DTF를 이용한 석탄연소특성과 NOx 발생 및 저감에 관한 연구

Studies on Coal Combustion Characteristics and NOx Emission and Reduction in the Drop Tube Furnace

The objective of this study was to obtain basic data for the staged combustion toward the NOx reduction in coal combustion. Combustion and NOx emission/reduction were investigated by using DTF. NOx emission was decreased with decreasing air ratio and with increasing volatile content in coal. In particular, effective NOx reduction was achieved at high temperature at the onset of combustion with fuel rich condition.
