초록

본 연구에서는 졸참나무를 반탄화 처리 후 성형숯 형태로 제작하여 물성과 연료특성 및 연소과정에서 발생되는 유해가스 정량분석을 수행하였다. 또한, 대조군으로 시중에서 유통 중인 구이용 성형숯을 선정하여 비교분석하였다. 그 결과, 반탄화 시험편의 고위발열량은 구이용 성형숯 보다 약 14% 높았으며, 회분함량은 약 51배 낮았다. 또한, 밀폐된 챔버에서 각각의 시험편을 900 s간 연소시켰을 때 발생되는 유해가스(일산화탄소, 질산화합물, 이산화황)를 정량평가한 결과, 반탄화 시험편에서 발생한 일산화탄소의 발생량의 최대값이 기존 성형숯보다 약 50배 낮은 것으로 확인되었다. 따라서, 본 연구에서 제작한 반탄화 시험편이 시중 성형숯보다 고위발열량이 높고 연소과정에서 일산화탄소 발생량이 현저히 적은 것으로 나타났다.

In this study, a torrefaction of Quercus serrata to manufacture a molded charcoal was performed, investigated material properties, fuel characteristics, and performed a quantitative analysis of hazardous gases which occur during a combustion process. In addition, a molded charcoal in market was selected as a control group, and a comparative analysis was performed. As a result, the higher heating value (HHV) of the torrefied specimen was about 14% higher than that of molded charcoal, and its ash content was about 51 times lower. Moreover, after performing a quantitative assessment of hazardous gases (carbon monoxide, nitrogen oxide, and sulfur dioxide) which were produced when each specimen was combusted for 900 seconds in an enclosed chamber, it was confirmed that the maximum value of generated amount of carbon monoxide on the torrefied specimen was about 50 times lower than that of the existing molded charcoal. Therefore, it was shown that the torrefied specimen produced in this study had a higher heating value than the molded charcoal in the market, and a very low amount of carbon monoxide generated during the combustion process.
