61-6305 Fireye Outer Assembly

Overview

The Fireye 61-6305 is a 10-foot (3048 mm) outer carrier assembly designed for use with Fireye fiber optic flame scanner systems, specifically compatible with InSight II and Phoenix scanners. This assembly is a critical component in burner applications where obstructions like movable vanes or air compartments prevent a standard surface-mounted scanner from maintaining a clear line of sight to the flame. The outer carrier is permanently fastened to the boiler, providing a protective housing for the inner carrier assembly that contains the sensitive quartz or glass fiber optic bundles.

Features

• Protective Housing: Serves as a durable, permanent conduit for inner carrier assemblies and fiber optic bundles.
• Flexible and Rigid Construction: Engineered with a combination of flexible and rigid stainless steel to navigate complex burner windbox environments.
• Optimized Length: At 10 feet long, it is designed for deep-entry applications in large industrial boilers.
• High-Temperature Resistance: Constructed from materials capable of withstanding the intense heat of combustion environments.
• Precise Alignment: Ensures the fiber optic objective lens remains aimed at the target flame even as burner components move.

Specifications

• Model Number: 61-6305
• Nominal Length: 10 feet (3048 mm)
• Compatibility: Used with Fireye InSight II and Phoenix scanner series
• Materials: High-grade stainless steel for both flexible and rigid sections
• Mounting: Typically features a hexagonal mounting head (1-1/2 inch across flats) for secure welding or attachment to the burner/boiler mechanism
• Component Requirement: Part of a three-piece system (Scanner, Inner Carrier, and Outer Carrier)

Applications

The 61-6305 outer carrier assembly is used in industrial and commercial boiler applications where individual burner flames must be monitored within a complex furnace fireball. It is specifically intended for burners with movable air vanes or nozzles that would otherwise obscure the flame from a conventional scanner. By bringing the flame radiation through the windbox to an external detector, it allows for reliable flame safeguard and monitoring in challenging line-of-sight conditions.
