Zetian - Model GA-5000GI -On-site Continuous Emission Monitoring System（TDLAS)
Waste incineration plant shall automatically and continuously monitor the content of main components in the incineration flue gas, including CO, HF, HCl, SO2, NOX, flue gas, etc. Among them, HCl and HF are the difficulties of detection. Under this working condition, our company has launched the HCl/HF analysis system for waste incineration. Based on the principle of TDLAS, this system adopts Multi-channel Reflection Technology to increase the measuring optical path, and simultaneously measures HCl and HF by in-situ high temperature heat wet extraction method.Extraction with whole-process high-temperature (above 120℃) tracing, avoiding HCl/HF dissolving in water and form sour corrosion;
On-site installation, avoiding the absorption of HCl and HF gas in the pipeline as much as possible to improve measurement accuracy;
Advanced online HCl and HF analysis technology: “TDLAS + Multi-channel reflection technology”;
No moving parts, powerful functions, support auto calibration, remote operation and maintenance, remote software upgrade, etc.
Suitable for various environmental protection and industrial process gas emission monitoring, mainly used for flue gas analysis in waste incineration plants
