DTF 내 미분탄의 분산이 연소에 미치는 영향과 이를 고려한 순산소 연소특성 연구 = Effects of Pulverized Coal Dispersion in DTF on Its Combustion and Oxy-PC Combustion Characteristics Considering It

다국어 초록 (Multilingual Abstract)

An experimental study was conducted about the effects of pulverized coal dispersion in DTF on its combustion characteristics. Since the temporal steadiness and spacial uniformity of coal feeding are the prerequisites in DTF experiments and the lack of these conditions can give erroneous results, we tried to make our facilities satisfying them. Coal feeding tests with high resolution balances and visualization of coal particles falling in nonreactive drop tube were conducted and the obtained quantitative and qualitative results confirmed what our designs of feeding devices make reliable dispersion of coal particles in time and space. Based on these results, we inspected the effects of coal dispersion on its combustion characteristics in DTF and it were found that the coal combustion is very sensitive on that. Additionally it was tried to obtain several data on oxygen combustion of coal and high concentration CO₂ over 95% could be easily captured.
