摘　　要：采用PF-300便携式甲烷、总烃、非甲烷总烃测试仪对烧结杯试验产生的烟气挥发性有机物含量进行分析,研究混合料水分、固体燃料质量分数和燃料种类对烧结烟气挥发性有机物释放的影响。研究结果表明:挥发性有机物在烧结过程中持续释放,在烧结过程的后1/3段其排放浓度明显降低;适宜的水分、较低的固体燃料消耗有利于降低挥发性有机物排放,同时,煤粉作为燃料时挥发性有机物排放明显比焦粉的挥发性有机物排放高且排放总质量与固体燃料的挥发分正相关,而非甲烷总烃的产生量不受燃料种类的影响,说明挥发分不是非甲烷总烃产生的决定性因素。The PF-300 portable total hydrocarbon tester to test methane(MHC),total hydrocarbon,non-methane(NMHC)was used to analyze the volatile organic content(VOC)of the flue gas generated in the sintering cup test.The effects of mixture moisture,solid fuel ratio and fuel type on volatile organic compounds release from sintering flue gas were studied.The results show that the volatile organic compounds are continuously released during the sintering process,and the emission concentration is significantly reduced in the last third of the sintering process.Suitable moisture and lower solid fuel consumption are beneficial to reduce volatile organic compounds emissions.The emission of volatile organic compounds in fuel is significantly higher than that of coke powder,and the total amount of emissions is positively correlated to the volatile content of solid fuels,while the amount of NMHC produced is not affected by the type of fuel,which indicates that volatile content is not the decisive factor for NMHC generation.
