Abstract
This paper selects absorption line near 2.25μm, and has temperature correction test range 20〜270℃, this allows more accurate measurement results. It makes relative error from 67.53% to 3.33% at 200℃. Design and install measuring gun, and realize continuous on-line measurement of SCR process ammonia slip of a power unit of Jiaxing Jies Power Plant, the measurement results basically reflect the real-time ammonia slip rate of this power unit. It lays the foundation for future power plant continuous on-line measurement technology for the escaping ammonia of SCR process.
