CEMS-5000L Continuous Emission Monitoring System (Ultra-low Hot-wet) is developed based on UV differential absorption spectroscopy technique.
It is used for the online monitoring of SO2, NOx (NO, NO2) and atmospheric particulate in the ultra-low emission of various fixed sources, and can expand the monitoring of CO, CO2 and other pollutants.
The whole system is composed of four parts: * gaseous pollutant monitoring subsystem (O2, NOx (NO, NO2))
* atmospheric particulate monitoring subsystem,
* flue gas parameter monitoring subsystem (temperature, pressure, flow rate, humidity, oxygen content),
* system control and data collection and processing subsystem
Features* High integration, convenient maintenance.
The flue gas directly enters the analyzer after passing through the probe and the heat tracing pipeline with the sampling pump. Then the instrument will measure the gas concentration automatically.
* Multiple gases can be measured.
It can measure the CO2,N2O simultaneously. The result not been disturbed by the background gas. * High accuracy. Full-course high temperature heat companion.
The sample gas composition is stable, ensure the accuracy of the measurement value
* Low detection lower limit, fast response.
The system is developed based on advanced UV differential absorption spectroscopy techniques. Long light range,
high resolution. suitable for application in ultra-low field.
* Self-developed core modules and algorithms.
Effectively solves the error interference of spectral drift during the measurement.
independent measurement of NO and NO2, no need a nitrogen oxide converter
* Suitable for application in harsh environment, including high temperature,
high dust, and high humidity, high corrosion.
The sampling probe uses dust filtration technology and timing anti-blowing technology,
effectively prevent the probes from being easily blocked in harsh environment.
* Modular design, Easy customization.
Can be expanded with CO,CO2 test module, etc.
