UPC Oxyfire High-Temperature Oxygen Sensor

This in-situ oxygen sensor measures oxygen concentrations directly in the "high heat" zones of high temperature furnaces, boilers and incinerators. They are intrinsically safe, requiring no electrical input power, and generating only a low millivolt output.



The OxyFire sensors allow for continuous, accurate oxygen measurement and control in the combustion zone. Reduction in excess O2 will reduce emissions of combustion by-products such as SO2, NO2 and CO. The products perform with little maintenance. Sensor endurance in the aggressive environment of a container glass furnace is typically 18 months. Replacement is a simple process which can be performed by on-site personnel. UPC Applications Engineers can assist customers in selecting the proper oxygen sensor technology and sensor placement within the furnace for optimal usage.

Users have been able to reduce fuel by up to 1-2% for every 1% reduction in Excess Oxygen
