    CEMS烟气在线分析仪用于测量烟气中的SO2/NOX/O2/粉尘/温压流/湿度等参数的便携式仪器,是一种测量工业加热炉烟气排放的理想仪器,结构紧凑的多功能仪器,一台仪器就能满足所有重要参数的测量和对气体干燥的要求。仪器和附件很轻,一个人就能携带和操作。它的体积很小,能够很容易地放入难进入的地方,可根据现场工况和技术要求进行灵活优化的配置,充分满足用户的需求,节省你的时间和金钱。

    CEMS是英文Continuous Emission Monitoring System的缩写,是指对大气污染源排放的气态污染物和颗粒物进行浓度和排放总量连续监测并将信息实时传输到主管部门的装置,被称为“烟气自动监控系统”,CEMS分别由气态污染物监测子系统、颗粒物监测子系统、烟气参数监测子系统和数据采集处理与通讯子系统组成。气态污染物监测子系统主要用于监测气态污染物SO2、NOx等的浓度和排放总量;颗粒物监测子系统主要用来监测烟尘的浓度和排放总量;烟气参数监测子系统主要用来测量烟气流速、烟气温度、烟气压力、烟气含氧量、烟气湿度等,用于排放总量的积算和相关浓度的折算;数据采集处理与通讯子系统由数据采集器和计算机系统构成,实时采集各项参数,生成各浓度值对应的干基、湿基及折算浓度,生成日、月、年的累积排放量,完成丢失数据的补偿并将报表实时传输到主管部门。烟尘测试由跨烟道不透明度测尘仪、β射线测尘仪发展到插入式向后散射红外光或激光测尘仪以及前散射、侧散射、电量测尘仪等。根据取样方式不同,CEMS主要可分为直接测量、抽取式测量和遥感测量3种技术。

    CEMS Flue Gas On-line Analyzer is a portable instrument for measuring parameters such as SO2/NOX/O2/dust/warm pressure/humidity in flue gas. It is an ideal instrument for measuring flue gas emissions from industrial furnaces. Functional instrumentation, one instrument can meet the measurement of all important parameters and the requirements for gas drying. The instruments and accessories are light and can be carried and operated by one person. It is small in size and can be easily placed in difficult to access places. It can be flexibly optimized according to site conditions and technical requirements to fully meet the needs of users and save you time and money.
    CEMS is the abbreviation of English Continuous Emission Monitoring System. It refers to the device that continuously monitors the concentration and emission of gaseous pollutants and particulate matter emitted by atmospheric pollution sources and transmits the information to the competent department in real time. It is called “automatic monitoring of flue gas”. System", CEMS consists of gas pollutant monitoring subsystem, particulate matter monitoring subsystem, flue gas parameter monitoring subsystem and data acquisition processing and communication subsystem. The gaseous pollutant monitoring subsystem is mainly used to monitor the concentration and total amount of gaseous pollutants SO2, NOx, etc.; the particulate matter monitoring subsystem is mainly used to monitor the concentration of smoke and the total amount of emissions; the flue gas parameter monitoring subsystem is mainly used to measure Flue gas flow rate, flue gas temperature, flue gas pressure, flue gas oxygen content, flue gas humidity, etc., used for the calculation of total discharge and related concentration conversion; data acquisition and processing and communication subsystem by data collector and computer The system consists of real-time collecting various parameters, generating the dry basis, wet basis and conversion concentration corresponding to each concentration value, generating the cumulative emissions of the day, month and year, completing the compensation of the lost data and transmitting the report to the competent department in real time. The soot test is developed from a trans-flue opacity dust meter, a beta ray dust meter to a plug-in backscattered infrared light or laser dust meter, as well as a front scatter, side scatter, and a power dust meter. According to different sampling methods, CEMS can be divided into direct measurement, removable measurement and remote sensing measurement.
