摘　　要：介绍了焦炉燃烧废气含氧量检测系统,该系统分别对多个蓄热室小烟道处的燃烧废气取样,用1台氧化锆氧量分析仪检测燃烧废气的含氧量。在自动模式下,能在1个换向周期内完成多个下降气流的蓄热室含氧量的自动检测;在手动模式下,又能对单个蓄热室进行连续检测。系统检测精度高、实时性强、投资成本低、维护量少,为判断焦炉各燃烧室的燃烧状况提供了检测依据。The system for measuring oxygen content in coke oven burnt flue gas was introduced,this system can respectively take the samples of burnt flue gas from sole flues of several regenerators,and oxygen content in burnt flue gas was measured with one ZrO oxyen analyzer.In auto mode,automatic measurement of oxygen content in several downflue regenerators can be completed in one reversing cycle;In manual mode,the single regenerator can be continuously measured.The system is characterized by higher measuring accuracy,stronger real time ability,lower cost for investment and less maintenance,which has provided a measuring basis for judging the combustion condition of individual combustion chambers of coke oven.
