GA-5000DN DeNOx Ammonia Slip Online Monitoring System

GA-5000DN DeNOx Ammonia Slip Online Monitoring System

Overview

GA-5000DN is based on a tunable semiconductor laser absorption spectroscopy (TDLAS) technology principle, including three parts: pretreatment, gas analysis module and data processing and display. After dedusting by sampling probe, tracing by heating pipe, the measured gas is analyzed by the hot gas analysis module (TDLAS technique). It is an effective solution to the technical problem that ammonium salt crystallization plugs flow at low temperature, and that absorption of NH3 by condensation water leads to low measurement precision and that in situ system high dust attenuation light path leads to immeasurable.

Feature Of GA-5000DN DeNOx Ammonia Slip Online Monitoring System


  • Single line spectrum technology avoid interference of background gas absorption, low detection limit, small scale drift;
  • More than 220 ℃ heat tracing avoid ammonium salt crystallization and moisture dissolve and absorption;
  • A high degree of automation, a small amount of maintenance;
  • Compact structure, easy to install.

Application Of GA-5000DN DeNOx Ammonia Slip Online Monitoring System


Apply to the ammonia slip emission monitoring and process control of SCR or SNCR deNOx device such as coal-fired power plant, aluminum plant, steel mills, smelting, glass factory, garbage power plant, cement plant, chemical plant, etc.
