Specifically designed for the harsh environment within glass and ceramics furnaces, the Alumina protection tube protects the in-situ oxygen sensor from the silica wash. Installed either in the regenerator crown, or in the regenerator target wall (opposite the port), the Oxyfire sensor measures excess oxygen remaining from the combustion process. This gives the glass furnace operators a method to automatically and/or manually trim the air dampers to minimize excess oxygen.

UPC-Marathon optimizes the combustion system by “trimming” the air/fuel ratio. By maintaining a constant excess oxygen measurement in the glass tank, the UPC-Marathon combustion optimization system contributes to glass quality and bottom-line savings.
