详细说明:


Instructions:


Wr-4000dn denitrifying ammonia escape online monitoring system (NH3) is based on the principle of tunable semiconductor laser absorption spectroscopy (TDLAS). The system includes pretreatment, gas analysis module and data processing and display. The measured gas is dedusted by the high temperature sampling probe, transmitted by the heat pipe at high temperature, and entered the high temperature gas analysis module (TDLAS technology) for analysis and measurement. Effectively solve the ammonium salt crystallization at low temperature plug flow, low temperature condensate precipitate dissolve NH3 measurement accuracy is low, in situ system caused by high attenuation light path leading to dust and other technical problems can't be measured.

The characteristics of

Single-line absorption technology can avoid background gas interference, low detection limit and small range drift

More than 220 ℃ heat tracing avoid ammonium salt crystallization and dissolve moisture absorption

High degree of automation, small maintenance

Compact and easy to install

application

Applicable to the coal-fired power plant, aluminium plant, steel mills, smelting, glass factory, garbage power plant, cement plant, chemical plant and so on SCR or SNCR denitration device of ammonia escape emission monitoring and process control
