61-7080-9 Fireye Inner Assembly

Overview

The Fireye 61-7080-9 is a 9-foot inner carrier assembly featuring quartz fiber optics, specifically designed for use with Fireye InSight series integrated flame scanners. This assembly is a critical component of a fiber optic scanner system, housing the delicate fiber optic bundle and lenses necessary to transmit flame radiation from the burner to the scanner electronics. It is engineered for industrial burner environments where a direct line of sight is obstructed or where high temperatures require the electronic components to be remotely located from the furnace windbox.

Features

• Quartz Fiber Optic Bundle: Utilizes high-quality quartz fibers suitable for detecting both ultraviolet (UV) and infrared (IR) radiation.
• Specialized Lenses: Includes an objective lens assembly at the front end to accurately capture flame flicker and intensity.
• Durable Construction: Built with a combination of flexible and rigid stainless steel tubing to protect the fiber optics while allowing for installation in complex burner geometries.
• Temperature Resilience: Designed to withstand high ambient temperatures, with quartz optics rated for up to 752 degrees F (400 degrees C) at the hot end.
• Color-Coded Orientation: Features etched markers (H/C) and colored indicators to ensure correct orientation of the “hot” and “cold” ends during installation.

Specifications

• Model Number: 61-7080-9
• Nominal Length: 9 feet (2743 mm)
• Material: 303 Stainless steel mounting head and stainless steel carrier housing
• Optics Type: High-temperature quartz
• Compatibility: Designed for use with Fireye InSight I (95 Series) and InSight II (95DSS3) scanners
• Component Type: Inner Carrier Assembly

Applications

The 61-7080-9 is primarily used in large-scale industrial and utility boiler applications, such as power generation. It is ideal for monitoring burners with movable vanes, air compartments, or complex nozzles that would otherwise obscure the target flame from a standard surface-mounted scanner. By positioning the objective lens near the interface of the windbox and furnace, this assembly allows the InSight scanner to effectively discriminate between the target burner flame and background radiation in a multi-burner environment.
