61-7065-10 Fireye Inner Assembly

Overview

The Fireye 61-7065-10 is a 10-foot (3048 mm) inner carrier assembly designed specifically for use with Fireye Phoenix series integrated flame scanners. This component is part of a fiber optic scanner system used in industrial burner applications where a direct line of sight to the flame is obstructed or moving parts like air compartments or burner nozzles are present. It serves as the internal housing for the fiber optic bundle, ensuring precise delivery of flame radiation from the burner windbox to the scanner electronics located outside.

Features

• Glass fiber optic bundle optimized for specific infrared or visible light flame detection.
• 10-foot nominal length for deep burner installations or large boiler windboxes.
• High-temperature construction to withstand the extreme environment near the furnace interface.
• Integrated objective lens assembly to focus flame radiation into the fiber bundle.
• Flexible stainless steel protective tubing for the internal bundle.
• Quick-connect design for easy insertion and removal from the outer carrier assembly.

Applications

The 61-7065-10 is used in industrial and utility boilers, particularly those with complex burner geometries such as tangentially-fired boilers or burners with tilting nozzles. It is ideally suited for monitoring individual burner flames in a multi-burner environment where conventional scanners cannot be mounted. Common applications include coal-fired power stations, refineries, hazardous waste incinerators, and low NOx burner systems where accurate flame signal transmission is critical for burner management safety.
