61-7065-14 Fireye Inner Assembly

Overview

The Fireye 61-7065-14 is a 14-foot (4268 mm) inner carrier assembly designed for use with Fireye Phoenix flame scanners. It serves as a critical component in fiber optic flame detection systems, particularly in environments where the target flame is obscured by burner hardware such as movable vanes, air compartments, or nozzles. This assembly utilizes high-temperature glass optics to transmit flame radiation from the combustion zone to the scanner electronics located outside the burner windbox.

Features

• Flexible Fiber Optic Design: Enables flame monitoring in applications where a direct line of sight is unavailable due to mechanical obstructions.
• High-Temperature Glass Optics: Specifically engineered to withstand the extreme heat of industrial burner environments while providing clear signal transmission.
• Robust Construction: Features a 303 stainless steel mounting head and a durable carrier assembly to ensure long-term reliability in harsh conditions.
• Integrated Components: The assembly typically includes the fiber optic bundle, objective lens, and necessary mounting ferrules for a complete installation within an outer carrier.

Applications

The Fireye 61-7065-14 is used in industrial and commercial boiler applications where standard surface-mounted scanners cannot effectively view the flame. It is ideal for monitoring individual burner flames in complex furnace configurations, such as those with tilting burners or multi-fuel environments. By positioning the objective lens near the windbox-furnace interface, it allows for precise discrimination of a specific burner’s flame even within a larger fireball.
