60-2721-6 Fireye Scanner

Overview

The Fireye 60-2721-6 is a high-performance replacement electronics assembly designed for the InSight II series integrated flame scanners, specifically the 95DSS2E-1CEX model. This microprocessor-based component is a critical part of industrial flame safeguard systems, combining both infrared (IR) and ultraviolet (UV) sensors to provide reliable flame detection and discrimination. By integrating the sensing and amplification functions into a single unit, it eliminates the need for remote flame amplifiers while providing sophisticated diagnostic and setup capabilities through its onboard interface.

Features

• Dual Sensor Technology: Utilizes both solid-state infrared and ultraviolet sensors to monitor a wide range of fuel types and flame characteristics.
• Integrated Flame Relay: Features an internal flame relay with adjustable ON/OFF thresholds for direct control without external amplification.
• Self-Checking Circuitry: Includes electronic self-checking to ensure continuous fail-safe operation without the need for a mechanical shutter.
• User Interface: Equipped with an alpha-numeric display and keypad for viewing operating parameters, signal strength, and selecting setpoints.
• Advanced Discrimination: Offers 21 selectable modulation frequencies to optimize flame-on/flame-off discrimination and reduce nuisance trips.
• Multiple Memory Files: Supports four independent programmable files to accommodate different fuels or firing rates.

Applications

The 60-2721-6 is used across various industrial combustion sectors including power generation, chemical processing, and manufacturing. It is specifically applied in:

• Multi-burner furnaces and boilers where discriminating between adjacent flames is critical.
• Complex firing environments such as coal-fired power stations, hazardous waste incinerators, and municipal solid waste plants.
• Industrial process heaters and kilns (e.g., cement kilns and steel mills) requiring robust flame monitoring.
• Recovery boilers in black liquor plants and combine cycle power plants.
