Fireye Introduces the 85UVF1A-1QDK3: A Next-Generation Digital Flame Scanner for Enhanced Burner Management Safety

HAMPTON, NH – Fireye, a global leader in combustion and burner management controls, proudly announces the release of its new digital flame scanner, the 85UVF1A-1QDK3. Designed for heavy-duty industrial and utility applications, this advanced scanner sets a new benchmark for reliability, diagnostics, and integration in critical flame monitoring for large gas, oil, or dual-fuel burners found in boilers, heaters, and process furnaces.

The 85UVF1A-1QDK3 represents the latest evolution in Fireye’s proven line of UV/IR flame detectors. Combining a rugged, high-sensitivity UV sensor with intelligent digital signal processing, this scanner excels in challenging environments where flame stability, safety, and process continuity are paramount. Its sophisticated electronics reliably distinguish between the true UV signature of a fuel flame and background furnace radiation or hot refractory glow, drastically reducing the risk of nuisance trips and improving overall boiler availability.

At the core of its innovation is the unit’s digital communication capability. Featuring integrated HART® (Highway Addressable Remote Transducer) protocol, the 85UVF1A-1QDK3 enables rich, bidirectional communication with modern distributed control systems (DCS) or asset management software. Operators can now remotely monitor scanner status, view real-time signal strength, access diagnostic data, and perform configuration changes without the need for physical access to the burner front—a significant enhancement for operational efficiency and personnel safety in high-temperature zones.

“The 85UVF1A-1QDK3 is more than a flame detector; it’s a smart combustion asset,” said a Fireye Product Line Manager. “By providing unprecedented visibility into flame conditions and scanner health, we empower plant engineers to move from reactive maintenance to predictive operations. This directly supports our mission to deliver uncompromising safety while maximizing asset uptime and simplifying compliance.”

Key Features and Benefits:

Superior Flame Discrimination: Advanced digital algorithms ensure high immunity to false signals from hot backgrounds and spurious radiation, providing confident flame-on/flame-off status.
Integrated HART Communications: Enables remote monitoring, configuration, and diagnostics, facilitating integration into plant-wide predictive maintenance strategies.
Robust Industrial Design: Built to withstand high temperatures, vibration, and harsh environments typical of large-scale combustion systems.
Enhanced Diagnostics: Continuous self-monitoring for faults such as lens blockage, sensor aging, or circuit failure, providing early warnings to prevent unscheduled shutdowns.
Simplified Compliance: Aids in meeting stringent safety standards (e.g., NFPA 85, FM, UL) for burner management systems with its reliable performance and diagnostic capabilities.

Applications and Availability

The Fireye 85UVF1A-1QDK3 digital flame scanner is ideally suited for utility boilers, industrial watertube and firetube boilers, process heaters, and other large combustion systems. It is available now through Fireye’s global network of authorized distributors and combustion engineering specialists. Comprehensive technical support, documentation, and configuration tools are provided to ensure optimal implementation and performance.
