61-7080-6 Fireye Inner Assembly

Overview

The Fireye 61-7080-6 is a 6-foot quartz inner carrier assembly specifically designed for use with the Fireye InSight I (Series 95S) integrated flame scanners. This component serves as a critical optical conduit in fiber optic scanner arrangements, allowing for flame detection in environments where a standard surface-mounted scanner cannot maintain a clear line of sight to the target flame. It is typically utilized in large utility or industrial boilers where burner components might otherwise obstruct the scanner’s view.

Features

• Flexible fiber optic design enables flame monitoring in complex burner geometries and moving burner nozzles.
• High-temperature quartz optics ensure reliable transmission of ultraviolet and infrared radiation from the flame.
• Durable stainless steel construction protects the fiber optic bundle from the harsh conditions inside a burner windbox.
• Precision-engineered for seamless integration with InSight I scanner electronics.
• Helps maintain stable optical alignment for accurate flame signal processing and discrimination.

Specifications

• Part Number: 61-7080-6
• Length: 6 feet (1828 mm)
• Material: High-temperature quartz fiber optics
• Housing: Flexible and rigid stainless steel tubing
• Compatibility: Designed for Fireye InSight I Series 95S flame scanners
• Purge Air Connection: Typically requires 3/8 inch NPT cooling/purge air inlet to keep optics clean and cool
• Temperature Rating: Quartz optics rated for high-temperature combustion environments

Applications

The 61-7080-6 is primarily used in industrial and utility boiler applications where individual burner flames must be monitored independently. It is ideal for burners with movable vanes, air compartments, or tilting nozzles that would obscure a conventional scanner. By bringing the flame radiation from the objective lens near the burner tip back to the scanner electronics located outside the windbox, it ensures reliable flame safeguard and burner management system operation in power plants, refineries, and large-scale manufacturing facilities.
