Ag-nox07 nox tail gas analyzer
Ag-nox07 nitrogen oxide tail gas analyzer is a high performance and fully functional analysis and treatment system for boiler flue gas environment, which integrates nitrogen oxide pretreatment, gas sampling, gas concentration analysis and networking module (optional).Based on the principle of electrochemistry, the monitor can quickly and accurately measure the concentration of nitrogen oxide, realize the real-time detection of nitrogen oxide concentration, and can store the emission monitoring data for more than one year.The system includes sampling system, pretreatment system, analysis system, temperature, humidity, flow rate, pressure measurement and other subsystems.
System composition:
(1) sampling probe
(2) heat tracing pipeline
(3) temperature pressure flow all-in-one machine (optional)
(4) pretreatment device (including cooling, dehumidification and filtration devices)
(5) nitrogen oxide gas analyzer
(6) O2 gas analyzer
(5) data acquisition and management software
(6) display and storage system
Scope of application:
The ag-nox07 nox tail gas analyzer is suitable for the monitoring of nox concentration in the tail gas of gas boilers under 20 tons of steam per hour, low nitrogen combustion retrofit boilers and low nitrogen burner, as well as the monitoring of nox in the tail gas of VOCs treatment project by combustion method.
Product features
Using imported electrochemical sensor, high precision, quick response, good repeatability;
The analysis process does not require chemical reagents, does not produce secondary pollution, is a non-destructive analysis process.
Three-stage pretreatment device: condensation, dust removal and drying
With the temperature and humidity compensation algorithm, effectively eliminate the temperature and humidity change interference
With nitric oxide, nitrogen dioxide, oxygen and other mutual interference compensation
Pump sampling is adopted, with zero point standard function to eliminate the drift of the system in long-term operation
