I. Product Introduction
The Ammonia Slip Online Monitoring System (Model TR-9300N) is proudly produced by Xi'an Juneng Instrument Co., Ltd. It is developed to prevent financial waste and environmental pollution caused by escaped ammonia. Ammonia slip will corrode the catalyst module, leading to catalyst deactivation (i.e., failure) and blockage, significantly shortening the catalyst's lifespan. Escaped ammonia can react with SO? in the air to form ammonium sulfate salts (which are corrosive and adhesive), causing blockage and corrosion of the air preheater's heat storage elements located downstream of the denitrification system. Excessive ammonia slip can be absorbed by fly ash, resulting in the inability to sell aerated blocks (ash bricks). For details, please contact: Jia Weihao

II. System Advantages
Due to harsh working conditions, the sample gas contains a large amount of dust and saturated water vapor. We use the advanced TR-9300N laser gas analyzer (based on TDLAS technology) to analyze trace amounts of NH?. The system (including the measurement cell) employs full-process heating to maintain the sample gas temperature, preventing water condensation and the significant dissolution of NH?, which could affect the analysis results. The probe uses an electrically heated filtering probe to purify the sample immediately upon extraction, reducing the load on subsequent pretreatment stages and significantly lowering the failure rate of components. The system is designed with an automatic probe blowback program and an automatic instrument zero-calibration program, requiring only routine inspection during normal operation. The transmission pipeline uses custom high-temperature composite electric heat-traced tubing rated above 230°C and is controlled within 2 meters (to minimize NH? adsorption). The entire pretreatment process is integrated into a high-temperature heating box, making the system compact to avoid NH? adsorption in long-distance transmission lines.

III. System Features
The Ammonia Slip Online Monitoring System primarily offers the following technical advantages:
Reliable long optical path heated gas cell design, with an optical path of up to 3 meters
Ultra-low concentration measurement, with a resolution of up to 0.1 ppm
Special multi-line spectral scanning algorithm with dynamic compensation for dust and moisture interference
Calibration-free design, simple maintenance, and low operating costs
The sampling probe, used for sample gas extraction in this system, features dust filtration and heat tracing functions, effectively preventing condensation of the collected sample gas. Its unique structural design ensures greater reliability of the sampling system, minimizes sample gas loss, and guarantees the stability and accuracy of the analysis system.
