Description

Product description
It is a explosion-proof tunable laser gas analyzer for slipping ammonia emissions monitoring for SCR or SNCR denitration apparatus. The analyzer is a field-mounted slipping ammonia on-line monitor based on TDLAS for NH3 trace analysis with the feature of low detection limit, accurate measurement results, easy calibration and alignment, simple and compact structure, no moving parts..

Features
1. Easy optical path adjusting, XY direction non-coupling adjusting.
2. Small drift, long maintenance period, drift ≤ 1%F.S./half year.
3. "Single line" spectrum technology, free from interference of background gas.
4. Integrated structure design, high stability and reliability.
5. Integrated flameproof structure, consuming less purge gas compared with positive-pressure mode.
6. In-situ measurement without pretreatment system avoids adsorption, blockage and damage, reduces cost.

Parameter
1. Installation method: in-situ, cross stack
2. Response time: ≤1s (T90)
3. Enclosure rating: IP66
4. I/O mode: 4-20mA, RS485/RS232/GPRS
5. Purge gas: 0.3MPa ~ 0.8MPa N2, clean air

Application
1. Slip ammonia emissions monitoring
2. Process control of SCR or SNCR DeNOx apparatus includes coal-fired power plants, aluminum, iron and steel plants, smelters, glass, garbage power plants, cement plants, chemical plants.
