61-6960-3 Fireye Inner Assembly

Overview

The Fireye 61-6960-3 is a 3-foot (914 mm) inner carrier assembly specifically designed for use with Fireye InSight I fiber optic flame scanners. This assembly is a critical component for monitoring burner flames in environments where a standard surface-mounted scanner’s line-of-sight would be obstructed by movable vanes, air compartments, or burner nozzles. It features glass optics to transmit flame radiation from the combustion zone to the scanner electronics located outside the windbox.

Features

• Specialized 3-foot length for precise positioning within industrial burner setups.
• High-temperature glass optics for reliable flame signal transmission.
• Designed to integrate seamlessly with InSight I series fiber optic scanner assemblies.
• Flexible and rigid carrier components to facilitate installation through boiler windboxes.
• Includes necessary objective lens and fiber bundle to deliver radiation to the detector.

Applications

The 61-6960-3 inner carrier assembly is used in industrial and commercial boiler applications where standard flame scanners cannot be mounted with a direct view of the flame. It is typically employed in systems featuring tilting burner nozzles or complex air compartment geometries. By utilizing this fiber optic assembly, operators can ensure accurate individual burner flame detection even within the “fireball” of a large furnace.
