61-6872-14 Fireye Fiber Optic

Overview

The Fireye 61-6872-14 is a 14-foot quartz fiber optic bundle designed for industrial burner applications where a direct line of sight between the flame and a surface-mounted scanner is obstructed. By transferring flame radiation from the burner area to scanner electronics located outside the windbox, it ensures reliable flame detection in complex combustion environments. This assembly is engineered to withstand high temperatures and requires careful handling to maintain the integrity of the quartz fibers.

Features

• High-quality quartz optics provide reliable transmission of ultraviolet (UV) flame signals.
• 14-foot length allows for flexible routing around burner components and through windboxes.
• High-temperature end tip is designed to withstand harsh combustion zone environments up to 400C.
• Protective metal sheathing or carrier housing safeguards the delicate fiber bundle from mechanical damage.
• End markings assist technicians in achieving proper alignment between the flame and the scanner electronics.

Applications

The Fireye 61-6872-14 is primarily used in power generation and large industrial boiler systems. It is ideally suited for monitoring tilting burner flames or installations where diffusers and burner apparatus obscure the target flame. It is also commonly employed in process heating and enclosed burner zones where the scanner electronics must be mounted externally to avoid extreme heat or physical interference.
