Description
The present invention relates to a pulverized coal and a method for producing the pulverized coal. More particularly, the present invention relates to a method for producing pulverized coal, such as coal, (Fossil fuels), it can be used as heating fuel for heating boilers or as cooking fuel to cook meat or to cook various kinds of food, to prevent natural damage, and to prevent air pollution by exhaust smoke And to reduce the reprocessing cost of ash discharged after the combustion, and a manufacturing method thereof.
In general, various types of furnaces have been proposed and marketed in order to warm the indoor space in a relatively short time when the outside temperature is low as in winter.
In addition, as the life becomes more abundant compared to the past, the intake of meat (meat) increases, and the meat is cooked instead of the conventional hot water food.
Such a stove has been developed and used variously according to the type of fuel used. Recently, due to the rise of oil price and the increase of electric charge, the conventional stove which uses fuel and electric energy as fuel instead of the stove, Of coal stoves are used in many cases, and when cooking meat by baking, coal is often used as fuel.
On the other hand, as shown in Figure 1, coal (coal) is a black or brown flammable mineral which is produced by decomposing the food material under the heat and pressure of the ground while it is buried in the ground for a long time. Or as a raw material for the chemical industry.
Figure 1. Image of coal
However, since most of the above coal exists in a state buried underground, there is a problem that it is inevitably seriously damaged in nature in order to be mined, and since it is mined in a solid form, handling and transportation are very difficult, Since smoke, dust, oxides of sulfur and oxides of nitrogen are contained in a large amount in exhaust gas, the air pollution inevitably causes pollution of the environment.
In addition, coal burns a large amount of ash after burning. The coal ash is not easily recycled because it contains carcinogens, heavy metals, and radioactive materials. When buried in rice fields or fields, it seriously pollutes the soil. there is a problem.
Accordingly, the inventor of the present invention has conducted researches for a long time, and as a result, the inventors of the present invention have found that, as a result of researches for a long time, the grass which is naturally grown in the mountains is harmless to the human body and does not pollute the atmosphere during combustion, And developed a new grass (grass) that can be used as a soil modifier without modification.
DISCLOSURE OF THE INVENTION The present invention has been made to solve such conventional problems, and it is an object of the present invention to provide a method and apparatus for collecting various kinds of grass native to the mountains and the like, drying and cutting them, The present invention provides a new pulverized coal which can be used as a heating fuel for heating a boiler or as a cooking fuel for cooking meat or cooking various kinds of food.
Another object of the present invention is to provide a new method for preventing natural damage and reducing the air pollution caused by exhaust smoke and reducing the cost of ash processing after combustion It is to provide pulverized coal.
It is still another object of the present invention to provide a method for producing a new pulverized coal having the above functions.
In order to achieve the above object, a method for producing pulverized coal according to the present invention comprises: a pulping step of collecting a grass native to a mountain or a field; A grass drying step of naturally drying or hot-air drying the grass collected so that the moisture content of the collected grass is 3 to 7%; A grass cutting step of cutting the grass dried in the grass drying step to a length of 0.1 to 2.0 cm; 2.0-4.0 wt.% Of anthracite charcoal, 1.0-3.0 wt.% Of loess powder, 2.0-4.0 wt.% Of oil sludge, 10.0 wt. And then mixing the materials uniformly; A carbon forming step of compressing the mixed material at a pressure of 0.5 to 1.5 ton / cm < 2 > for 5 to 20 minutes while the mixed material is placed in a mold; And a step of discharging the molded pulp from the mold and naturally drying the pulp for 1 to 2 days at a place where moisture is not penetrated.
The pulverized coal (grass) according to the present invention has the characteristics produced through the above-mentioned production process.
According to the present invention, various types of grass native to the mountains and fields are collected, dried and cut, and then full seed, food carbonized charcoal powder, trace amount of anthracite coal, loess powder and oil sludge are added and mixed, So that it can be used as cooking fuel for cooking a heating fuel or meat for heating a boiler or cooking various foods in place of a conventional fossil fuel such as coal.
In addition, since the pulverized coal produced by the present invention is made purely from grasses collected from mountains and fields, it is prevented from natural damage, and fumes discharged from the processes used as fuels include fossil fuels such as coal (Ash), which is generated after burning, can be used as a soil reforming agent because it contains almost no harmful components such as dust, sulfur oxides and nitrogen oxides generated when the combustion is carried out, As a result, the cost of reprocessing of ash is greatly reduced, which is economically advantageous.
In addition, when the pulverized coal according to the present invention is burned to cook the meat, the smell of the grass is included in the smoke generated when the pulverized coal is burned to improve the flavor feeling of the grilled meat, There is an advantage.
Hereinafter, preferred embodiments of the present invention will be described in detail.
The pulverized coal according to the present invention can be used as cooking fuel for heating a boiler or cooking fuel for cooking various foods or cooking meat for heating boilers instead of conventional fossil fuels such as coal.
To this end, the pulverized coal according to the present invention is dried and pulp-cut to a length of 0.1 to 2.0 cm, wherein the pulp slurry is pulverized in a ratio of 75.0 to 85.0% by weight, 8.0 to 10.0% by weight of full seed, 2.0-4.0% by weight of carbonized food charcoal, 1.0 to 3.0 wt.% Of loess powder, 2.0 to 4.0 wt.% Of oil sludge, and then mixed thoroughly for 5 to 20 minutes at a pressure of 0.5 to 1.5 ton / cm 2 in a mold.
The pulp, which is the main material of the pulverized coal according to the present invention, is used in all kinds of grass native to the mountains. When the pulverized grass is added in an amount of less than 75.0% by weight, it takes time to ignite, When added, the ignition time is shortened and the duration of the fire power is shortened.
The charcoal powder used in the present invention acts to maintain the duration of firepower after ignition, and is a food charcoal powder obtained by burning food, wherein the food charcoal powder is less than 2.0 wt% The duration of thermal power is shortened, and if the addition amount of the food charcoal powder exceeds 4.0% by weight, it is economically disadvantageous.
Meanwhile, the anthracite added to the present invention is intended to ensure that the materials constituting the pulverized coal are evenly mixed with each other and the duration of the thermal power is secured. When the anthracite coal is added in an amount of less than 2.0 wt%, the duration of the thermal power is shortened, If the addition amount exceeds 4.0% by weight, it is economically disadvantageous.
The above-mentioned loess powder improves the soil strength when the ash discharged from the soil is sprayed to the soil, adsorbs heavy metals and harmful substances contained in the soil, and modifies the soil to stabilize the root of the crops cultivated in the soil When the amount of the loess powder is less than 1.0% by weight, the effect of the soil modification is deteriorated. If the amount of the loess powder is more than 3.0% by weight, it is economically disadvantageous.
When the oil sludge is added in an amount of less than 2.0% by weight, the formed pulverized coal is easily crumbled, and the oil fractions If the added amount of the sludge exceeds 4.0 wt%, the moldability becomes rather poor due to viscosity.
In order to produce the pulverized coal according to the present invention, the grass which is naturally grown in the mountains or the fields is first collected (the step of collecting the grass), and the collected grass is naturally dried using sunlight and wind, And dried to a moisture content of 3 to 7% (full drying step).
The grass dried in the grass drying step is cut to a length of 0.1 to 2.0 cm (pull cutting step), and the seeds are pulverized in a proportion of 75.0 to 85.0% by weight of the cut grass and 8.0 to 10.0% 2.0 to 4.0% by weight of powder, 2.0 to 4.0% by weight of anthracite, 1.0 to 3.0% by weight of loess powder, and 2.0 to 4.0% by weight of oil sludge are mixed and mixed evenly (material mixing step).
Then, the mixed material is placed in a cylindrical or rectangular tube-shaped mold, and the resultant is compressed at a pressure of 0.5 to 1.5 tons / cm < 2 > for 5 to 20 minutes to form a pulverized coal (carbon molding step) When the pulverized coal is discharged from the mold and dried naturally for one to two days in a place where moisture is not permeated (the pulverized coal is dried), the pulverized coal of the present invention as shown in the following FIG. 2 is obtained.
Figure 2. Image of the pulverized coal according to the present invention
However, the present invention is not limited to this, and various shapes and various sizes can be manufactured according to the type of the molding die and the size of the molding die.
The thus-produced pulverized coal according to the present invention can be used for various purposes.
For example, it can be used as a fuel for a heating device such as an office or a vinyl house heating stove used for growing plant crops, or as a fuel instead of a conventional lightening stove for cooking meat.
As described above, the smoke generated when the pulverized coal according to the present invention is burned contains almost no harmful components such as dust, sulfur oxides and nitrogen oxides generated when fossil fuels such as coal are burned so that air pollution is not generated, Ash can be used as a soil modifier, which is economically very useful because the ash reprocessing cost is greatly reduced compared to fossil fuels such as coal.
In addition, when the pulverized coal according to the present invention is burned to cook the meat, the smell of the grass is included in the smoke generated when the pulverized coal is burned, so that the flavor of the grilled meat improves the taste, .
