ABB FAU810 Uvisor™ Flame Analysis Unit

Key Features & Functions

• Universal Detector Compatibility: Processes signals from any type of ABB flame detector, including the legacy DFS series and the advanced Uvisor™ SF810, ensuring a unified platform across different scanner technologies .

• Intelligent Signal Processing: Collects raw signal values from the flame detector to calculate flame quality, strength, frequency, and flicker. It continuously evaluates these parameters to assess combustion stability .

• Comprehensive Fault Detection: Continuously monitors the system and detector health, immediately signaling unsafe conditions such as lens soiling, detector failure, or flame loss to ensure burner safety .

• Redundant & Flexible Communication: Equipped with redundant Profibus DP-V1 and standard Modbus interfaces for seamless and safe data exchange with plant control systems (DCS/PLC), enabling remote tuning and monitoring .

• Real-Time Diagnostics: When paired with ABB’s Flame Explorer™ software, it enables crucial real-time diagnostics and safe remote monitoring of combustion performance .

• Advanced Combustion Insight: Supports PYRO technology-enabled scanners to provide real-time flame temperature measurement, allowing for precise air-fuel ratio optimization, reduced emissions, and improved efficiency .

Application Scenarios

• Utility Power Plants (Coal, Gas, Oil): Monitoring individual burner flames in large boilers to prevent unburned fuel accumulation and ensure safe boiler light-off and operation .

• Industrial Boilers: Providing flame quality feedback for process heaters and steam generators in refineries, chemical plants, and manufacturing facilities .

• Multi-Fuel Combustion Monitoring: Supporting plants that burn a mix of fuels (biomass, lignite, heavy oils, refinery gas) by offering wide tunability to adapt to different flame characteristics .

• Burner Management Systems (BMS): Acting as the primary flame-sensing logic solver to validate pilot and main flame presence before fuel is admitted, in compliance with safety standards .

• Retrofit Projects: Upgrading aging flame detection systems in existing power plants with modern digital communication and diagnostic capabilities without replacing the entire boiler front infrastructure .
