Product Description

Pulverized coal bunker CO/O2 analyzer is an electrical instrumentation equipment designed for blast furnace coal injection system online continuous detection of gas composition. Gas in the mill is sampled by instrument sampling probe installed on the mill (or mill outlet piping).Under the action of jet pump, sampling gas through probe filtering, heating and cooling (for high temperature occasion), then enter bypass tube (laser analysis module) for analysis measurement.


1. Using the TDLAS technology to avoid the influence of gaseous water and interferentialgas on CO measurement
2. High stability, long calibration cycle, low maintenance quantity
3. Supportting automatic calibration, automatic blowback
4. No mechanical moving parts, vibration resistance interference


1. Installation mode: bypass
2. Response time: ≤5s (T90)
