According to relevant statistics, on days when the smog persists in large industrial cities, the amount of direct sunlight hitting the ground is nearly 40% less than that on days without smog. Poor growth and development due to lack of sunlight. [0003] In my country's natural resources, the basic characteristics are rich in coal, poor in oil, and low in gas, which determines the important po...
