The calorific value of the coal briquettes prepared in Examples 1 to 6 is shown in Table 2 below, and the calorific value of the coal briquettes manufactured according to the method for producing coal briquettes using the waste of the present invention was requested to the Korea Testing and Research Institute. The results are shown in FIG. 3.

[Table 2]

As can be seen from the results in Table 2, it was confirmed that the coal briquettes prepared in Examples 1 to 3 according to the present invention all contained a high calorific value of 5,500 kcal / kg or more.

However, the coal briquettes prepared in Example 1 was found to have a lower calorific value than the coal briquettes prepared in Examples 2 and 3, which means that the livestock waste and anthracite coals increase the calorific value of the coal briquettes as compared to Examples 2 and 3. It seems to have been used at low weight percent.

In addition, the coal briquettes prepared in Example 3 was found to have a higher calorific value than the coal briquettes prepared in Examples 1 and 2, which means that the livestock waste and anthracite coals having higher calorific value of the coal briquettes are higher than those of Examples 1 and 2. It seems to have been used in weight percent.

However, considering that there is no significant difference from the calorific value of Example 2 and that the consumption of food waste and sludge is relatively reduced as the weight percent of livestock waste is increased, the weight percent of livestock waste is Example 2 It can be seen that it is desirable to maintain about 5.4% by weight used at.

On the other hand, as can be seen through the results of Table 2, the coal briquettes prepared in Examples 4 to 6 was found to have a lower calorific value than the coal briquettes prepared in Examples 1 to 3 according to the present invention, which is high, Different from Examples 1 to 3 in which anthracite powder containing a calorific value is added, it seems to be due to the addition of atan powder, lignite powder and coke powder containing a lower calorific value than anthracite powder.

In addition, the coal powder, lignite powder and coke powder contain calorific value in the order of the order of coal fraction <lignite powder <coke powder, and thus, the calorific value of the coal briquettes prepared in Examples 4 to 6 is also carried out in Example 4 < Example 5 <It turned out that it is remarkable in order of Example 6.

In addition, according to the measurement results shown in FIG. 3, the low calorific value of the coal briquettes using the waste according to the present invention was 23250 J / g, and the high calorific value was measured to be 24610 J / g, which is 1 kcal of 4.186 kJ in consideration of kcal / kg. In terms of units, the low calorific value is 5,554 kcal / kg, and the high calorific value is confirmed to be 5,879 kcal / kg. The coal briquettes using waste according to the present invention have both a low calorific value and a high calorific value of more than 5,500 kcal / kg. It turned out that it contains a high calorific value.

As a result, the coal briquettes using the waste according to the present invention can be produced from fuel containing a high calorific value of 5,000 to 7,000 kcal / kg by adding livestock waste and anthracite to food waste and sludge containing low calorific value. In addition, the use of both organic and inorganic wastes expands the scope of waste recycling and can be used as fuel in various fields, including home and industrial.
