| 摘 要： | 在水平管式炉上研究了O2浓度、CO2浓度、温度及石灰石添加等各参数对O2/CO2气氛下徐州烟煤和龙岩无烟煤燃烧过程中SO2/NO排放特性的影响。结果发现，O2/CO2气氛下，烟煤和无烟煤燃烧SO2/NO的析出规律与空气气氛下不同，同等O2浓度下析出量比空气气氛下小。O2/CO2气氛下，随着O2浓度的提高，烟煤和无烟煤SO2/NO排放量均增大;随着CO2浓度的升高， SO2/NO排放量均减小。O2/CO2气氛下，石灰石添加对SO2排放的抑制作用低于空气气氛下;石灰石添加对NO的排放有一定减排作用。对煤灰的元素分析显示O2/CO2燃烧对SO2的抑制主要是由于煤灰的自固硫能力增强，而对NO的减排作用则是促进燃料N向其他含N气体的转换。

| Abstract: | The effects of O2 concentration,CO2 concentration,temperature and limestone addition on SO2/NO emission characteristics from Xuzhou bituminous coal and Longyan anthracite coal combustion in O2/CO2 atmosphere were studied in a horizontal tube furnace.The results showed that the release characteristics of SO2 /NO were different between O2/CO2 combustion and air combustion,and with the same O2 concentration,SO2 and NO emissions were lower in O2/CO2 combustion than those in air combustion.As O2 concentration in... |
