61-6960-12 Fireye Inner Assembly

Overview

The Fireye 61-6960-12 is a 12-foot (3658 mm) inner carrier assembly featuring glass fiber optics, specifically designed for use with Fireye InSight I (95 Series) integrated flame scanners. This component is an essential part of a fiber optic scanner system, designed for applications where a direct line of sight to the flame is obstructed by burner components such as movable vanes, air compartments, or complex burner geometries. It serves as the internal conduit that transmits flame radiation from the combustion zone to the scanner’s electronics located safely outside the windbox.

Features

• Extended Reach: The 12-foot length allows for deep penetration into large industrial boilers to reach optimal sighting locations.
• Glass Fiber Optics: Utilizes high-temperature glass fibers designed to transmit clear flame signals for reliable detection.
• Durable Construction: Features a 303 stainless steel mounting head to withstand the harsh thermal and mechanical conditions of a burner front.
• Integrated Design: The assembly is engineered for seamless integration with the InSight I scanner, ensuring precise alignment and signal integrity.
• Flexible Protection: The forward carrier section is typically constructed of flexible stainless steel to navigate burner internals, while the rear remains rigid for stable mounting.

Applications

The 61-6960-12 is primarily used in industrial and commercial combustion systems, particularly in large utility boilers and process heaters. It is ideal for installations where the burner flame may move (due to tilting tangential burners) or where mechanical obstructions like cooling air ports and burner vanes prevent a standard scanner from maintaining a clear view. It is commonly employed in systems firing gaseous fuels or light oils where glass optics provide the necessary spectral response for flame monitoring.
