Production, utilization and related regulation of refuse derived fuel in Korea have been discussed in this paper. Also, the expected future of RDF has been discussed. Although the interest about RDF has been increased continuously , there are many things that must be solved for the development of RDF industry. Compared with other developed country, inadequacy of regulation about RDF and the lack of possible utilization facility make the limitation for the development of RDF industry.

RDF(Refuse-Derived Fuel) is a fuel of pelletized form made of combustible solid wastes and can not only be used as alternative energy to fossil fuel but also solve troubles in thermal uses of incinerator. As the first stage for obtaining elementary data required to develop criteria of raw materials appropriate to RDF combustion facilities actively spread recently in Korea, preliminary experiments were conducted on CO, SOx, NOx and HCl production and reduction characteristics in combustion of RDF. RDF samples weighing 2~3 g per a sample were manufactured in a lab-scale way and combustion tests of RDF were carried out in electric furnace with quartz tube of 50 mm inside diameter.

Combustion of refuse derived fuel(RDF) and refuse plastic fuel (RPF) was carried out in a lab-scale circulating fluidized bed. Experiment was investigated cold flow visualization. RDF was made by C & tech and RPF was made by KRS. The results include distribution of temperature in the combustion chamber, and concentrations of flue gas such as $O_2$, $CO_2$, CO, $NO_x$ and HCs Micro G.C(gas chromatograph) was employed to find out concentration of He Temperature distribution was different when RDF and RPF were burnt respectably. As air ratio became increased, $CO_2$, CO, and total of HCs emissions were decreased. According to the number of carbon atom of HCs, HC were classified as five kinds of HC.

This paper deals with the result of an analysis on the effect of the power generation by municipal solid waste(MSW)-refuse derived fuel(RDF) and the introduction of tipping fee sharing between RDF manufacturing and power generation project. As a model case for the MSW generated at small and medium cities in our country, an analysis of the RDF power generation and Tipping fee sharing shows that 1) MSW amount of 7,800* $10^3 $t/y could produce 1,950*$10^3$t/y of RDF 2) Electric power generated by MSW-RDF could supply 290,000 households/year and 98,548 C-t/y of $CO_2$ could be reduced. 3) Tipping Fee should be shared by the considering of the contents of project of both side between RDF Production and power generation.

One of emerging technologies under development in the advanced countries is considered as RDF(Refuse Derived Fuel) power generation, which could meet both the requirement of an alternative energy resource utilization and $CO_2$ reduction. This paper deals with the effect to the thermal effiency and CO2 reduction of RDF firing power generation. The statistical data of domestic MSW generation in last year in small and medium cities for evaluating the merits of the RDF power generation were used. The analysis for RDF power generation compared to the existing incinerator w/o(or w/) power generation shows around 20.6%(10.0%) up in the total thermal efficiency and 57.0%(31.4%) up in the $CO_2$ reduction respectively.

폐기물 고형연료의 순환유동층 연소기술의 시범을 위하여 파일롯트 규모 순환유동층 연소보일러를 설계하고 건설하였다. 보일러의 규모는 출력기준 약 6 MWth에 해당하며 증기질은 $400^{\circ}C$, 38 ata로 설계하였다. 최대 증기출력은 약 8 ton/h에 해당한다. 연료는 RDF로 휘발분을 주성분으로 하며 점화가 빠르고 연소성이 매우 뛰어났으며 보일러의 연소효율은 99.5%를 능가하였다. 순환유동층 RDF 연소의 안정성은 연료중 회분 이외의 이물질의 존재 여부와 신속한 배출 가능성에 크게 의존하였다. 오염물질의 배출농도는 염소를 제외하고는 법적 기준치 이내에 들었다. 또한 60% 정도의 연료중 염소는 비산재에 흡수되는 것으로 나타났다. HCl을 국내 법 규제에 맞추어 제어하기 위해서는 건식 또는 습식 흡수 장치와 같은 별도의 환경설비가 필요하였다.

For resource Recycle society, the Ministry of Environment is recently propeling the introduction of MSW(Municipal Solid Waste) pretreatment facilities(MBT) from advanced country such as Germany. On the basis of this, The Ministry of Environment plans to expand all over the country after the adaption of wide area style(Sudokwon landfill : 200 ton/day), urban communities style(Bucheon City : 90 ton/day), Semi-urban(Gangreung City : 150 tons/a day), farm village style (Buan : 30 ton/day).

본 연구는 수거된 해양폐기물을 원료로 이용하여 폐기물연료(RDF : Refuse Derived Fuel)를 제조하는 공정 개발을 목적으로 하고 있으며, 산업용 연료로서의 활용 가능성을 확인하기 제조된 RDF의 물성분석을 분석하였다. 해양폐기물은 로우프에서의 납제거와 파쇄 그리고 해저 슬러지의 세척과 같은 전처리, 그리고 가연성분의 입자화 공정을 통하여 해양폐기물이 에너지로 변환하는 것이 가능하게 되었다. 이와 같은 해양폐기물 자원화 공정은 수거 폐기물의 환경적 처리는 물론 대체에너지 확보의 측면에서 매우 유익한 것으로 사료된다.

The electrochemical reaction of refuse derived fuel (RDF) and refuse plastic/paper fuel (RPF) was investigated in the direct carbon fuel cell (DCFC) system. The open circuit voltage (OCV) of RPF was higher than RDF and other coals because of its thermal reactive characteristic under carbon dioxide. The thermal reactivity of fuels was investigated by thermogravimetric analysis method. and the reaction rate of RPF was higher than other fuels. The behavior of all sample's potential was analogous in the beginning region of electrochemical reactions due to similar functional groups on the surface of fuels analyzed by X-ray Photoelectron Spectroscopy experiments. The potential level of RDF and RPF decreased rapidly comparing to coals in the next of the electrochemical reaction because the surface area and pore volume investigated by nitrogen gas adsorption tests were smaller than coals. This characteristic signifies the contact surface between electrolyte and fuel is restricted. The potential of fuels was maintained to the high current density region over 40 $mA/cm^2$ by total carbon component. The maximum power density of RDF and RPF reached up to 45~70% comparing to coal. The obvious improvement of maximum power density by increasing operating temperature was observed in both refuse fuels.

폐기물고형연료(RDF : Resused Derived Fuel)를 연료로 하는 연소기술의 개발을 위하여 기포유동층 연소로와 순환유동층 연소로, 연속연소식 연소로, 회분식 연소로 등 다양한 연소장치를 이용하여 연소 특성실험을 하였다. 여러 종류의 연소설비에서 RDF의 연소 및 배출가스 특성을 비교, 분석하였으며 RDF 전용 연소설비에 대하여 보다 깊은 연구의 기초 자료로 활용하자고 하였다. 기포 유동층 및 순환유동층연소로에서는 적정투입량과 가스공탑속도등 적정운전조건에 따라 안정적인 연소가 이루어지는 것을 확인할 수 있었다. 순환유동층 연소로에서 연소조건에 따라 연료 중의 질소성분과 연소공기 중의 산소와의 반응이 커져서 NOx의 농도가 높아지는 것을 알 수 있었으며 $SO_2$는 매우 낮은 농도로 측정되어 RDF의 유동층 연소시 거의 발생하지 않는 것으로 판단되었으며, HCl의 경우 평균 36.4ppm으로 배출허용기준치보다는 낮으나 저감대책이 필요한 것으로 판단되었다. 연속연소식 연소로와 회분식 연소로의 경우 성형 RDF와 fluff RDF를 비교 실험한 결과 높은 밀도를 가진 성형 RDF의 연소가 안정적인 열회수 측면에서 더 유리한 것을 알 수 있었으며 배가스 특성은 비슷한 값을 나타내었으며 배출가스 특성은 비슷하였다.
