61-4842-6 Fireye Fiber Optic

Overview

The Fireye 61-4842-6 is a professional-grade replacement glass fiber optic bundle designed for industrial flame monitoring and safeguard systems. It is specifically engineered for applications where a standard surface-mounted scanner cannot maintain a clear line of sight to the target flame due to physical obstructions like burner nozzles, air compartments, or movable vanes. This bundle transmits flame radiation from a lens assembly located inside the windbox to a scanner electronics assembly mounted externally, ensuring reliable flame detection in complex burner configurations.

Features

• Glass fiber optic construction optimized for infrared (IR) flame radiation transmission.
• Flexible stainless steel protective housing to prevent mechanical damage during installation and operation.
• Extended length allows for remote mounting of scanner electronics away from high-heat zones.
• Designed for use with specific Fireye integrated and non-integrated scanners such as the 95IR, 85IR, 45FS, and 45RM series.
• Facilitates individual burner flame discrimination in multi-burner boiler applications where flames might otherwise merge into a single fireball.

Applications

The 61-4842-6 fiber optic bundle is primarily used in industrial and commercial boiler systems, power generation plants, and large-scale combustion processes. It is ideal for burners with complex geometry where the flame is obscured from traditional mounting positions. Common applications include utility boilers where individual burner monitoring is required for safety and efficiency, and environments where the scanner electronics must be protected from extreme ambient temperatures by being located further from the burner front.
