FIREYE | 85UVF1A-1QD FLAME SCANNER

The Fireye 85UVF1A-1QD is a sophisticated, microprocessor-based ultraviolet (UV) flame scanner. It is a critical safety component used in industrial burner management systems to detect the presence or absence of a flame. By monitoring UV radiation, it ensures that fuel is not supplied to a burner if a flame is not established, preventing dangerous accumulations of unburned fuel.

Product Specifications

Application Fields

This scanner is designed for mission-critical flame monitoring in harsh environments:

• Utility Boilers: Large-scale power generation burners.
• Industrial Furnaces: Flame monitoring in process heaters and chemical furnaces.
• Oil & Gas Refineries: Managing burners for process heaters and thermal oxidizers.
• Waste-to-Energy Plants: Monitoring complex combustion profiles for diverse fuel types.

Product Usage Instructions

1. Mounting: Mount the scanner using a dedicated sight tube, ensuring it has a clear line-of-sight to the primary combustion zone. Use the provided cooling/purge air connection to prevent lens fouling and overheating.
2. Setup: Use the Fireye InSight software via the RS-485 interface to configure the scanner’s sensitivity, flicker frequency, and flame-on/off thresholds.
3. Cabling: Use the recommended Fireye 1QD-series quick-disconnect cable. Ensure that the cable shield is grounded at the controller end only to prevent ground loops.
4. Maintenance: Regularly inspect the quartz lens for soot or dust buildup. Use a soft, non-abrasive cloth and isopropyl alcohol if cleaning is required.

Q&A: Frequently Asked Questions

Q: What does the “UVF” designation indicate?

A: It indicates that the scanner is optimized for detecting UV light emitted by the flame, which is ideal for fuels that produce low-visible-light flames (like many gas-fired burners).

Q: Can this scanner communicate with my PLC/DCS?

A: Yes, it features an integrated RS-485 Modbus interface, allowing you to stream flame intensity, gain, and status data directly to your plant control system for monitoring and trend analysis.

Q: Why use a “1QD” (Quick-Disconnect) model?

A: The “QD” model allows for rapid replacement of the scanner without needing to rewire the entire terminal box, significantly reducing downtime during scheduled maintenance or emergency repairs.
