SCR GA-5000DN Denox Ammonia Slip Monitoring Analyzer

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 dusting by sampling probe, sampling 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 unmeasurable. 

Technical Principle

Gas sample in flue passes through gas probe, primary filtration, sampling ball valve and secondary filtration in the chassis, then reaches to measuring cell. After analysis the density and humidity of all components, the sample gas will be drained through sampling pump.

By controlling sampling ball valve and back-blowing solenoid valve, the system can regularly back-blow to the probe. It can also realize the regular calibration of the analyzer by controlling sampling ball valve and calibration solenoid  valve.

Whole gas channel is with 150℃ high temperature heat tracing which completely avoids condensed water.

By adopting UV DOAS technology in analysis module, it effectively avoid the interference of dust and humidity.

Specification

Features

1. The measure lower limit of UV flue gas analyzer is as low as 1 mg/m3, and fully qualified for ultra-low emission monitoring measurement occasions;

2. The latest laser forward scattering dust monitor is suitable for high humidity flue gas, light-leaking stack and low dust emission and other application points.

3. Integration of low flow velocity of temperature pressure flow product solves the problem that normal product has inaccuracy measurement under low flue gas ;

4. By combining multistage dust filtration technology and regular blowing back, effectively prevent dust blocking filters and the pipeline, as well as polluting analyzer measurement pool. . It can adapt to the high dust, high humidity, high temperature, high corrosion resistance, etc.

5.Ultraviolet flue gas analyzer can simultaneously measure the SO2 , NO, NO2 (Being independent from NO), O2 , humidity , NOx can be obtained, by direct measuring of  NO and NO2 , without the converter of  NO2 - NO

6. Simple structure without optical moving parts, high reliability, long period free from maintenance, high resistance to vibration

7. Advanced uv difference spectrum technology adopted, spectrum holographic grating spectrometer, diode array detection, to obtain a complete continuous absorption spectrum, long takanami resolution to ensure low detection limit, small temperature drift, fast response time.
