TDLAS Laser Gas Analyzer for Metallurgical Gas Emissions Online Monitoring
The KF200 series laser gas analyzer is developed aiming at industrial on-line analyzing and online environmental monitoring. Based on the semiconductor laser absorption spectroscopy (DLAS) technology, it is developed with features of an integrated design and high level of integration.
There are various types of the KF200 series laser gas analyzer, including in-situ probing type, by-pass type, multi-channel and disc mounted type, etc. Gases like O2, CO, NH3, CO2, CH4, H2O, HC, HF, etc., can all be analyzed. The concentration analyzing of target gases includes the macro-analysis and micro-analysis.
Technical Features:
- The TDLAS technology is adopted for in-situ online gas analyzing;
- Double-proof probe design negates positive pressure purge, with no additional data processing unit, a simple compact structure and high reliability;
- Using high-power lasers, no fiber coupling, suitable for harsh working conditions (such as with excessive dust);
- Using the patented technology of spot light path adjustment, easy for on-site installation.
- Explosion-proof design, friendly on-site installation;
- Auto - calibration and auto-back flushing.

Main Process
Under the influence of the jet pump, the target gases are processed through probe filter (filtering out dust), heat tracing (avoid raw condensate production), cooling (for high-temperature applications), and inlet laser analysis module for analyzing and measuring. Close the ball valve, open the calibration valve and then do calibration of the laser analysis module. It ensures the accuracy of the device running. Close the ball valve and open the backflushing valve to ensure the sampling passage unblocked.
The configuration of KF200 laser gas analyzer varies based on different applications. For high-pressure situations, pressure reducing valves should be increased, the jet pump not needed.
