    TR-9300D Flue Gas Ultra-Low Emission Continuous Monitoring System
    Product Overview
       The TR-9300D Flue Gas Ultra-Low Emission Continuous Monitoring System is a state-of-the-art solution for ultra-low emission monitoring in coal-fired power plants. Designed to comply with HJ/T76-2007, HJ/T75-2007, and other national standards, it achieves emission concentrations close to gas-fired units: particulate matter ≤5 mg/m³, SO₂ ≤35 mg/m³, NOx ≤50 mg/m³ (at 6% O₂). This represents a 50%–30% reduction compared to GB13223-2011 special emission limits, establishing a new benchmark in clean coal power generation.
     
    System Function and Monitoring Principle
    Gas Pollutant Monitoring
       •Fully extracted sampling system draws flue gas via special ultra-low emission heated probes.
       •Gas passes through heated transfer lines, dedusting units, and ultra-low emission condensers to remove moisture.
       •Processed gas enters the JNYQ-S-81 flue gas analyzer, utilizing the DOAS (Differential Optical Absorption Spectroscopy) method.
       •DOAS principle: measures narrow-band absorption characteristics of target molecules, unaffected by water vapor or other interference gases, providing stable zero-drift measurements.
       •Data is transmitted to industrial PCs and data acquisition instruments for storage and remote transmission.
