Continuous Emissions Monitoring (CEM)

  • Model CEM Oxygen Analyzer
    CEM Oxygen Analyzer

    Continuous Emissions Monitoring systems using hot-wet extractive systems take the flue gas sample from the exit of wet-scrubbers. A hot-wet oxygen measurement is taken from the incoming feed line to the CEM system analysis cabinet. The oxygen analyzer used for this measurement must be equipped to keep the sample gas above the dew point and compact to fit within the restricted space of the analysis cabinet.

    WDG-V Combustion Analyzer

    Low emission burners and aggressive firing control points to achieve increased efficiency and emission reductions have driven the industry to tighter control measures. But tighter control measures also hold a greater potential for combustion events. Reducing the risk of a combustion event has become a priority and has led to the implementation of Safety Instrumented Systems (SIS). This additional layer of safety is added to the Basic Process Control System.

    WDG 1200 & 1210 Insitu

    The WDG 1200 Insitu and the WDG 1210 Insitu are rugged, reliable flue gas analyzers for net oxygen that use industry-proven zirconium oxide sensor technology. The outer probe tube is 310 stainless steel so no abrasion shield is needed for most applications. The controller features precision temperature control for optimum stability, built-in diagnostics, and over-temperature protection. Modbus and 4-20 mA outputs are standard; automatic calibration is available. The unique sensor design allows the entire sensor assembly, including the heater, to be removed without disturbing the outer protection tube which remains in the process. This makes field service fast and easy, and because there is no need to return the probe to the factory for repair, there’s no expensive downtime.

    WDG Insitu Probe

    Modern gas, oil and coal fired boiler operations require dependable, low-maintanence, application flexible devices to monitor and control combustion processes. The measurement of excess oxygen in flue gas is particularly important for obtaining maximum combustion fuel efficiency while minimizing thermal or fuel-bound Nitrogen oxides generation. The zirconium oxide insitu probe has become the industry standard for making this flue gas-oxygen measurement. However, most insitu probe designs do not afford ideal accessibility to filter, cell and heater components, requiring removal of the probe from the process flange for servicing.
