61-6960-10 Fireye Inner Assembly

Overview

The Fireye 61-6960-10 is a 10-foot (3048 mm) inner carrier assembly designed for use with Fireye InSight flame scanners. It serves as a critical component in fiber optic scanner systems, particularly where movable burner vanes, air compartments, or complex burner nozzles obstruct the direct line of sight for conventional scanners. This assembly utilizes high-temperature glass optics to transmit flame radiation from the combustion zone to the scanner electronics located outside the windbox.

Features

• Flexible Fiber Optic Design: Enables flame monitoring in applications with obstructed views or tilting burner nozzles.
• Glass Optics: Utilizes high-temperature glass bundles for reliable signal transmission.
• Durable Construction: Features a 303 stainless steel hexagonal mounting head and a combination of flexible and rigid stainless steel carrier materials to withstand harsh industrial environments.
• Integrated Components: Comes as a complete assembly that typically includes a flange, air port, fiber bundle, and lens assembly.
• Extended Reach: The 10-foot length allows the sensor to access deep combustion zones for accurate signal detection.

Applications

The 61-6960-10 inner carrier assembly is primarily used in large industrial and utility boilers. It is specifically designed for burners with complex internal geometries, such as those with movable vanes or nozzles that prevent a standard surface-mounted scanner from maintaining a clear line of sight to the target flame. It is ideal for monitoring individual burner flames within a multi-burner furnace environment, ensuring accurate flame discrimination and safety monitoring.
