61-6960-6 Fireye Inner Assembly

Overview

The Fireye 61-6960-6 is a 6-foot (1828 mm) replacement inner carrier assembly designed for use with Fireye InSight I fiber optic flame scanners. This assembly utilizes high-temperature glass optics to transmit flame radiation from the burner area to the scanner electronics located outside the windbox. It is specifically engineered for industrial burner applications where moving components, such as vanes or air compartments, would otherwise obstruct the line of sight for conventional surface-mounted scanners.

Features

• High-temperature glass optics for reliable flame signal transmission.
• 6-foot overall length to reach deep into combustion zones.
• Flexible stainless steel forward carrier section for easier installation in complex burner geometries.
• Rigid black iron pipe rear carrier section for structural stability.
• 303 stainless steel mounting head to withstand harsh industrial environments.
• Integrated fiber optic bundle that brings radiation to the external detector.

Applications

The 61-6960-6 is primarily used in large boiler and industrial furnace applications. It is ideal for monitoring flames past movable burner vanes, detecting combustion in obstructed air compartments, and maintaining a steady flame signal near tilting burner nozzles. It is frequently employed in systems where individual burner flames must be distinguished within a larger fireball, provided the fuel ignites before entering the main furnace fireball.
