“…Solid line), which were proportional to the aforementioned decrease in O 2 concentration level. In previous studies, it was reported that the inverse proportion of CO 2 generation level and O 2 concentration level increased the rate of complete combustion (Choi et al, 2015). Looking at the trend with ventilation, in the case of A1, A3, B1, and B2…”

“…실선), 앞서 언급한 O 2 농도의 감소량과 비례하는 결과를 보였다. 선행 연구에서도 CO 2 발생량과 O 2 농도의 반비례는 완전연소의 비율을 증가시킨다고 보고되었다 (Choi et al, 2015). 환기 조건의 경향을 살펴보면 특정 시점(10분)에 CO 2 발생량이 약 1.5% 이상인 A1, A3, B1, B2의 경우 환기팬 가동 후 최대 44.1%, 50.0%, 51.3%, 53.6%의 환기율을 보였다 (Fig.…”

This study was conducted into combustion characteristics and gases generated by the combustion of charcoal and agglomerated charcoal distributed in the domestic using a combustion chamber based on the average space per crater of a charcoal-grilled restaurant in South Korea. Each of the three types of charcoals and agglomerated wood charcoals was analyzed for fuel and combustion characteristics. In addition, the concentration changes of CO, CO 2 , NO x , and O 2 were measured for 20 minutes depending on ventilation. As a result, CO yield without ventilation was measured in the range of 1390 to 4703 ppm, and CO yield with ventilation decreases about 29.8% to 57.4%. CO 2 yield without ventilation was measured in the range of 1.34% to 2.42%, and CO 2 yield was about 44.1% to 53.6% when the emission was more than about 1.5% at 10 minutes. The NOx yield was divided into two cases where the NO x yield was continuously increased because of incomplete combustion, emitted ranging from 29 ppm to 47 ppm, and where emission was constant after 1 minute in the range of 9 ppm to 18 ppm. The NO x yield with ventilation tends to be similar to the without ventilation, and NO x yield decreases up to 62.5%. Therefore, it could be used for health risk assessment with the simulation of the usage environment of charcoal and agglomerated wood charcoal.
