  • This paper investigates the dehydration and RDF (Refuse Derived Fuel) production of organic wastes, livestock manure and sewerage sludge with pressurized hydrothermal treatment process. The renewable technology for the organic wastes must involve short treatment time required, reusable energy source, anti-odor and viruses, low cost for the treatment, and well-fertilization. The pressurized hydrothermal treatment process promotes to evaporate moisture in the waste after being shortly treated in a reactor, which uses steam and heat supplied by an external boiler. By the pressurized steam, the cell walls of the waste break and effectively release the internal moisture. Then, the dried waste can be mixed with waste vinyls to produce RDF with a higher heating value as high as 6,700 kcal/kg.

  • 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.

  • 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.

  • RDF 생산 기술은 국내 실정에 맞는 제조 설비로 자체 생산할 수 있는 단계이지만, 사업장 가연성 폐기물에 대한 연료화 설비가 구축된 사례는 드물다. 본 연구에서는 사업장 가연성 폐기물을 대상으로 한 RPF(Refuse Plastic Fuel) 제조 공정의 고형연료 제조 가능성에 대해 검토하였다. 고형연료는 폐합성수지, 폐지 및 폐목재의 지역별 폐기물 발생비율 기준으로 제조되었으며, 제조된 RPF의 물리적 특성을 조사하였다. 대경(대구, 경북)지역을 기준으로 제조된 RPF의 발열량이 가장 높게 나타났으며, 폐지와 폐목재의 첨가량이 늘어날수록 발열량은 감소하였다.

  • In order to provide fundamental data for developing high-grade(high-quality and low-pollution) Refuse Derived Fuel(RDF), we analyzed caloric value and HCl content by Municipal Solid Waste(MSW) type. The caloric value was analyzed using calorimeter and HCl content was analyzed using mercury(II) thiocyanate method. In case of paper type the caloric value was 3,060~3,608kcal/kg and the HCl content was 239~6,135ppm. In case of vinyl-plastics the caloric value was 5,946~9,888kcal/kg and the HCl content was 429~455,771ppm. According to the result of quality assessment by MSW type, the calroric value of vinyl-plastics type was showed higher than that of paper type and in case of HCl content the paper type was showed lower than vinyl-plastics type. So, We mixed paper and plastic wastes. The caloric value of mixed MSW(paper and plastics) was 5,046~9,125kcal/kg and the HCl content was 239~6,135ppm. Also, The caloric value of packaging waste(film-plastics) was 5,982~8,045kcal/kg. Therefore It is possible to develop high-grade Refuse Derived Fuel through suitable mixing of paper and plastic in municipal solid waste.

  • The co-combustion of coal and three kinds of RDFs(Refuse Plastic Fuel) mixture has been experimented in a commercially operating CFB coal boiler respectively and the pollutant emissions such as SOx, NOx, TSP and dioxine were measured at the stack. The mixing ratio with coal was 7.5% RPF, 7.5% RDF and 10% SDF respectively. During co-combustion, dioxine emission level was very low and SOx, NOx and TSP were decreased comparing the single coal combustion. Emitting dioxine concentration was proportioned to the chlorine content of RDF. These RPF, SDF and RDF could be determined to be a good alternative fuel of general coal.

  • 본 연구는 B시 생활폐기물 및 유기성 폐기물의 혼합에 따른 연료화 및 활용방안에 대한 연구를 진행하였다. 반입폐기물, sludge cake와 food wast의 모든 혼합비율의 발열량이 6,000 kcal/kg으로 산출되었고, sludge의 경우 공연비와 온도가 높을수록 발생되는 유해물질 농도가 낮은 것으로 나타났다. 유해물질의 배출기준과 비교하여 보았을 때, 공연비가 2인 경우 800$^{\circ}C$일 때 유해물질 (CO, NOx, SOx)들이 기준이하의 배출 농도를 나타내었으며 혼재 소각 시 소각로 내부 온도 또한 가장 안정되는 것으로 나타났다. 소각시 완전연소가 이루어진다면, 혼합하여 RDF를 제조 시 발열량이 6000 kcal/kg이상으로 연료화 하기에 적합한 것으로 나타났다.
