Waste Incineration Cems Flue Gas HCl Co Continuous Emission Monitoring System
1. Basic Design Principle of WT-400 Analysis System
The WT-400 Ammonia Analysis System is a high-temperature extractive monitoring system, with a laser NH₃ analyzer as the core analysis unit. All parts in contact with the sample gas are heated and insulated above 180℃ throughout the process, ensuring accurate and stable NH₃ measurement.
