61-7080-12 Fireye Inner Assembly

Overview

The Fireye 61-7080-12 is a 12-foot (3658 mm) inner carrier assembly featuring quartz fiber optics, specifically designed for use with Fireye InSight I series integrated flame scanners. This specialized assembly is engineered for burner environments where the target flame may be obscured or moved by adjustable vanes, air compartments, or burner nozzles, making a direct line-of-sight for surface-mounted scanners impossible. The quartz bundle efficiently transmits ultraviolet and infrared radiation from the combustion zone to the scanner electronics located outside the burner windbox.

Features

• Quartz fiber optic construction provides superior transmission of flame radiation for precise detection.
• 12-foot extended reach allows for monitoring in deep or complex combustion zones.
• Flexible stainless steel housing protects the fiber optic bundle from mechanical damage and industrial wear.
• Integrated design includes a specialized mounting head to maintain optical alignment.
• “Hot” and “cold” end indicators (marked with “H”, “C”, and blue markers) ensure correct installation of the fiber bundle within the carrier.

Specifications

• Model Number: 61-7080-12
• Length: 12 feet (3658 mm)
• Optical Material: Quartz Fiber
• Compatibility: Fireye InSight I (Series 95DSS2) Flame Scanners
• Temperature Rating: Designed for high-ambient industrial burner environments
• Construction: Flexible stainless steel outer tubing with rigid rear carrier sections

Applications

The 61-7080-12 is primarily used in large industrial and utility boilers, particularly those firing gaseous or liquid fuels where individual burner discrimination is required within a common fireball. It is essential in applications involving tilting tangential burners or low-NOx burner configurations where the flame front may shift during operation. The assembly is commonly found in power generation, chemical processing, and large-scale manufacturing facilities utilizing Fireye burner management systems.
