摘　　要：为研究平板玻璃行业玻璃熔窑大气污染物排放特性,利用便携式红外烟气分析仪、可过滤和可凝结颗粒物采样器等监测设备,开展玻璃熔窑废气监测。结果表明生产原料、燃料、废气处理工艺等因素对污染物的排放影响明显。监测的4个玻璃熔窑废气中,3个熔窑废气CPM在总颗粒物中占比较高,使用有机物含量较高的蒽油及煤焦油混合燃料,CPM排放浓度远高于石油焦和天然气作燃料的玻璃熔窑废气,玻璃熔窑排放量大的污染物主要有SO_(2)、NO_(X)、CO等气态污染物和SO_(4)^(2-)、NH_(4)^(+)、Cl^(-)、Na^(+)、Ca^(2+)、NO_(3)^(-)等水溶性离子,排放浓度相对较高的金属元素有Fe、Al、Zn、Ba、Ti、Pb等。To study the emission characteristics of air pollutants from glass furnaces of the flat glass industry,portable infrared flue gas analyzer,filterable and condensable particle sampler and other monitoring equipment are used to monitor the waste gas of glass furnaces.The results showed that the production raw materials,fuels and waste gas treatment process had obvious effects on the emission of pollutants.Among the four monitored glass furnace exhaust gases,three furnace exhaust gases have a relatively high proportion of CPM to total particulate matters.If the mixed fuel of anthracene oil and coal tar with high organic content is used,the emission concentration of CPM is much higher than that of the exhaust gas from glass furnaces fueled by petroleum coke and natural gas.The pollutants with large emission from glass furnace mainly include gaseous pollutants such as SO_(2),NO_(X) and CO and water⁃soluble ions such as SO_(4)^(2-),NH_(4)^(+),Cl^(-),Na^(+),Ca^(2+),NO_(3)^(-),and the metal elements with relatively high emission concentration include Fe,Al,Zn,Ba,Ti,Pb,etc.
