Abstract

A briqutte is prepd. from coal of low quality. The briqutte is composed of 50% coal of low quality, 20% graphite, 28% coal of high quality and 2% combustion accelerant. The combustion accelerant is composed of 70% calcium oxide, 5% ferric oxide, 5% potassium nitrate, 5% sodium hydrocarbonate, 5% soot and 10% briquette cinder. This process cuts down cost of production.

Description

폐탄을 이용한 구멍탄의 제조방법Method for manufacturing hole coal using waste coal

본 발명은 저질탄인 폐탄을 이용한 구멍탄의 제조방법에 관한 것이다.The present invention relates to a method for producing a hole coal using waste coal, which is low quality coal.

탄광에서 버려지고 있는 저질탄인 폐탄은 열량 부족으로 폐탄만으로는 구멍탄을 제조하여 사용할 수가 없는 것으로 그간 폐탄에 화학성분의 발화재 또는 조연제를 첨가하여 열량을 높여주는 방법이 제안되기도 하였으나 강제성과 실용성이 없어 실용화되지 못하였다.Waste coal, a low quality coal discarded in coal mines, cannot be produced by using only coal due to lack of calories.In the meantime, a method of increasing the calorie content by adding a chemical ignition material or a supporting agent to waste coal has been proposed. It has not been put to practical use.

본 발명의 목적은 이와같은 문제점을 해결하고져 한 것으로 국내의 어느 탄광에서나 많은 매장량이 있는 저질탄에 흑연, 고질탄을 일정량 혼합시켜 연소시에 충분한 열량을 얻고져 한 것이며 상기 혼합물의 완전연소를 위하여 연소촉진제를 혼합하여 구멍탄이 제조되게 한 것인바 본 발명을 실시예에 의하여 상세히 설명하면 다음과 같다.It is an object of the present invention to solve such a problem and to obtain sufficient calories during combustion by mixing a certain amount of graphite and high coal to low carbon having a large reserve in any coal mine in Korea, and burning for complete combustion of the mixture. When the coal is prepared by mixing the accelerator bar, the present invention will be described in detail by way of examples.

[실시예 1]Example 1

상기의 혼합물을 분쇄기로 80매쉬정도 분쇄하여 구멍탄을 제조하는 것으로 저질탄인 폐탄을 1/2이상 활용하여 구멍탄을 제조하는 것이 본 발명의 특징이다.It is a feature of the present invention to produce a hole coal by pulverizing the mixture of about 80 mesh with a grinder to produce a hole coal by utilizing 1/2 or more waste coal, which is a low quality coal.

고질탄은 일반적으로 구멍탄 제조에 사용되는 양질의 무연탄으로 비교적 높은 열량을 낼 수가 있는 것이나 상기 실시예에서는 폐탄의 혼합비율이 1/2 이상되어 구멍탄의 기준열량인 4,200킬로 칼로리를 발생시킬수가 없어 탄소성분의 흑연과 연소촉진제를 일정량 혼합시켜 열량을 높여주도록 한 것이다.High-quality coal is a high quality anthracite coal generally used in the manufacture of hole coal, which can produce relatively high calories, but in the above embodiment, the mixing ratio of the waste coal is 1/2 or more, and thus it is not possible to generate 4,200 kilocalories, which is the standard calorie of the coal. It is to increase the amount of heat by mixing a certain amount of graphite and the combustion promoter of the component.

본 발명은 이와같은 혼합물에 의하여 구멍탄이 제조되는 것으로 착화력을 좋게하는 연소촉진의 성분은 실시예 2와 같다.In the present invention, the coal is produced by such a mixture, so that the component of the combustion promotion to improve the ignition power is the same as in Example 2.

[실시예 2]Example 2

Figure kpo00002
Figure kpo00002

상술한 바와같이 혼합 구성되어 연소촉진제에서 산화제이철과 초석은 착화력을 좋게하는 것이나 산화제이철과 초석만으로 연소 촉진제를 구성시킬때 순간적인 발화만을 기대할 수 있어 실시예 1에 의한 혼합물의 완전연소는 이루어질 수가 없다.As described above, the ferric oxide and the cornerstone in the combustion accelerator to improve the ignition power can be expected only when the combustion accelerator is composed only of the ferric oxide and the cornerstone can be expected to ignite instantaneous combustion of the mixture according to Example 1 I can't.

따라서 산화제이철과 초석에 중조를 섞어 순간적인 발화를 지연시키는 것이며 질량이 거의 없고 부피가 큰 끄림을 혼합하여 혼합율을 높이고 충진제로서 흡착율이 좋은 석회와 연탄재를 혼합하여 연소 촉진제를 구성하게 되면 연소시 흡착력이 있는 석회와 연탄재가 일산화 탄소를 자체 흡수하여 연탄가스의 량을 상당히 줄일수가 있는 것이다.Therefore, admixture of ferric oxide and saltpeter delays the instantaneous ignition, and it mixes almost no mass and bulky drag to increase the mixing rate, and mixes lime and briquette with good adsorption rate as a filler to form a combustion accelerator. Lime and briquettes can absorb carbon monoxide by themselves and significantly reduce the amount of briquette gas.

이상에서 설명한 바와같이 본 발명은 저질탄인 폐탄에 흑연과 고질탄 등을 혼합시켜 구멍탄을 성형하는 것이므로 연소시에 기준열량 이상의 칼로리를 내면서 완전연소가 되면 연소촉진제에 의해 연소시간도 종래의 구멍탄에 비하여 길어지는 것이다.As described above, the present invention is to form a hole coal by mixing graphite and high coal with low coal waste coal, so that when the combustion is completed while burning calories above the reference calorie value, the combustion accelerator is also burned in comparison with the conventional coal coal. It will be longer.

따라서 본 발명은 저질탄인 폐탄과 연탄재 등의 폐기물을 이용하여 구멍탄을 제조하는 것이므로 산업상 활용가치가 큰 것으로 기존 구멍탄에 비하여 생산원가를 줄일수가 있을뿐만 아니라 연탄가스의 량도 상당히 줄일수가 있어 널리 보급하여 실용화 할수 있는 경제성이 매우 높은 발명인 것이다.Therefore, the present invention is to manufacture a hole coal by using waste coal such as waste coal and briquettes, which is low in coal, and thus has a high industrial utilization value, which can reduce production cost and significantly reduce the amount of briquette gas as compared to existing coal. The invention is very economical that can be put to practical use.
