Description

저질무연탄을 주제로 한 구멍탄의 제조방법Method for manufacturing hole coal based on low anthracite coal

본 발명은 저질무연탄을 주제로 한 구멍탄의 제조방법에 관한 것으로, 저질무연탄과 식물의 탄화물을 주제로하여 착화력을 돕기위한 불랙카본과 연소를 돕고 연탄성형시 점결력을 돕는 석회분을 혼합한 공지의 연탄 배합물에서, 황산수소칼륨 수용액에 산화토륨을 혼합한 용액에 소량의 산화세륨을 혼가한 혼합물을 식물탄화물에 분무한 것을 저질무연탄에 혼합하여 연탄을 제조 함으로서 1,000~2,500Cal 정도의 저질무연탄을 이용하여 4,500Cal 이상의 열량을 갖는 양질의 구멍탄을 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a hole coal based on low anthracite coal, which is a mixture of a low carbon anthracite and a carbon of a plant and a lime carbon to assist the ignition and burning and to aid coking during briquetting. In the coal briquettes blend, a mixture of a mixture of a small amount of cerium oxide in a solution of potassium hydrogen sulfate solution and a mixture of a small amount of cerium oxide was sprayed onto plant carbide to mix low anthracite coal to produce briquettes of about 1,000 to 2,500 cal. The present invention relates to a method for producing a high quality coal with a calorific value of more than 4,500 cal.

종래에도 저질무연탄과 식물탄화물을 주제로하고 여러가지의 산화제를 혼합하여 연소시 산소의 자체 공급으로 연소효율이 높혔거나 각종 조연제 또는 연소촉진제로서 질산카륨, 질산스트론둠, 염소산칼륨, 망초, 황산소오다등을 저질 연탄이나 착화탄에 혼합하여 무독연탄 또는 고열, 고칼로리 연탄을 제조한 예가 많으나, 이들은 모두 산화제 또는 연소촉진제 등의 단순한 작용에 의하여 저질, 저칼로리의 연탄을 연소시 연소를 촉진하거나, 산소의 발생공급으로 연소를 촉진하여 완전 연소를 도모하기는 하였으나 이들 방법은 모두 고열, 고칼로리의 열량을 내면서 장기간 연소 즉, 유해까스의 발생이 없이 지속적 연소를 하지 못하고 짧은 시간에 연소시키는 역활밖에는 할수 없었고, 이에 따라 연소시간을 연장하기 위해서는 저질무연탄의 배합비율을 높여야 하기 때문에 저질무연탄과 중질무연탄의 배합 비율을 높혀야 할뿐만 아니라 저질무연탄을 많이 사용할시에는 연소가 불량하기 때문에 적어도 2,500Cal 이상의 중질무연탄을 많이 사용해야하는 결점으로 저질무연탄을 이용한 구멍탄의 제조방법 본래의 목적에 부합되지 못하는 결점이 있었고, 또 금속산화제를 분말화하여 혼합 이용한 것들은 산화제로서의 화학적촉매 작용으로 탄소 함량이 낮은 저질탄의 착화연소 효력을 얻을 수 있으나, 금속산화제가 포함된 광석의 구득난과 분쇄작업등의 번거로움으로 그 생산원가가 높고 배합비율을 조정하기가 어려운 결점도 있었다.Conventionally, low anthracite coal and plant carbide are mixed and various oxidants are mixed to increase combustion efficiency by supplying oxygen itself during combustion, or as various fuels or combustion promoters, such as carium nitrate, strontium nitrate, potassium chlorate, manganese, sulfuric acid In many cases, non-toxic coal or high-temperature, high-calorie briquettes are manufactured by mixing soda and the like with low-quality briquettes or complex coals, but all of them promote combustion of low-quality and low-calorie briquettes by a simple action such as an oxidizing agent or a combustion accelerator. In addition, although these methods promote complete combustion by accelerating combustion with the generation of oxygen, all of these methods produce high heat and high calorie calories, and burn them in a short time without continuous combustion without the occurrence of harmful cutlet. In addition, the compounding ratio of low anthracite coal was increased in order to prolong the combustion time. In order to increase the mixing ratio of low anthracite coal and heavy anthracite coal, and to use a lot of low anthracite coal, combustion is poor. There was a flaw that was not inherent to the original purpose, and powdered metal oxidants were mixed and used to obtain the complex combustion effect of low carbon with low carbon content due to the chemical catalytic action as an oxidant, but Due to the hassle of grinding, the production cost is high and it is difficult to adjust the mixing ratio.

본 발명은 상기와 같은 종래 저질무연탄을이용한 고열, 고칼로리 연탄의 결점을 완전 개량하여 종래공지의 각종 저질무연탄을 이용한 연타배합물에 황산수소칼륨과 산화토륨 및 산화세륨을 본 발명 방법으로 배합한 것을 혼합하므로써, 최저질탄을 사용하여 완전 연소는 물론 고열, 고칼로리의 열량을 발하면서 특히 장시간 연소를 지속시킬 수 있게 한 저질탄을 이용한 무득연탄의 제조방법에 관한 것으로서, 이를 실시예를 들어 상세히 설면하면 다음과 같다.The present invention is a mixture of potassium hydrogen sulfate, thorium oxide, and cerium oxide in the battered mixture using various low quality anthracite coals of the prior art by completely improving the defects of high temperature and high calorie briquettes using the conventional low anthracite coal. By mixing, it relates to a method for producing coal briquettes using low-quality coal, which allows the combustion of not only complete combustion but also high-temperature and high-calorie calories, and particularly long-lasting combustion. As follows.

즉, 탄광에서 폐석화하는 1,000~2,500Cal 정도의 저질무연탄과 수종갱신의 대상이 되는 임산물 및 그밖의 식물성탄화물에 저질탄의 착화력을 부여하는 불랙카본과 연탄 점결제인 석회분을 혼합하여 공지의 연탄조성물을 조성함에 있어 25% 황산수소칼륨 수용액에 산화토륨(ThO2)과 산화세륨(CeO2)을 1:2의 비로한 혼합물이 약 15% 함유되게 혼합하여서된 혼합액을 식물성 탄화물에 분무하여 건조시킨 후, 공지의 저질무연탄과 카본불랙, 석회석 등이 혼합된 분탄에 혼합하여 본 발명 구공탄을 제조한다. 이때 저질무연탄의 발열량에 따라 상기 분무혼합액의 혼합비를 가감하여 배합하면 되는 것으로 이의 실시예를 들면 다음과 같다.In other words, coal briquettes are mixed with low anthracite coals of about 1,000 to 2,500 cales from coal mines, black carbon and briquette binders that give low-carbon coal ignition to forest products and other vegetable carbides. In preparing the composition, a mixture of 25% potassium hydrogen sulfate solution containing about 15% of a mixture of thorium oxide (ThO 2 ) and cerium oxide (CeO 2 ) in a ratio of 1: 2 is sprayed onto the vegetable carbide and dried. After making it, the well-known low anthracite coal, carbon black, limestone, etc. are mixed with the powdered coal mixed to manufacture the ball coal of the present invention. In this case, the mixing ratio of the spray mixture may be added or subtracted according to the calorific value of the low anthracite coal.

[실시예 1]Example 1

발열량 1,000Cal의 저질탄 50%에 산화토륨(ThO2)과 산화세륨(CeO2)이 1:2의 비로 배합된 혼합물이 약 15%함유된 25%황산수소칼륨의 혼합액을 분무한 탄화질 40% 및 블랙카본 5%, 석회분 3%, 제오라이트 2%의 비율로 배합하여 일반성형기로 구멍탄을 성형하고,40% of carbonized carbon sprayed with a mixture of 25% potassium hydrogen sulfate containing about 15% of a mixture containing 50% of the calorific value of calorific value of 1,000 cal and thorium oxide (ThO 2 ) and cerium oxide (CeO 2 ) in a ratio of 1: 2. And 5% black carbon, 3% lime, and 2% zeolite at a ratio of forming a hole coal by using a general molding machine.

[실시예 2]Example 2

발열량 2,000Cal의 저질탄 60%에 상기 혼합액을 분무한 탄화질 30% 및 블랙카본 5%, 석회분3%, 제오라이트 2%의 비율로 배합하여 구멍탄을 성형한다.60% of low calorie coals having a calorific value of 2,000 cal are sprayed with a mixture of carbonaceous material 30%, black carbon 5%, lime powder 3%, zeolite 2%, and a coal briquette is formed.

이상의 실시예에서와 같이 제조된 연탄은 모두 4,000Cal 이상의 열량을 낼수 있는데, 상기 실시예에서 밝힌바와 같이 발열량이 적은 지질탄일수록 그 혼합비와 혼합액을 탄화질의 혼합비가 반비례하게됨을 알 수 있다.The briquettes manufactured as in the above examples can all produce more than 4,000 calories of calorie, and as shown in the above example, it can be seen that the less the calorific value of the coal coal is, the mixing ratio of the carbonaceous mixture is inversely proportional to the mixing ratio.

이상에서 본원의 특징인 황산수소 칼륨수용액과 산화토륨 및 산화세륨의 혼합액의 작용효과를 보면 황산수소칼륨은 쉽게 물에 녹아서 금속산화물인 산호토륨 및 산화세륨과 잘 혼합되어 연탄성형시 각종 배합물을 균일하게 혼합되게 하면서 연탄연소시 가열되어 피로황산칼륨을 거쳐 황산 칼륨으로 변하여 금속산화물인 산화토륨과 산화세륨의 가열, 발열을 도와주어 산화토륨이 쉽게 가열되게 하여 연탄연소시 산화작용으로 조연역활을 하게하고, 또 산화세륨은 산화토륨 자체만으로는 고온발생이 안되기 때문에 산화세륨에 의하여 쉽게 고온으로 광휘를 발할 수 있게 하는 역활을 한다.In view of the effect of the mixture of the aqueous solution of potassium hydrogen sulfate and thorium oxide and cerium oxide, which is the characteristic of the present application, potassium hydrogen sulfate is easily dissolved in water and mixed well with coral thorium and cerium oxide, which are metal oxides, to uniformly blend various compounds during briquetting. It is heated during briquette combustion and converted to potassium sulfate through potassium pyrosulphate to help the heating and heating of thorium oxide and cerium oxide, which are metal oxides, and to easily heat the thorium oxide so that it acts as a supporting role by oxidation during briquette combustion. In addition, since cerium oxide does not generate a high temperature only by thorium oxide itself, cerium oxide plays a role of making it easy to emit brightness at high temperature by cerium oxide.

따라서, 최저질무연탄의 연소효율을 탄화물과 함께 높이게 되는 효과가 있어 우리나라 널리 분포되어 있는 탄광의 무연탄 폐석을 이용하게 됨으로 자원활용의 장점과 외국으로부터 비싸게 구입되는 양질의 석탄을 수입하지 않게되는 잇점이 있는 것이며, 고온으로 연소되기 때문에 완전연소에 의하여 연탄가스 발생을 저하시키는 효과도 있는 것이다.Therefore, it has the effect of increasing the combustion efficiency of the lowest anthracite coal together with carbides, so it uses the anthracite waste-rock of coal mines widely distributed in Korea, so it has the advantage of resource utilization and the advantage of not importing high quality coal purchased expensively from abroad. Since it burns at high temperature, it also has the effect of reducing briquette gas generation by complete combustion.
