Hereinafter, the present invention will be described in more detail.

The present invention provides a fuel composition comprising a fertilizer on the back of a person.

In the present invention, the term " homogenized soil on the back and the like "means that the larvae are excreted after digestion and digestion of organic waste. The fecal soil may be a whole product obtained by treating organic wastes or the like, or may be a product obtained by separating the fecal soil from the fecal soil after the production of the fecified soil to remove the dirt and the like.

The period of growing from an egg to an adult is 37 to 41 days, and the period of a larval state serving as a decomposer is about 14 days. When 5,000 larvae are fed to 10kg of food waste, about 80% of the food waste is decomposed in about 5 days. The volume of the broken food waste is about 42% and the weight is reduced to about 70%. The larvae of Donghae are much more effective in treating organic wastes such as Donghae because the period of decomposing organic waste resources is longer than earthworm or housefly.

It is difficult to live when the larva is less than about 27 캜, and the larva is actively moving at about 30 캜 to 42 캜, and the organic waste is treated to produce the fecal soil. In addition, larvae such as the larvae have a habit of crawling outward to find a dry place to become a pupa after about 14 days, which is the period of the larva that can decompose organic wastes.

And the like for treating the organic waste according to the present invention can be used in the form of egg, larva, or mixture thereof. The number of individuals to be added to the organic wastes may be 100 to 1000 wastes per 1 kg of organic wastes. The breeding of the above-mentioned animals can be carried out at a temperature of 30 to 42 DEG C for 3 to 14 days.

Larvae obtained after treating organic wastes are economical because they can be used as raw materials for oil extraction. The above-mentioned maintenance can be made by using the homogenization generated in the production process of the feces and the like in the home and the like, and it is possible to secure a certain heat-generating performance by including the fuel in the fuel composition and the like, Can be produced.

In addition, when the fuel composition is solidified, the fuel composition can be lubricated during the molding process to lower the molding pressure, as well as to reduce the defects in the solidified fuel composition and increase the durability and thermal efficiency.

The present invention relates to a fuel composition containing fecal fertilizer obtained by treating organic wastes using drought and the like, and the organic wastes which can be treated with the feces and the like can be livestock manure, organic sludge, food waste, and the like, Do not. For example, the organic waste is at least one selected from the group consisting of livestock manure, organic sludge, and food waste.

According to one embodiment of the present invention, a fuel composition can be prepared mainly based on fecal soil or the like, or can be added to fuel of wood pellets conventionally. The homogenate may include 0.5 to 100 parts by weight, for example 1 to 99 parts by weight, 10 to 90 parts by weight, 30 to 50, or 30 to 40 parts by weight, based on 100 parts by weight of the solid content of the fuel composition .

The lower the moisture content of the fecified soil is, the more favorable the combustion efficiency is, for example, 20% or less. Also, considering the time and cost of drying the fecal soil, the water content may be somewhat higher. Therefore, it is possible to determine the water content of the appropriate fodder soil considering the combustion efficiency, the drying time and the cost, and the stability of the fuel, for example, it may be 1 to 20% or less, or 7 to 15% or less. When the water content of the feces is too low, it is advantageous in terms of combustion efficiency but it takes a long time to dry and the stability after molding may be deteriorated. When the water content is too high, defects such as defects Can occur.

The term "moisture content" refers to the ratio of the weight of water to the total weight of the fecal soil, where w ₁ is the weight of water in the foliar soil and w ₂ is the total weight of the flesh Calculated using Equation 1.

As shown in FIG. 3, it was confirmed that the fuel composition including the feces-modified soil according to the present invention is actively combustible and can be usefully used as a solid fuel.

Example 5. Pellet molding

Implementation and bunbyeonto example embodiment obtained in 3 dry dongae obtained in Example 3 or the like, the maintenance, and waste wood, the pellets in the same manner as 4, substantially in is conducted except that the molding by adding a molding binder, etc. dongae was prepared .

Example 6. Quality analysis of pellets

The method of measuring the calorific value, the recycling rate, and the water content of the pellets prepared in Examples 4 and 5 is described in Article 5 (Quality (Quality) of Wood Pellet Quality Standard of the National Forestry Academy Notice No. 2009-2 And quality test standards).

6-1. Calorimetric measurement

The calorific value of the pellets was calculated by calculating the calorific value from the change in temperature before and after combustion by charging 0.5 g of the dried sample into a calorimeter (Parr 6 calorimeter), filling it with oxygen and igniting it.

As a result, the calorific value of the manufactured pellet product exceeded the first grade (4,300 kcal / kg) of the quality standard, and since the wood used is the same, there is no difference in calorific value due to the characteristics of the wood, I could see.

The pellets added with oil to Dongae et al. Showed higher calorific value than the pellets without oil added to Dongae. This is due to the fact that the chemical specificity of fats and oils in Donga et al. Is considered to be an important factor affecting combustion efficiency by increasing calorific value during pellet combustion.

6-2. Measuring quantity

As a method of measuring the amount of ash, 1 g of a sample is subjected to a combustion test by a temperature raising schedule (60 minutes at 250 ° C and 120 minutes at 575 ° C) determined by the test method prescribed in the quality standard in a furnace, Respectively.

As a result, the ash content of the pellets ranged from 0.34 to 0.42% on the average of less than 0.7% of the first grade of the quality standard, and it was judged to be high quality pellets usable for domestic and power generation.

6-3. Measurement of water content of pellets

The water content of the prepared woody pellets was measured by drying the weighing bottle with the cover at 105 ± 3 ° C and then from the desiccator to room temperature. 20 g of pellets were weighed into a uniform layer in a weighing bottle and weighed, including the cover. The lid was then removed and dried at 105 ± 3 ° C until the weight of the dish containing the sample remained unchanged, then covered in an oven and allowed to cool to room temperature in a desiccator. After this process, the water content was calculated using the following equation (2).

[Equation 2]

M _ad (%) = (m ₂ - m ₃ ) / (m ₂ - m ₁ ) * 100

M _ad = Moisture content of water based pellets

M ₁ = empty weighing bottle + weight of cover

As a result, the moisture content of pellets in Donghae and others satisfies the first grade 10% or less of the quality standard of wood pellets. In general, the pelletization of wood is performed by a heat treatment effect generated by a roller rotating at a high speed when the sawdust is put into a mold with dies and rollers attached thereto, and by a high pressure, holes are laminated in small amounts and compressed to 2.5 to 3 times. In this process, the wood is plasticized, the wood is fluidized, the sawdust is bonded, the water is evaporated, and the water content is evaporated through the air after the molding machine is exposed to air or cooled. Therefore, the wood pellet product generally has a water content of less than about 10%. In this experiment, the pellet moisture content was less than 10% as a result of the compression and molding process.
