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 more. It enables comprehensive supervision of production and emissions directly from the source.
The CEMS (Continuous Emission Monitoring System) consists of three fundamental components: the gaseous pollutant monitoring unit (SO2, NO, NO2), the flue gas parameter monitoring unit (temperature, pressure, flow rate, O2, humidity), and the data acquisition and processing unit.
Sample gas passes through a high-temperature heated pipeline, undergoes dust removal via a two-stage filter, and is dehumidified by a two-stage condensation system before directly entering the gas chamber of the analyzer. The gas chamber is housed within the analyzer and connected to an ultraviolet differential analyzer via ultraviolet optical fibers, ensuring accurate measurement of flue gas components.
