A study on waste heat utilization of melted slags at pyorlysis, gasification and melting system was performed. Researchers studied heat balance of substances that flow and flow out to the system which is consisted of melting furnace, combustion chamber, and waste heat boiler, then they calculated melting slags' quantity of heat by the first law of thermodynamics. If they use water cursh pit outflow which is gotten by quenching of melting slag as a energy for heating and cooling system, steam of waste heat boiler would be delivered to a steam turbine, making energy, then they will get 67,671,000 won of profit a year. It will take 3 years to repossess the cost that they invested for building it. And, if we predict durability of trash burner is 20 years, we will get approximately 1,150,407,000 won of profits in 17 years without the period when we repossess the building costs.

The incineration process has commonly used for wastes amount reduction and thermal treatments of pollutants as the technologies accumulated. However, the process is getting negative public images owing to matter of hazardous pollutants emission. Specially dioxins became a main issue and were mostly emitted from municipal solid wastes incineration. In this reason, pyrolysis/gasification/melting process is presented as an alternative of incineration process. The pyrolysis/gasification/melting process, a novel technology, is middle of verification of commercial plant and development of technologies in Korea. But the survey about the pollutant emission from the process, and background data in these facilities is necessary. So in this survey, t is investigated that the behavior of chlorobenzenes and chlorophenols in plasma type pyrolysis/gasification/melting plant of pilot scale. We investigated discharging behavior of each phase of chlorobenzene through each process in the plsasma type pyrolysis/gasification/melting process. From this result, it was found that about 99 percent of particle-phase chlorobenzene was removed, but on the other hand gas-phase chlorobenzene was increased by about 600 percent through heat exchanger, flue gas cooling, system and semi dry absorption bag filter(SDA/BF). Also, this investigation presented that di-chlorobenzene(DCB) tri-chlorobenzene(TCB), tetra-chlorobenzene(TeCB), penta-chlorobenzene (PCB), except mono-chlorobenzene(MCB) and hexa-chlorobenzene(HCB) were increased through the flue gas cooling system and the semi dry absorption bag filter(SDA/BF). It was investigated that concentration of particle-phase chlorophenol was decreased by about 66 percent, but on the other hand, concentration of gas-phase chlorophenol was increased by about 170 percent through heat exchanger, flue gas cooling system, and semi dry absorption bag filter(SDA/BF). Also, it was found that di-chlorophenol(DCP), tri-chlorophenol(TCP), and penta-chlorophenol(PCP) were increased through the flue gas cooling system, and the semi dry absorption bag filter(SDA/BF). It can be considered that small-scale pilot facility and short investigation period might cause the concentration increase through the flue gas cooling system and the semi dry absorption bag filter(SDA/BF). A further study on real-scale pilot facility and accurate investigation may be required.

저공해 소각 시스템이 구성되어 현재 폐기물처리의 주축을 이루고 있으나 경제 발전과 환경에 대한 인식, 재활용을 위한 분리수거율 향상 등으로 인하여 폐기물의 발열량이 점차 증가되고 있는 실정이다. 따라서 높은 발열량을 이용한 에너지의 효율적 이용에 대한 요구와 소각로에서 필수적으로 수반되는 중금속 ash문제, dioxin의 저감문제 등을 보다 효과적으로 처리하는 방법에 대한 연구가 끊임없이 지속되어 왔다. 여기에서는 최근에 가장 현실적으로 접근되고 있는 열분해시스템, 열분해용융시스템, 열분해가스화용융시스템의 대표적인 설비에 관하여 기술하였다.

폐기물이란 쓰레기ㆍ연소재ㆍ오니ㆍ폐유ㆍ폐산ㆍ폐알칼리 등 사람의 생활이나 사업활동에 필요 없게 된 물질을 말하는 것으로, 쓰레기와는 엄밀한 의미로는 구분되지만 일반적으로는 버리는 것은 모두 폐기물이라고 볼 수 있다. 폐기물은 발생 주체에 따라 생활폐기물과 사업장폐기물로 구분되는데, 사업장폐기물은 사업장에서 발생되는 폐기물로 구성물질은 업종과 생산공정에 따라 다양하다.(중략)
