Flue Gas Analyser

The GCEM4000 is an accurate, reliable in-situ flue gas analyser that measures gases by infrared absorption gas filter correlation (GFX) technology. It is capable of continuously measuring seven gases at a time. The GCEM4000 measuring probe is mounted on the stack/duct and uses an intrusive stainless steel measurement chamber equipped with sintered diffuser filters to allow flue gas excluding particulate into the measurement chamber. Infra red beam from transceiver unit passes through the probe measurement chamber and is reflected back to the infrared detector mounted within the transceiver unit through a gold-coated mirror. Analyser utilising an in-situ probe arrangement allows analyser calibration to be verified quickly and easily by the injection of zero and span gases via gas calibration controller (GCC). The SmartCEM station control unit (SCU) provides power to and communicates with the analysers and monitors within that station. GCC and SCU are mounted inside the CEM enclosure. The GCEM4000 continuously measures H2O, CO2, pressure and temperature measurement to carry out online normalisation to the standards required by pollution control board. Features: in-situ probe-no sampling/heating/conditioning of gases; can measure up to seven gases using IR gas filter correlation technology; highly accurate zero maintenance; full zero and span verification using audit gases; real time normalisation for STP, moisture and CO2; optional – 5 years remote data logging, reporting and remote diagnostics via PC software package; remote access for diagnostic checks via modem; MCERTS approved; compliance to US EPA standards; and EMC and LVD compliant.
