Description
본 발명은 목재펠릿에 관한 것으로, 보다 상세하게는 발열량 향상, 제품 강도 개선, 오염물질 배출 저감 등의 성능 개선효과가 있는 반탄화(半炭火)된 산림바이오매스와 목타르를 이용한 고품질 펠릿의 제조방법 및 이를 이용한 고품질 펠릿에 관한 것이며, 환경부(한국환경산업기술원) 중소환경기업사업화지원사업인 ‘폐자원의 Up-cycling을 통한 고효율 친환경 고형연료 사업화’ 결과물이다.The present invention relates to wood pellets, and more specifically, a method for producing high-quality pellets using torrefied forest biomass and wood tar, which have performance improvement effects such as increased calorific value, improved product strength, and reduced pollutant emissions. and high-quality pellets using it, and is the result of the Ministry of Environment (Korea Environmental Industry and Technology Institute) small and medium-sized environmental enterprise commercialization support project, 'Commercialization of highly efficient, eco-friendly solid fuel through up-cycling of waste resources.'
최근에는 보일러를 가정용이나 소규모의 업무용으로 사용하는 일반농가, 축산농가, 낙농업 농가, 공장 등을 중심으로 펠릿 연료(Pellet fuel)를 이용할 수 있는 보일러의 보급 및 사용이 나날이 증가하고 있는 추세이다.Recently, the supply and use of boilers that can use pellet fuel is increasing day by day, mainly in general farms, livestock farms, dairy farms, and factories that use boilers for home or small-scale business purposes.
보일러의 연료로 사용되는 펠릿은 톱밥 또는 간벌에 의한 나무 등을 파쇄 한 후 압축하여 만든 연료로 석탄이나 석유와 같은 화석연료보다 이산화탄소의 배출량이 적고, 연소 후 남게 되는 잔존물이 적어 그 쓰임세가 급격하게 증가하고 있다. 특히, 농어촌과 같이 도시가스의 보급이 열악한 지역이나 대규모 축사나 낙농업 단지에서는 난방을 위하여 석유류에 비해 가격이 저렴한 펠릿의 사용이 더욱 증가하고 있다.Pellets used as fuel for boilers are fuel made by crushing sawdust or trees from thinning and then compressing them. They emit less carbon dioxide than fossil fuels such as coal or oil, and the residue left after combustion is small, so their use is rapidly increasing. It is increasing. In particular, in areas where city gas is poorly supplied, such as farming and fishing villages, or in large-scale livestock farms or dairy complexes, the use of pellets, which are cheaper than petroleum products, for heating is increasing.
현재 펠릿의 주 사용처는, 화력/바이오매스 혼소 발전소용으로 연간 150만톤 이상이 사용되며, 발전용 연료로 사용되는 펠릿은 대부분 수입산 목재 펠릿에 의존하고 있다. 국내에서 생산되는 펠릿은 대부분 가정용/산업용으로 사용되며, 연간 생산량은 약 20만톤이다.Currently, the main use of pellets is for thermal/biomass co-fired power plants, where more than 1.5 million tons are used annually, and most pellets used as fuel for power generation depend on imported wood pellets. Most pellets produced domestically are used for household/industrial purposes, and annual production is approximately 200,000 tons.
국산 펠릿의 발전용 펠릿 시장의 진출을 위해 단가가 낮은 수입산 목재 펠릿에 대한 국산 펠릿의 가격 경쟁력 확보를 위하여 저렴한 목재 펠릿 제조용 확보가 필요한 상황이다. In order for domestic pellets to enter the power generation pellet market, it is necessary to secure inexpensive wood pellet manufacturing in order to secure price competitiveness of domestic pellets against imported wood pellets with low unit prices.
따라서 기존에 폐기 처리 또는 퇴비 등의 원료로 사용되고 있는 임목부산물 (미이용 산림바이오매스)인 가지목 및 뿌리목 등을 국내 화력/바이오매스 혼소 발전소의 연료용 목재 펠릿으로 생산 기술 개발이 필요한 상황이다. Therefore, there is a need to develop production technology for wood pellets and root wood, which are forest by-products (unused forest biomass) that are currently used as raw materials for waste treatment or compost, into wood pellets for fuel in domestic thermal/biomass co-fired power plants.
또한, 산림바이오매스를 열분해로에서 열분해하는 경우 필연적으로 목타르가 발생한다. 이러한 목타르는 흑색의 유상물질로 점성이 높고, 굳어서 딱딱해지는 특징이 있다. 이러한 목타르는 열분해로를 폐색하는 원인으로 지목되기 때문에 주기적으로 제거해서 별도로 폐기하곤 했다.In addition, when forest biomass is pyrolyzed in a pyrolysis furnace, wood tar is inevitably generated. This type of wood tar is a black oily substance with high viscosity and has the characteristic of becoming hard when hardened. Since this wood tar was pointed out as a cause of clogging of pyrolysis furnaces, it was periodically removed and disposed of separately.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 해결하고자 하는 과제는 미이용 산림바이오매스를 마이크로웨이브로 반탄화하고, 열분해시 부산물로 나오는 목타르를 산림바이오매스와 혼합하여 고품질 펠릿의 제조방법 및 이를 이용한 고품질 펠릿을 제공하는 것이다.Therefore, the present invention was created to solve the above problems, and the problem to be solved by the present invention is torrefy unused forest biomass with a microwave and mix wood tar, which is a by-product of pyrolysis, with forest biomass. The purpose is to provide a method for manufacturing high quality pellets and high quality pellets using the same.

상기와 같은 본 발명의 목적은 또 다른 실시예로써, 전술한 제조방법에 의해 제조되는 것을 특징으로 하는 산림바이오매스와 목타르를 이용한 고품질 펠릿에 의해서도 달성될 수 있다. As another embodiment, the object of the present invention as described above can also be achieved by high-quality pellets using forest biomass and wood tar, which are manufactured by the above-described manufacturing method.
본 발명의 일실시예에 따르면, 바이오매스 연료와 석탄 연료의 혼소시 바이오매스의 혼소율을 높일 수 있다. According to one embodiment of the present invention, when co-firing biomass fuel and coal fuel, the co-firing rate of biomass can be increased.
그리고, 혼소율의 증가로 화석연료의 사용량을 감소시킬 수 있다. Additionally, the amount of fossil fuel usage can be reduced by increasing the co-firing rate.

실시예의 구성Configuration of the Example
이하, 첨부된 도면을 참조하여 바람직한 실시예의 구성을 상세히 설명하기로 한다. 도 1은 본 발명에 따른 마이크로웨이브를 이용한 산림바이오매스의 반탄화장치의 측면도이다. 본 발명에서, 미이용 산림바이오매스는 임목부산물(예 : 가지목 및 뿌리목 등)이 될 수 있다. Hereinafter, the configuration of the preferred embodiment will be described in detail with reference to the attached drawings. Figure 1 is a side view of a torrefaction device for forest biomass using microwaves according to the present invention. In the present invention, unused forest biomass can be forestry by-products (e.g., branch trees and root trees, etc.).
본 발명의 반탄화장치는 공지의 로터리킬른장치(100)에 적용될 수 있다. 투입부(110)는 일측에 구비되는 미이용 산림바이오매스가 투입되는 호퍼장치일 수 있다. The torrefaction device of the present invention can be applied to the known rotary kiln device 100. The input unit 110 may be a hopper device provided on one side into which unused forest biomass is input.
반응로(120)는 회전 가능한 원통 형상의 밀폐 구조이며, 내부가 진공 상태를 유지할 수 있다. 반응로(120) 내부의 산림바이오매스는 산소없이 고온으로 가열되어 열분해 반응을 일으킨다. 반응로(120)에서의 열분해시간은 10분 ~ 30분 범위이다. 최적의 생산효율과 반탄화 반응을 위해 10분 ~ 30분 범위에서 동작될 수 있으며, 바람직하게는 20분 ~ 30분이다. The reactor 120 has a rotatable cylindrical sealed structure, and its interior can maintain a vacuum state. The forest biomass inside the reactor 120 is heated to a high temperature without oxygen to cause a thermal decomposition reaction. The thermal decomposition time in the reactor 120 ranges from 10 minutes to 30 minutes. For optimal production efficiency and torrefaction reaction, it can be operated in the range of 10 to 30 minutes, preferably 20 to 30 minutes.
구동장치(130)는 원통형상의 반응로(120)를 일정한 속도로 회전시키거나 180° ~ 360° 범위에서 정역회전 시킬 수 있다. The driving device 130 can rotate the cylindrical reactor 120 at a constant speed or rotate it forward or backward in the range of 180° to 360°.
버너장치(140)는 반응로(120)의 둘레에 설치되어 반응로(120)를 최대 600℃까지 가열할 수 있다. 버너장치(140)는 가스버너 또는 기름버너가 될 수 있다. 본 발명의 실시예에서 반탄화를 위해 버너장치(140)는 200℃ ~ 250℃의 범위로 가열한다. 다수의 실험을 통해 200℃ ~ 250℃가 약 30분동안의 열분해 과정중 최적의 반탄화 반응을 일으키는 것으로 확인되었다. The burner device 140 is installed around the reactor 120 and can heat the reactor 120 up to 600°C. The burner device 140 may be a gas burner or an oil burner. For torrefaction in an embodiment of the present invention, the burner device 140 is heated in the range of 200°C to 250°C. Through numerous experiments, it was confirmed that 200℃ ~ 250℃ causes the optimal torrefaction reaction during the thermal decomposition process for about 30 minutes.
마이크로웨이브장치(150)는 반응로(120) 내면에 구비되어 반응로(120)와 함께 회전하며, 반응로(120) 내부를 향해 마이크로웨이브(160)를 방사한다. 마이크로웨이브(160)는 300 MHz ~ 300 GHz의 주파수 범위를 갖는다. 바람직하게는 2 ~ 3 GHz가 될 수 있고, 마이크로웨이브장치(150)는 마그네트론이 될 수 있고, 둘레에 단열처리가 된다. The microwave device 150 is provided on the inner surface of the reactor 120 and rotates with the reactor 120, and radiates microwaves 160 toward the inside of the reactor 120. Microwave 160 has a frequency range of 300 MHz to 300 GHz. Preferably, it can be 2 to 3 GHz, and the microwave device 150 can be a magnetron, and is insulated around it.
회전케이블(190)은 마이크로웨이브장치(150)와 교류 전원장치(180) 사이에 연결되어 마이크로웨이브장치(150)에 필요한 전력을 공급한다. 구동장치(130)가 180° ~ 360° 범위에서 정역회전하는 경우, 회전케이블(190)은 최소 반응로(120)의 원주길이에 대응되는 길이를 갖는 전기 배선이 될 수 있다. 반응로(120)의 회전에 방해되지 않으면 전력을 공급하기 충분한 길이면 족하다. The rotating cable 190 is connected between the microwave device 150 and the AC power supply 180 to supply the necessary power to the microwave device 150. When the driving device 130 rotates forward and backward in the range of 180° to 360°, the rotation cable 190 may be an electrical wire with a length corresponding to the minimum circumferential length of the reactor 120. Any length sufficient to supply power is sufficient as long as it does not interfere with the rotation of the reactor 120.
선택적으로, 구동장치(130)가 일정 속도로 회전하는 경우, 회전케이블(190)은 반응로(120)의 외곽 원주를 따라 설치된 슬립형 링전극이다. 공지의 슬립형 링전극을 통해 회전하는 반응로(120)의 내부로 전력을 공급할 수 있다. Optionally, when the driving device 130 rotates at a constant speed, the rotating cable 190 is a slip-type ring electrode installed along the outer circumference of the reactor 120. Power can be supplied to the inside of the rotating reactor 120 through a known slip-type ring electrode.
배출장치(170)는 마이크로웨이브(160)에 의해 반탄화된 산림바이오매스를 배출한다. 반탄화된 산림바이오매스는 펠릿 성형기에서 목재펠릿으로 성형된다. The discharge device 170 discharges forest biomass torrefied by the microwave 160. The torrefied forest biomass is formed into wood pellets in a pellet molding machine.
실시예의 동작Operation of the Embodiment
이하, 첨부된 도면을 참조하여 바람직한 실시예의 동작을 상세히 설명하기로 한다. 도 2는 본 발명의 일실시예에 따른 반탄화된 산림바이오매스와 목타르를 이용한 고품질 펠릿의 제조방법의 흐름도이다. 도 2에 도시된 바와 같이, 먼저, 미이용 산림바이오매스의 일부를 호퍼에 투입하고(S100), 나머지를 목분으로 가공한다. 미이용 산림바이오매스는 임목부산물(예 : 가지목 및 뿌리목 등)이 될 수 있고, 투입장치인 호퍼는 공지의 기계류이다. Hereinafter, the operation of the preferred embodiment will be described in detail with reference to the attached drawings. Figure 2 is a flow chart of a method for producing high-quality pellets using torrefied forest biomass and wood tar according to an embodiment of the present invention. As shown in Figure 2, first, part of the unused forest biomass is put into the hopper (S100), and the remainder is processed into wood flour. Unused forest biomass can be forestry by-products (e.g. branch trees and root trees, etc.), and the hopper, which is an input device, is a known piece of machinery.
마이크로웨이브(160)는 산림바이오매스의 내부 깊숙이 투과하면서 반탄화 반응을 일으킨다. 즉, 버너장치(140)에 의해 산림바이오매스의 겉면만 열분해되는 과정과는 상이하다. 본 발명의 일실시예에서는 산림바이오매스의 외면은 저온(200℃ ~ 250℃)에서 약 30분 동안 열분해 반응이 일어나고, 마이크로웨이브(160)에 의해 내부로부터 발열이 일어나며 이로 인해 반탄화 반응이 동시에 복합적으로 일어난다. The microwave 160 penetrates deep into the forest biomass and causes a torrefaction reaction. In other words, it is different from the process in which only the outer surface of forest biomass is pyrolyzed by the burner device 140. In one embodiment of the present invention, a thermal decomposition reaction occurs on the outer surface of the forest biomass for about 30 minutes at a low temperature (200 ° C. to 250 ° C.), and heat is generated from the inside by the microwave 160, which simultaneously causes a torrefaction reaction. It happens complexly.
그 다음, 로터리킬른장치(100)가 반탄화된 연료 및 부산물인 목타르를 각각 배출한다(S110, S120). 목타르는 미이용 바이오매스를 열분해로에서 열분해하는 경우 필연적으로 발생하는 부산물이다. 이러한 목타르는 흑색의 유상물질로 점성이 높고, 굳어서 딱딱해지는 특징이 있다. Next, the rotary kiln device 100 discharges the torrefied fuel and the wood tar as a by-product, respectively (S110, S120). Wood tar is a by-product that inevitably occurs when unused biomass is pyrolyzed in a pyrolysis furnace. This type of wood tar is a black oily substance with high viscosity and has the characteristic of becoming hard when hardened.
한편, 목분 가공단계(S100)는, 자력선별기가 산림바이오매스로부터 철조각을 선별한 뒤(S130), 분쇄기가 산림바이오매스를 소정입자 크기로 분쇄하여 목분을 생산한다(S140). 자력선별기는 3,000 ~ 5,000 가우스의 강자력을 갖는다. 분쇄기는 믹서 또는 그라인더, 블랜더 등이 될 수 있고, 생산된 목분은 1 mm ~ 8 mm 범위의 크기를 갖는다. Meanwhile, in the wood flour processing step (S100), a magnetic separator selects iron pieces from forest biomass (S130), and then a grinder crushes the forest biomass to a predetermined particle size to produce wood flour (S140). The magnetic separator has a strong magnetic force of 3,000 to 5,000 Gauss. The grinder can be a mixer, grinder, blender, etc., and the produced wood flour has a size ranging from 1 mm to 8 mm.
그 다음, 혼합장치가 목분, 반탄화 연료 및 목타르를 혼합한다(S160). 이때, 반탄화 연료 100중량부에 대해 3 ~ 20 중량부의 목타르; 및 90 ~ 120 중량부의 목분이 함께 투입된다. 3 중량부 미만의 목타르는 목분의 점착 성능을 기대하기 어렵고, 20 중량부를 초과하면 목타르의 점성으로 인해 재료의 이동과 성형성이 저하된다. 목분은 반탄화 연료와 동일하거나 비슷한 중량으로 투입한다. Next, the mixing device mixes wood flour, torrefied fuel, and wood tar (S160). At this time, 3 to 20 parts by weight of wood tar per 100 parts by weight of torrefied fuel; and 90 to 120 parts by weight of wood flour are added together. If the wood tar is less than 3 parts by weight, it is difficult to expect the adhesion performance of wood flour, and if it exceeds 20 parts by weight, the movement and formability of the material are reduced due to the viscosity of the wood tar. Wood flour is added in the same or similar weight to the torrefied fuel.
또한, 혼합단계(S160)에서, 혼합장치는 30℃ ~ 50℃로 예열된다. 혼합장치의 예열을 통해 목타르의 냉각을 방지할 수 있다. 예열을 위해 혼합장치에는 전열히터 또는 온수관이 배치될 수 있다. Additionally, in the mixing step (S160), the mixing device is preheated to 30°C to 50°C. Cooling of the wood tar can be prevented by preheating the mixing device. An electric heater or a hot water pipe may be placed in the mixing device for preheating.
그 다음, 성형기가 목분과 목타르의 혼합물로부터 고품질의 펠릿을 성형하여 완성한다(S170). 이 때, 완성된 펠릿은 원통 형상이며, 길이는 30mm ~ 50mm의 길이를 갖는다. 종래 펠릿의 길이가 20 mm 내외인 점을 감안할 때, 30mm ~ 50mm의 길이는 충분한 장신 펠릿이라고 할 수 있다. Next, the molding machine forms high-quality pellets from a mixture of wood flour and wood tar (S170). At this time, the completed pellet has a cylindrical shape and has a length of 30 mm to 50 mm. Considering that the length of conventional pellets is around 20 mm, a pellet with a length of 30 mm to 50 mm can be said to be sufficiently long.
비록 본 발명의 산림바이오매스는 미이용 산림바이오매스를 중심으로 설명하였으나, 초본계(볏짚, 옥수수대, 보리대, 밀대, 펄프, 야자나무잎 등) 또는 목질계, 그리고 초본계와 목질계가 혼합된 형태의 산림바이오매스도 가능하다.Although the forest biomass of the present invention was explained focusing on unused forest biomass, it is herbaceous (rice straw, corn stalks, barley stalks, wheat stalks, pulp, palm leaves, etc.) or woody type, and a mixture of herbaceous and woody types. Forest biomass is also possible.
