  • 본 연구는 국내 화장로 설비의 주류를 이루는 대차방식 화장로의 성능개선을 목표로 하였다. 주연소실 형상 변화를 통해 용적을 증대시키고, 버너연소제어 최적화를 통한 화장시간 단축 및 에너지 사용량 절감기술을 실증설비 기반으로 연구하였다. 1차적으로 열유동해석을 통해 최적화된 구조설계로 주연소실의 체적을 약 70% 증대시키므로 연소배가스의 체류시간이 증대되는 효과를 얻을 수 있었고, 이를 통해 설계한 파이로트 화장로를 제작하여 다양한 운전조건에서 연소거동을 실험하고 주연소실 형상별 최적의 운전방안을 도출하였다. 이렇게 도출된 결과를 반영하여 실증 화장로를 설계하고, P시 Y화장장에 설치하였다. 실증 화장로 조업을 통해 최적 연소조건을 도출할 수 있었고, 고온의 연소배가스의 체류시간 증대에 따른 에너지 효율의 증대효과로 기존대비 화장시간 및 연료사용량을 최소화할 수 있었다. 즉, 화장시간은 기존 화장로 조업대비 44.1% 단축된 38 min이었고, 연료사용량은 기존 화장로 대비 54.4% 절감된 $21.8Nm^3$이었다.

  • This paper focuses on prototype management models of location conflict concerned with crematory facilities in Korea. Using causal loops and stock-flow diagrams, it examines behavioral patterns of key variables, which would contribute to developing objective evaluation criteria. After a series of simulation works, the paper finds that the top priority should be given to how to improve neighboring residents' perception, ahead of specific compensation issues. Otherwise, they are open to vicious cycles or impasse. Juxtaposing individual cases together, Pusan and Cheongju examples which experienced the extreme confrontation in the initial stage could succeed in resolving crematory location conflict, especially between local residents and the public authorities, as the latter has repeatedly guaranteed to the former higher standards of participation. The opposite was almost true for Seoul and Ulsan cases, both of which were drawn into a crematory location whirlpool, incrementally losing resident's participation base. These results imply that the proposed management models would enhance mutual understanding among major stake-holders in relatively a shorter time, not to mention the overall cost.

  • 한국의 2016년 화장률은 82.7%로 1994년의 20.5%보다 4배나 높았다. 화장률이 점차 증가함에 따라 화장시설이 부족해지면서 화장률이 높아질수록 화장시설의 증설이 요구되고 있으며, 또한 화장로의 장기간 작동에 따라 많은 양의 연료가 사용되고 있다. 이러한 문제를 해결하기 위해 본 연구에서는 화장로의 열효율 특성을 최적화하고, 증가하는 화장에 대한 요구에 대응하는 화장 시스템을 제안한다. 본 논문의 목적은 전산 유체 역학(computational fluid dynamics, CFD)을 사용하여 시뮬레이션을 수행함으로써 열전달 계수를 포함한 열흐름 특성을 조사하는 것이다. CFD 모델은 화장시설에 대한 현장 실험으로 검증되었다. 시뮬레이션 결과, 주 연소기에서 연료 소비가 거의 25% 감소하고 체류 시간이 증가했다. 시뮬레이션을 토대로 개량된 연소기, 열교환기, 2차 연소 공기 시스템, 내화 및 단열재를 사용하여 개선된 화장로를 구성하였다. 현장실험 결과 에너지 소비가 약 54.4%로 줄어들었으며 연소 시간이 거의 20 min 단축되었다.

  • This study is to research the military remains of Korean War(1950~53) focused on Yeonchen, Cheorwon, and Hwacheon-gun in the central border of DMZ. The Yeoncheon-gun is installing 'Yeolsoe' and 'Taepung' observatory in the frontline battlefield adjacent to Southern Limit Line(SLL), and not only protects many military remains including war memorial and crematory facilities of UN troops, but also utilizes them as active educational places. The Cheorwon-gun is actively making known 'Baengmagoji memorial, 'Labor party office' and other buildings adjacent to 'Tourist security DMZ', but needs to set up many monuments around battlefields of 'Gimhwa' and 'Daeseongsan' adjacent to 'Eco-peace park DMZ'. With the battlefield of 'Paroho' as the center, which our troops made brilliant military gains during the war, the Hwacheon-gun protects and informs military remains such as '643 and 490 battlefields', 'Kkeomeok and Guman bridge'. Developing a network for military remains in connection with the annual local festivals, the experience tour and security will be available at these places.

  • The main purpose of this project is to improve the funeral and grave culture which has brought about many social problems, and to fix the crematory culture as the future funeral ceremony in our country. In this study, we first investigated the actual condition of cremation culture. Second, we survey three representative crematorium as an object of study and investigated similar sample buildings in Japan, we analyzed the problem of existing crematorium. Finally, we arranged the basics to approach the space program and design criteria of this project. 1. The entrance of vehicles has been commonly concentrated to the opening time of crematorium. therefore, Peak time has come out as circulation of cremation and waiting time is increasing, also it is difficult to manage the congestion normally. 2. The whole problem of crematorium is poor environment, inferior buildings, noise, unsatisfactory ventilation and privacy, insufficient convenience facilities. 3. The user demand on the crematorium facilities is a private family room for waiting area, a farewell room for family members in a direct line, an outdoor rest area, and the various service facilities, and so on. 4. For improvement of the funeral and grave culture, it is necessary that crematorium is not a hatred facilities, as the conversion of consciousness, and to new shape of charnel as it wore family tomb.

  • Recently, environmental issues have remained high on the agendas of public discussion and economic research. In the case of Korea, democratic movement in the late 80's centered people's concerns on the environmental dispute according to landfill, correctional institution, crematory, and nuclear powerplant, etc., Moreover, the failure to provide these kinds of facilities in time have caused serious social problems associated with environmental protection and economic development. The purposes of this paper are threefolds. First, they organize foreign and domestic NIMBYS case studies which have been settled in a desirable way. The second concern is to analyze the consciousness of NIMBYS resident by making up a questionnaire. Third, they estimate the market values of urban unwanted facilities by employing CVM(Contingent Valuation Method) procedure. The results of the study have a double implication : that NIMBYS resident are reluctant to accept government mechanical compensation based on simple published land values, and that unique concensus to preserve the viability and healthfulness of our environment among three main bodies: residents, people, government is necessary in solving NIMBYS subjects in Korea. In addition, this first implication develops to emphasize the intrduction of releveant measures taken to reconcile NIMBYS disagreement, which are complete openness of government policies, full support of local economic development, and perfect management of pollution protection systems for NIMBYS facilities.

  • Efficient simultaneous reduction conditions for $NO_x$ and $NH_3$-slip was investigated in SCR (Selective Catalytic Reduction) process with load variation by applying dual catalysts (SCR catalyst, $NH_3$ decomposition catalyst) system. $N_2O$ formation characteristics were analyzed to look into possible undesirable reaction pathways. In the experiments of catalyst characteristics, various operational variables were tested for the combined catalytic system, such as $NH_3/NO_x$ ratio, temperature, oxygen concentration and $H_2O$. The reaction characteristics of $NO_x$, $NH_3$ and $N_2O$ were analyzed and optimal conditions could be evaluated for the combustion facility with varied load. In terms of $NO_x/NH_3$ simultaneous reduction and $N_2O$ formation suppression, optimal condition was considered NSR 1.2 and temperature $300^{\circ}C$. At this operational condition, $NO_x$ conversion was 98%, $NH_3$ reduction efficiency was 95%, generated $N_2O$ concentration 9.5 ppm with inlet $NO_x$ concentration of 100 ppm. In $NH_3-SCR$ process with $NH_3$ decomposition catalyst, $NO_x$ and $NH_3$ can be considered to be reduced simultaneously at limited conditions. The results of this study may be utilized as basic data at facilities requiring simultaneous $NO_x$ and $NH_3$ reduction for facilities with load variation.
