A Study on Low Emission Pulverized Coal Combustion in the 2 Staged Coaxial Cyclone Combustor

2단 동축형 Cyclone 연소기를 이용한 저공해 미분탄 연소특성 연구

The objective of this study is development of low emission pulverized coal combustor for reducing pollutant emission generated from coal combustion. Low emission combustion technology for reducing NOx and fly ash was investigated by using 2 stage coaxial cyclone combustor. Staged combustion was employed for NOx reduction and high temperature slagging combustion was also studied for fly ash removal in the combustor. The result of this study shows that the low emission combustion system can reduce the amount of atmospheric pollutions with improved boiler efficiency and performance.
