61-4842-11 Fireye Fiber Optic

Overview

The Fireye 61-4842-11 is a replacement glass fiber optic bundle designed for use in specialized flame monitoring systems. It acts as a conduit for light radiation, transmitting the flame signal from the burner’s interior to a flame scanner located outside the windbox. This is particularly useful in burner configurations where the line of sight is obstructed by internal components like movable vanes or air compartments.

Features

• Flexible glass fiber construction allows for installation in complex burner geometries where a straight sight path is unavailable.
• Designed to withstand high-temperature industrial environments.
• Includes a protective stainless steel outer shielding to prevent mechanical damage during installation and operation.
• Compatible with a wide range of Fireye flame scanners, including the InSight and Phoenix series.

Specifications

• Model Number: 61-4842-11
• Length: 17.5 feet (5334 mm)
• Material: Glass fiber optic
• Operating Temperature: Glass bundles are typically rated for a maximum temperature of 800 degrees Fahrenheit (427 degrees Celsius) at the “hot” end.
• Compatibility: Used with Fireye 95IR, 85IR, 45FS, and 45RM scanners.

Applications

The 61-4842-11 fiber optic bundle is primarily used in industrial boiler and burner applications. It is essential for monitoring individual burner flames in large furnaces where multiple flames may merge into a single “fireball,” making it difficult for standard surface-mounted scanners to distinguish between them. It is commonly employed in power plants, refineries, and large-scale manufacturing facilities.
