61-7064-3 Fireye Inner Assembly

Overview

The Fireye 61-7064-3 is a 3-foot (914 mm) inner carrier assembly featuring quartz fiber optics, specifically designed for use with Fireye Phoenix series integrated flame scanners. This component is essential for installations where a direct line of sight to the flame is obstructed by movable vanes, air compartments, or burner nozzles. By utilizing flexible stainless steel tubing to house the quartz fiber bundle, it transmits flame radiation from the furnace interface to the scanner electronics located safely outside the windbox.

Features

• High-quality quartz fiber optic construction for superior ultraviolet (UV) signal transmission.
• Flexible stainless steel housing to protect the delicate fiber optics in demanding industrial environments.
• 3-foot (914 mm) length suitable for specific burner geometries requiring offset mounting.
• Hot and cold end indicators for precise installation, with the cold end featuring a blue marker and “C” etching.
• Compatible with Fireye Phoenix Series 2 (85 Series) scanners for integrated flame monitoring.

Specifications

• Part Number: 61-7064-3
• Length: 3 feet (914 mm)
• Optics Material: Quartz
• Compatible Scanners: Phoenix Series 85UVF / 85IRF
• Operating Temperature: Designed to withstand high-temperature windbox environments at the objective lens end.

Applications

The 61-7064-3 is primarily used in industrial and commercial boiler applications where conventional surface-mounted scanners cannot effectively view the burner flame. It is ideal for monitoring individual burner flames in complex configurations, such as duct burners, refinery process heaters, and multi-burner furnaces where individual flame discrimination is required despite the presence of a fireball or mechanical obstructions.
