본 발명은 팜 껍질과 석탄을 혼용하여 보일러용 바이오매스 연료를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a biomass fuel for a boiler by mixing palm shell and coal.

최근, 이산화탄소 배출로 인한 다양한 문제가 발생함에 따라, 세계적으로 가스 배출을 줄이기 위한 연구가 급증하고 있으며, 화석 연료의 고갈이 예정되어 있는 상황에서 대체 가능한 에너지 개발에 대한 정부 및 기업 등의 관심이 높은 상황이다.Recently, due to various problems caused by carbon dioxide emissions, researches to reduce gas emissions are increasing worldwide, and there is a high interest of governments and corporations for developing alternative energy in the event that the fossil fuel is depleted. Situation.

이러한 추세에 맞추어, 예를 들면 한국공개특허 제2007-0095361호와 같이, 다양한 재료를 이용하여 바이오매스 연료가 개발 및 생산되고 있으나 상업성, 생산성, 자연 친화성 면에서 아쉬움이 있을 뿐만 아니라 연소시 발생하는 배출가스로 인하여 사용 설비의 수명을 단축시키는 문제점이 있다. 따라서, 상업성, 생산성, 자연 친화성이 보다 향상될 수 있을 뿐만 아니라 사용 설비의 수명까지 연장시킬 수 있는 바이오매스 연료의 개발이 시급한 상황이다.In line with this trend, for example, as disclosed in Korean Patent Laid-Open Publication No. 2007-0095361, biomass fuels are developed and produced using a variety of materials, but not only in terms of commerciality, productivity, and natural compatibility, There is a problem of shortening the life of the equipment used due to the exhaust gas. Therefore, there is an urgent need to develop biomass fuels that can not only improve commerciality, productivity, and natural friendliness, but also extend the life of the equipment used.

특히, 화력 발전에 있어서 우드 펠릿과 석탄을 혼소하는 방법에 대한 시도가 있었지만, 연소 과정에서 발생되는 황산칼슘으로 인하여 보일러 수명이 단축되는 문제점으로 인하여 혼소 비율이 3~5% 정도에 머물고 있는 실정이다. 따라서, 사용 설비의 수명을 유지 또는 연장시키는 동시에 팜 껍질의 혼소 비율을 최대 90~10% 정도로 높일 수 있는 기술의 개발이 절실하다.In particular, there have been attempts to mix wood pellets and coal in thermal power generation, but the mixing ratio remains at 3 to 5% due to the problem of shortening the boiler life due to calcium sulfate generated during the combustion process. . Therefore, there is an urgent need to develop a technology capable of maintaining or extending the service life of the equipment and at the same time increasing the mixing ratio of the palm bark to about 90% to 10%.

Could be.

상기한 바와 같이 제안되는 본 발명에 의한 팜 껍질과 석탄을 혼용하여 보일러용 바이오매스 연료를 제조하는 방법은, 팜 껍질이 1차 가열되는 1차 가열 단계; 상기 가열된 팜 껍질이 분쇄되는 분쇄 단계; 상기 분쇄 단계를 거친 팜 껍질로부터 유지 성분이 제거되는 유지제거 단계; 상기 유지제거 단계를 거친 팜 껍질과 석탄이 혼합되는 혼합 단계; 상기 혼합 단계에서 혼합된 연료혼합물이 기 설정된 형상으로 성형되는 성형 단계; 및 상기 성형된 연료혼합물이 포장되는 포장 단계;를 포함하는 것을 특징으로 한다.The method for producing a biomass fuel for a boiler by using a mixture of palm husk and coal according to the present invention as described above comprises: a primary heating step in which the palm husk is first heated; A grinding step of grinding the heated palm shell; An oil and fat removal step in which a fat or oil component is removed from the palm shell subjected to the grinding step; A mixing step in which the palm husk and coal which have undergone the maintenance removal step are mixed; A molding step in which the fuel mixture mixed in the mixing step is molded into a predetermined shape; And a packaging step of packaging the molded fuel mixture.

상기한 바와 같이 본 발명에 의한 팜껍질과 석탄을 혼용하여 보일러용 바이오매스 연료를 제조하는 방법에 의하면, 바이오매스 연료를 연소하는 과정에서 발생되는 황산칼슘 및 이산화탄소의 양을 최소화할 수 있다. 따라서, 보일러 등과 같은 사용 설비에 점착되는 이물질이 최소화되므로, 사용 설비의 수명이 연장될 수 있다. As described above, according to the method of manufacturing a biomass fuel for a boiler by mixing palm shell and coal according to the present invention, the amount of calcium sulfate and carbon dioxide generated in the process of burning the biomass fuel can be minimized. Therefore, since foreign matter adhering to the use facility such as a boiler is minimized, the service life of the use facility can be extended.

In addition, since the generation amount of harmful gases such as calcium sulfate and carbon dioxide can be reduced, there is an advantage that can minimize the environmental pollution due to the combustion of the biomass fuel.

그리고, 사용 설비의 수명에 대한 영향이 적으므로, 바이오매스 연료의 혼소 비율을 더욱 높일 수 있으므로, 바이오매스 연료의 연소 열량을 증대시킬 수 있는 이점이 있다.In addition, since the influence on the service life of the use facility is small, the mixing ratio of the biomass fuel can be further increased, and thus there is an advantage that the amount of heat of combustion of the biomass fuel can be increased.

이하에서는 본 발명에 의한 팜 껍질과 석탄을 혼용하여 보일러용 바이오매스 연료를 제조하는 방법의 실시예를 첨부한 도면을 참조하여 보다 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings, an embodiment of a method for producing a biomass fuel for a boiler by mixing a palm shell and coal according to the present invention will be described in more detail.

도 1은 본 발명에 의한 팜 껍질과 석탄을 혼용하여 보일러용 바이오매스 연료를 제조하는 방법의 제 1 실시예를 보인 플로차트이다.1 is a flowchart showing a first embodiment of a method for producing a biomass fuel for a boiler by mixing palm shell and coal according to the present invention.

도 1을 참조하면, 본 발명에 의한 팜 껍질과 석탄을 혼용하여 보일러용 바이오매스 연료를 제조하는 방법에 따르면, 먼저 팜 껍질이 중온 환경에서 가열된다(S11). 상기 팜 껍질은 PKS(Palm Kernel Shell)이라고도 칭한다. 이때, 상기 팜 껍질은 70~100oC에 해당하는 중온 환경에서 가열되어, 상기 팜 껍질에 함유된 수분이 제거된다. Referring to Figure 1, according to the method for producing a biomass fuel for the boiler by mixing the palm shell and coal according to the present invention, first palm shell is heated in a medium temperature environment (S11). The palm shell is also called Palm Kernel Shell (PKS). At this time, the palm bark is heated in a medium temperature environment corresponding to 70 ~ 100 o C, the water contained in the palm bark is removed.

여기서, 연소를 위한 연료로 사용되는 석탄의 수분 함량이 통상적으로 8% 이하에 해당하는 것이 적정 수준임을 감안할 때, 상기 가열 과정을 통하여 상기 팜 껍질의 수분 함량이 9% 이하에 해당하도록 상기 팜 껍질의 수분이 제거됨이 바람직하다. 또한, 일반적으로 상기 팜 껍질의 가열 과정 즉, 수분 제거 과정이 5분 이내에 완료되는 것이 요구됨을 고려할 때, 상기 팜 껍질의 수분이 9% 이하 수준으로 5분 이내에 제거되기 위해서는, 70oC 이상의 중온 환경이 필요하다. 즉, 70oC 미만의 온도 조건에서는 상기 팜 껍질의 수분이 9% 이하 수준으로 5분 이내에 제거되기 어려운 것이다. Herein, considering that the water content of coal used as fuel for combustion is usually at most 8%, the palm bark is 9% or less through the heating process. It is preferable that the moisture of is removed. In addition, considering that the heating process, that is, the water removal process, of the palm bark is generally required to be completed within 5 minutes, in order to remove the water of the palm bark within 5 minutes to a level of 9% or less, a medium temperature of 70 ° C. or higher. The environment is needed. That is, under the temperature condition of less than 70 ° C, the water of the palm bark is difficult to remove within 5 minutes to 9% or less.

한편, 상기 팜 껍질이 300oC 이상의 고온 환경에 노출될 경우에는, 상기 팜 껍질의 산화 현상이 발생하여 연료로서의 품질이 저하되게 된다. 또한 70~100oC 필요 이상의 고온으로 가열하지 않아도 됨으로 상기 팜 껍질의 수분 제거 과정은 70~100oC에 해당하는 중온 환경에서 이루어지는 것이 바람직하다.On the other hand, when the palm bark is exposed to a high temperature environment of 300 ° C or more, oxidation of the palm bark occurs, thereby deteriorating the quality as a fuel. In addition, it is preferable that the water removal process of the palm bark is performed in a medium temperature environment corresponding to 70-100 ° C. because it does not need to be heated to a high temperature of 70-100 ° C. or higher.

다음으로, 상기 가열된 팜 껍질이 분쇄된다(S12). 여기서, 상기 팜 껍질은 100~200 mesh의 입도를 가지도록 분쇄된다. 상기 팜 껍질을 분쇄하는 이유는 연소 효율을 향상시키기 위함이다. 또한, 상기 팜 껍질이 100 mesh 미만의 입도를 가지도록 분쇄되는 경우에는 연소 후에 연소 찌꺼기가 과도하게 남는 문제점이 있고, 상기 팜 껍질이 200 mesh를 초과하는 입도를 가지도록 분쇄하면 상기 팜 껍질의 섬유적 특성으로 인하여 균일한 입자 형성이 어려운 문제점이 있다. 따라서, 상기 팜 껍질은 100~200 mesh의 입도를 가지도록 분쇄됨이 바람직하다. Next, the heated palm shell is crushed (S12). Here, the palm shell is pulverized to have a particle size of 100 ~ 200 mesh. The reason for crushing the palm bark is to improve the combustion efficiency. In addition, when the palm shell is pulverized to have a particle size of less than 100 mesh, there is a problem that excessive combustion residues remain after combustion, and when the palm shell is pulverized to have a particle size of more than 200 mesh, fibers of the palm shell are Due to the red nature, there is a problem in that uniform particle formation is difficult. Therefore, the palm shell is preferably pulverized to have a particle size of 100 ~ 200 mesh.

다음으로, 팜 껍질에 포함된 유지 성분을 제거하는 과정이 수행된다(S13).Next, a process of removing the oil and fat contained in the palm peel is performed (S13).

보다 상세히, 고온 환경에서 2차적으로 가열된 팜 껍질은 용매에 혼합된 후 침전 현상을 이용하여 상기 팜 껍질에 포함된 유지 성분이 제거되는 과정이 이루어진다. 여기서, 상기 용매는 알코올이 해당될 수 있다. 상기 팜 껍질은 유지 성분과 셀룰로오스 성분을 포함하는데, 상기 침전 현상으로 인하여 상기 팜 껍질에 포함된 셀룰로오스 성분은 용기의 바닥에 가라앉고, 유지 성분은 상대적으로 상방에 뜨게 된다. 이러한 방식으로 분리된 상기 유지 성분 및 셀룰로오스 성분 중 상기 유지 성분을 제거함으로써, 상기 팜 껍질로부터 상기 유지 성분을 제거할 수 있는 것이다.In more detail, the palm bar heated secondarily in a high temperature environment is mixed with a solvent, and then a process of removing the oil and fat contained in the palm bark using a precipitation phenomenon is performed. Here, the solvent may correspond to alcohol. The palm husk comprises an oil and fat component and a cellulose component. The precipitation causes the cellulose component contained in the palm husk to sink to the bottom of the container, and the oil and fat component floats upward. By removing the said oil-fat component of the said oil-fat component and the cellulose component isolate | separated in this way, the said oil-fat component can be removed from the said palm shell.

그리고, 상기 유지 성분이 제거되고 남은 알코올과 셀룰로오스 성분의 혼합물이 저온 환경에서 건조되는 과정이 수행된다(S14). 이로써, 남아있는 알코올이 증발하고 셀룰로오스 성분만이 남게 되는 것이다. In addition, a process of drying the mixture of alcohol and cellulose components remaining after the oil and fat component is removed in a low temperature environment is performed (S14). As a result, the remaining alcohol evaporates and only the cellulose component remains.

한편, 팜 껍질과 별개로, 석탄이 건조 과정을 거치면서 석탄의 수분이 제거된 후(S15), 잘게 파쇄되는 과정이 수행된다(S16). On the other hand, apart from the palm husk, after the coal is removed during the drying process (S15), the finely crushed process is performed (S16).

그리고, 상기 유지 제거 과정을 거친 팜 껍질과, 상기 파쇄 과정을 거친 석탄이 혼합된다(S17). 이때, 상기 팜 껍질과 석탄의 혼합 비율은 최대 90~10% 해당하도록 혼합될 수 있다.Then, the palm husk through the oil and fat removal process, and the coal through the crushing process is mixed (S17). At this time, the mixing ratio of the palm shell and coal may be mixed to correspond to a maximum of 90 ~ 10%.

다음으로, 상기 혼합된 연료혼합물이 기 설정된 형상으로 성형된 후(S17), 포장되는 과정을 거쳐 바이오매스 연료가 완성된다(S18). Next, after the mixed fuel mixture is molded into a predetermined shape (S17), the biomass fuel is completed through the process of packaging (S18).

본 발명에 의하면, 석탄에 팜 껍질을 혼합한 바이오매스 연료를 제조할 수 있으므로, 연소시 화력을 더욱 향상시킬 수 있을 뿐만 아니라, 연소에 소요되는 석탄의 양도 보다 절약할 수 있는 이점이 있다.According to the present invention, since the biomass fuel in which the palm husk is mixed with coal can be produced, not only can the firepower be improved further during combustion, but also the amount of coal required for combustion can be further saved.

그리고, 팜 껍질에 함유된 유지 성분이 제거된 후 바이오매스 연료가 제조되기 때문에, 바이오매스 연료를 연소하는 과정에서 발생되는 황산칼슘 및 이산화탄소의 양이 최소화될 수 있다. 따라서, 보일러 등과 같은 사용 설비에 점착되는 이물질도 최소화되므로, 사용 설비의 수명이 연장될 수 있다. In addition, since the biomass fuel is manufactured after the oil and fat component contained in the palm husk is removed, the amount of calcium sulfate and carbon dioxide generated in the process of burning the biomass fuel may be minimized. Therefore, since foreign matter adhering to the use facility such as a boiler is also minimized, the service life of the use facility can be extended.

또한, 황산칼슘 및 이산화탄소와 같은 유해 가스의 발생량이 줄어들 수 있으므로, 바이오매스 연료의 연소로 인한 환경 오염을 최소화할 수 있는 이점이 있다. In addition, since the generation amount of harmful gases such as calcium sulfate and carbon dioxide can be reduced, there is an advantage that can minimize the environmental pollution due to the combustion of the biomass fuel.

그리고, 사용 설비의 수명에 대한 영향이 적으므로, 바이오매스 연료의 혼소 비율을 더욱 높일 수 있으므로, 바이오매스 연료의 연소 열량을 증대시킬 수 있는 이점이 있다. 상기 팜 껍질과 석탄의 혼합 비율 90~10% 즉, 바이오매스 연료의 혼소 비율을 최대 90% 까지 향상시키더라도, 연소시 발생되는 황산칼슘 등 사용 설비에 점착되는 이물질이 방지될 수 있으므로, 사용 설비의 수명에 영향없이 바이오매스 연료의 연소 열량을 더욱 증대시킬 수 있는 것이다. In addition, since the influence on the service life of the use facility is small, the mixing ratio of the biomass fuel can be further increased, and thus there is an advantage that the amount of heat of combustion of the biomass fuel can be increased. Even if the mixing ratio of the palm husk and coal is increased to 90 to 10%, that is, the mixing ratio of the biomass fuel is up to 90%, foreign substances adhering to the use equipment such as calcium sulfate generated during combustion may be prevented. It is possible to further increase the heat of combustion of the biomass fuel without affecting the life of.

이하에서는, 본 발명에 의한 팜 껍질과 석탄을 혼용하여 보일러용 바이오매스 연료를 제조하는 방법의 제 2 실시예에 대하여, 첨부한 도면을 참조하여 상세하게 설명한다. 본 실시예는, 제 1 실시예와 비교하여, 바이오매스 연료의 품질을 더욱 향상시킬 수 있는 2차 가열 과정이 추가되는 점에서 차이가 있으며, 제 1 실시예와 중첩되는 과정에 있어서는 제 1 실시예의 설명을 원용한다.EMBODIMENT OF THE INVENTION Hereinafter, the 2nd Example of the method of manufacturing the biomass fuel for boilers by mixing palm shell and coal by this invention is demonstrated in detail with reference to attached drawing.
