Ametek WDG-V Combustion Analyzer

Why the need for an Ametek WDG-V Combustion Analyzer? The reliable identification of low combustion oxygen in a fired heater or boiler has always been critical to the effectiveness of the Burner Management System for proper control and safety.

Ametek WDG-V Combustion Analyzer for increased efficiency and emission reductions

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.

The Ametek WDG-V Combustion Analyzer has been designed to provide an additional layer of safety with the measurement of excess O2, Combustibles and Methane and by using these measurements to ensure the safe operation of the Burner Management System.
