PICO PLGT-450 Flue Gas Analyzer

Instrument Introduction :

PLGT-450 Flue Gas Analyzer is a highly integrated single-flange gas monitoring equipment, of which, core detection module adopts Tunable Diode Laser Absorption Spectroscopy (TDLAS) and Differential Optical Absorption Spectroscopy (DOAS) gas absorption technology with independent intellectual property rights. The specially designed measuring cell effectively improves optical path length for gas absorption, which can measure trace gas accurately inside pipeline PLGT-450 can be widely applied in online gas monitoring occasions including denitrification device, boiler flue and exhaust detection, etc. One equipment can realize online monitoring for multiple gas components, such as CO, CO2. SO2, NO, NO2, etc.

System Flow Path : 

Under effect of high-temperature sampling pump, high-temperature process gas passes through prefilter, sampling probe and secondary filter before entering gas analysis module for gas concentration monitoring and at last it will be discharged. For better application, it is equipped with high-temperature electrical heat tracing inside equipment and the parts directly contacting with chimney pipe adopt anti-corrosion treatment, which can effectively solve the problems of process gas absorption (caused by gas condensation), dissolution (caused by gas condensation) or corrosion. To avoid dust blocking, the device will close sampling valve automatically and control purge valve to clean filter element at fixed time, ensuring long-term and stable operation of system.
