AMETEK Thermox combustion analyzer adds safety support and improves efficiency and pollution monitoring

Applications include:
• Coal & gas fired power generation
• Petrochemical & chemical refining
• Pulp & Paper
• Institutional & government facility power plants

The WDG-V analyzer monitors hot, wet flue gas for excess oxygen. It also allows operators to lower emissions of NOx, CO and CO2 and improve operating efficiency in power generation and petrochemical refining. Reliable detection of excess oxygen and combustibles in a fired heater or boiler are critical to the effectiveness of burner management systems. The WDG-V also monitors for methane for safe burner startup.

Unique features of the new combustion analyzer include:
• An improved aspirator design with larger orifice sizes and improved response times even with flame arresters installed
• Low-flow sample alarm that monitors combustion gas flow at the sensors and provides an indication of low sample flow
• Automatic verification of cell and detector response to ensure proper accuracy and operation
• Cell and detector age tracking for proactive calibration or service scheduling

The WDG-V mounts directly to the process flange and is heated to maintain all sample wetted components above the acid dewpoint. Its air-operated aspirator draws a sample into the analyzer and returns it to the process.
