Cold Drying Method SO2 NO NO2 Online Continuous Emission Monitoring CEMS System Online Gas Analyzer

This system monitors real-time concentrations of particulate matter and gaseous pollutants in flue gas emitted from stationary pollution sources such as boilers, industrial furnaces, incinerators, and similar equipment. It enables comprehensive supervision of production processes and emissions directly from the source.

The Continuous Emission Monitoring System (CEMS) consists of three fundamental components:

• Gaseous pollutant monitoring unit (SO2, NO, NO2)
• Flue gas parameter monitoring unit (temperature, pressure, flow rate, O2, humidity)
• Data acquisition and processing unit

The sample gas flows through a high-temperature heated pipeline, undergoes dust removal via a two-stage filter system, and is dehumidified by a two-stage condensation system before entering the analyzer's gas chamber. The gas chamber connects to an ultraviolet differential analyzer through ultraviolet optical fibers, ensuring precise measurement of flue gas components.

• Secondary condensation system for rapid water removal, minimizing SO2 loss
• Long-life UV xenon lamp with high wavelength resolution ensures low detection limits, minimal temperature drift, fast response time, and accurate measurements
• PLC-controlled system with adjustable parameters to adapt to complex working conditions
• Intelligent system design with traceable fault alarms for simplified maintenance and troubleshooting
• Fully modular design enabling flexible expansion of monitoring factors
• Flexible configuration options: Users can select between NO2-NO converter or direct NO measurement based on requirements
