Description

커피박을 포함하는 고형연료 및 이의 제조방법{Solid fuel containing coffee waste and manufacturing method thereof} BACKGROUND OF THE INVENTION 1. Field of the Invention Solid fuel containing coffee waste and manufacturing method thereof

본 발명은 커피를 제조하고 나오는 찌꺼기인 커피박을 주원료로 이용한 고형연료 및 이의의 제조방법에 관한 것이다.The present invention relates to a solid fuel and a method for producing the same, using coffee meal, which is a residue from the production of coffee, as a main raw material.

여기서는, 본 개시에 관한 배경기술이 제공되며, 이들이 반드시 공지기술을 의미하는 것은 아니다.Herein, background art related to the present disclosure is provided, and these do not necessarily mean known art.

산업의 발전으로 필요한 에너지의 많은 부분을 화석연료에 의존하고 있으나 화석연료는 제한적이고 사용시에 각종 유해물질을 발생시키고 있으므로 화석연료를 대체할 수 있는 친환경적 에너지를 찾는데 많은 관심을 기울이고 있다.Although much of the energy required by the development of the industry relies on fossil fuels, fossil fuels are limited and generate various harmful substances when used, so much attention is paid to finding eco-friendly energy that can replace fossil fuels.

또한 산업의 발전으로 각종 쓰레기 특히 산업폐기물이나 생활 폐기물의 발생량이 많아져 이를 처리하기 위해서 많은 비용을 소비하고 있다. 이에 폐기물을 이용하여 에너지를 생산할 수 있는 기술이 개발되고 있다.In addition, due to the development of the industry, the generation of various wastes, especially industrial wastes and household wastes, increases, and a large amount of cost is consumed to treat them. Accordingly, a technology capable of producing energy using waste is being developed.

일반적으로, 유기물은 열분해(thermal decomposition)를 통해 숯과 같은 탄소고체, 오일 또는 가연성 가스 등의 열분해 생성물이 된다. 예를 들어, 목재를 열분해하면 목초액, 나무 타르, 목탄 등을 제조할 수 있고, 석탄을 열분해 하여 석탄 가스, 타르, 코크스 등을 얻기도 한다. 특히, 최근에는 석탄, 석유 등의 화석 에너지를 대체할 수 있는 대체 에너지로써 상기 유기물을 이용하는 바이오매스(bio mass)에 관한 연구 및 개발이 활발하게 진행되고 있다.In general, organic matter becomes a thermal decomposition product such as carbon solids such as charcoal, oil or combustible gas through thermal decomposition. For example, when wood is pyrolyzed, wood vinegar liquid, wood tar, charcoal, etc. can be produced, and coal gas, tar, coke, etc. can be obtained by pyrolyzing coal. In particular, in recent years, research and development on biomass using the organic material as an alternative energy that can replace fossil energy such as coal and petroleum are actively progressing.

커피박은 바이오매스의 한 종류로서 목재, 볏짚 등 일반적으로 고형 연료화 되고 있는 바이오매스와는 달리 셀룰로오스, 헤미셀룰로오스, 리그닌 이외에 유지성분이 16% 이상 함유되어 있고 회분함유량 1.75%로 10% 이상인 석탄에 비해 현저히 낮으며, 발열량 4,664kcal/kg으로 1급 목재펠릿 발열량 기준인 4,300kcal/kg을 상회하는 연료 특성이 우수한 바이오매스 자원이다. Coffee meal is a type of biomass, and unlike biomass that is generally solid fuel such as wood and rice straw, it contains more than 16% oil and fat in addition to cellulose, hemicellulose, and lignin. It is a biomass resource with excellent fuel characteristics with low calorific value of 4,664 kcal/kg, which exceeds 4,300 kcal/kg, the calorific value of first-class wood pellets.

이러한 중요한 에너지 자원임에도 불구하고 산업폐기물로 분류되어 현재까지 에너지 자원으로서의 이용가치를 인식하지 못한 점도 있었지만 에너지수율을 높일 수 있는 적절한 방법을 찾지 못하고 있는 실정이다. 또한 커피박은 석탄에 버금가는 발열량을 가지고 있지만 가루상태나 펠릿 상태의 커피박을 단일로 연소시키면 연소속도가 느리고 불꽃을 일으키지 못하며 연소속도의 지연으로 에너지 수율이 낮아지는 문제점이 있었다.Despite such an important energy resource, it was classified as an industrial waste, so there was a point in which the value of use as an energy resource was not recognized until now, but an appropriate method to increase the energy yield has not been found. In addition, coffee foil has a calorific value comparable to that of coal, but when a single combustion of powdered or pelletized coffee foil has a problem, the combustion speed is slow and the flame cannot be generated, and the energy yield is lowered due to the delay of the combustion speed.

본 발명은 기존 무연탄의 대체가 가능하며, CO, CO2 등 유해가스 발생이 저감되고, 연소 후에도 형상이 유지되는 고형연료 및 이의 제조방법을 제공하고자 한다. An object of the present invention is to provide a solid fuel that can be replaced with existing anthracite, reduce the generation of harmful gases such as CO and CO 2 , and maintain its shape even after combustion, and a method of manufacturing the same.

교반식 로스터 기를 이용하여 하기 표 1에 나타낸 것과 같이 온도는 210℃ 내지 290℃까지 20℃ 간격으로 5구간, 시간은 20분 내지 50분까지 10분 간격으로 4구간을 설정하여 커피박을 탄화시켰다. 탄화시 산소의 유입을 최대한 차단하기 위해 외부의 공기 유입을 차단하였으며, 내부에 질소를 투입하여 제한된 공기를 유지하였다.As shown in Table 1 below, the coffee leaf was carbonized by setting 5 sections at intervals of 20°C to 210°C to 290°C, and 4 sections at intervals of 10 minutes to 20 to 50 minutes using an agitated roaster. . In order to block the inflow of oxygen as much as possible during carbonization, the inflow of external air was blocked, and nitrogen was added to the inside to maintain limited air.

상기 조건으로 제조된 탄화 커피박의 질량 수율(mass yield) 및 발열량(Lower Heating Value)을 측정하여 하기 표 1에 나타내었다. 하기 표 1에 나타난 것과 같이 탄화 공정별 질량 수율은 온도와 시간이 증가할수록 감소하는 것을 알 수 있다. 발열량의 경우 하기 표 1에 나타난 것과 같이 탄화 온도 210℃에서는 기존 커피박의 발열량보다 낮은 발열량을 가지는 것을 확인할 수 있다. 또한 탄화 공정을 거치지 않은 커피박의 발열량(5,320Kcal/Kg)을 기준으로 240 내지 300℃ 온도에서 35 내지 55분 동안 로스팅한 경우 발열량이 대체로 우수한 것을 확인할 수 있다. The mass yield and lower heating value of the carbonized coffee foil prepared under the above conditions were measured and shown in Table 1 below. As shown in Table 1 below, it can be seen that the mass yield for each carbonization process decreases with increasing temperature and time. In the case of the calorific value, as shown in Table 1 below, at a carbonization temperature of 210°C, it can be confirmed that the calorific value has a lower calorific value than the calorific value of the conventional coffee foil. In addition, it can be seen that when roasting for 35 to 55 minutes at a temperature of 240 to 300° C. for 35 to 55 minutes based on the calorific value (5,320 Kcal/Kg) of coffee foil that has not undergone a carbonization process, the calorific value is generally excellent.

탄화 공정별 커피박의 질량 수율과 발열량을 포함한 에너지 수율을 하기 식 1에 따라 분석한 결과를 하기 표 1에 나타내었다. The results of analyzing the energy yield including the mass yield and calorific value of coffee foil for each carbonization process according to Equation 1 below are shown in Table 1 below.

As shown in Table 5 below, it was confirmed that the durability of coffee briquettes after combustion was similar to that of anthracite (Example 7) up to a coffee content of 30% (Examples 1 and 2). The average compressive force of 50% coffee briquettes (Example 3) was 22.69N, which was reduced to half of the average compressive force of 46.72N of anthracite. In addition, it was confirmed that there was no breakage when removing the 20% to 70% coffee briquettes (Examples 1 to 5) used in the test with tongs from the stove after combustion.
