AMETEKThe Thermox® WDG-V combustion analyzer measures oxygen, combustibles and methane levels in hot, wet flue gas. The WDG-V analyzer provides a reliable and cost-effective solution for monitoring combustion, reducing excess oxygen, and lowering emissions of NOx, CO and CO2. The reliable detection of low-combustion oxygen and/or high or low combustibles (CO) in a fired heater is critical to the effectiveness of burner management systems. The addition of a WDG-V combustion analyzer provides a layer of control and safety to a basic process control system while significantly reducing the risk of an uncontrolled combustion event. This instrument can enable control and safety permissive, interlock and shutdown functions for burner management systems.
