III. Working Principle
The NOX concentration exceedance early warning system consists of four parts: the sampling system, pretreatment system, gas analysis system, and data collection and transmission system. The sampling system collects flue gas from boilers, filters it initially for dust, and then sends it to the pretreatment system. The pretreatment system cools, dehumidifies, and filters the gas for a second time. The gas analysis system performs concentration detection and analysis of the flue gas, with the analysis results displayed in real-time on the analyzer's screen. Additionally, these data are transmitted to PLCs, remote computers, or flue gas concentration monitoring cloud platforms via the internal networking module of the instrument.
