ABB Uvisor SF810i Integrated Safe Flame Scanner
Overview
The ABB Uvisor SF810i Integrated Safe Flame Scanner is a Multi Fuel Safe Flame Scanner – not a stack gas analyzer – that combines the flame sensor and all signal-processing electronics into a single compact, cylindrical housing, providing complete burner flame-proving for combustion safety interlocks in one self-contained unit. Where a conventional split-architecture flame scanner requires a separate remote amplifier cabinet wired back to the sensing head, the SF810i’s integrated design eliminates that additional enclosure and field wiring run, simplifying installation on both new burner management system projects and retrofit upgrades.
As the officially authorized partner and exclusive regional representative for ABB in Oman and the GCC, Seven Star LLC proudly supplies the Uvisor SF810i to power generation and heavy-industrial combustion operators across the Sultanate of Oman and the wider Gulf region. Every unit is backed by genuine ABB manufacturer warranty, regional technical support, and application guidance for burner management system integration – the assurance that comes only from an authorized regional channel.
Detection Principle
The SF810i incorporates solid-state sensor modules covering the entire flame radiant spectrum from UV to IR, including a dual UV-IR sensor configuration housed within the single enclosure, detecting ultraviolet, visible, and infrared radiation from the flame simultaneously. Beyond simply confirming that a flame is present, the SF810i applies ABB’s proprietary Combustion Index technology to continuously assess combustion quality and detect fuel degradation – giving burner management systems and operators early insight into combustion problems developing well before they would trigger a simple flame-failure trip.
Flame status and Combustion Index data are transmitted over dual PROFIBUS DP-V1 interfaces at speeds up to 12 Mbit/s, giving redundant, high-speed digital communication to the burner management system or DCS rather than relying on a single point-to-point analog signal. This redundant digital architecture is a deliberate safety design choice: a communication path failure on one PROFIBUS interface does not take flame-proving data offline, keeping the safety interlock function available even during a partial communication fault.
Engineering Design of the ABB Uvisor SF810i
The SF810i is built around a fail-to-safe design philosophy consistent with burner management system safety requirements, and is rated ATEX II 2GD Ex d IIC T6 for explosion-proof installation in hazardous combustion areas, with an IP66/67-rated enclosure and screw-type removable terminals plus quick-release connectors for straightforward field wiring and maintenance access. The instrument is engineered for multi-fuel applications across industrial and utility boilers, supporting both wall-fired burner configurations and corner-fired tilting burner installations where the scanner’s line of sight to the flame changes as the burner tilts.
For wall-fired burners, the SF810i is typically installed with a direct line-of-sight mounting arrangement; for corner-fired tilting burner applications, a fiber optic cable configuration with cooling provisions carries the flame’s optical signal back to the scanner body, protecting the sensing element from the direct radiant heat and mechanical movement at the tilting burner nozzle. The scanner is designed to integrate directly with ABB’s Symphony Plus control architecture, giving plants standardized on ABB’s DCS platform native scalability, CPU power, and communication speed for flame-proving data alongside the rest of the combustion control system.
Key Features
The Uvisor SF810i combines integrated construction with advanced combustion diagnostics, including:
- Fully integrated design – sensor and electronics in one enclosure, eliminating a separate remote amplifier cabinet.
- Solid-state UV-IR dual sensor spectrum coverage for reliable flame detection across liquid, gaseous, fossil, and synthetic fuels.
- ABB Combustion Index technology, assessing combustion quality and fuel degradation beyond simple flame presence.
- Dual redundant PROFIBUS DP-V1 communication at up to 12 Mbit/s to the burner management system or DCS.
- ATEX II 2GD Ex d IIC T6 explosion-proof rating for hazardous area installation.
- IP66/67-rated enclosure with screw-type removable terminals and quick-release connectors.
- Fail-to-safe design philosophy consistent with burner management system safety requirements.
- Native integration with ABB Symphony Plus DCS architecture, plus line-of-sight or fiber optic mounting for wall-fired and tilting burner configurations.
Industrial Applications
Reliable flame proving is a life-safety function in any fired equipment, and it carries particular weight across Oman and the GCC’s power generation and heavy-industrial combustion facilities running large utility and industrial boilers on multiple fuel types. In power generation, the SF810i is installed on wall-fired and corner-fired tilting burners to provide continuous flame-proving to the burner management system, with its Combustion Index data giving plant operators additional visibility into combustion quality that a simple flame-present/flame-absent scanner cannot provide. In refining and heavy-industrial combustion applications burning liquid, gaseous, fossil, or synthetic fuels – or combinations of these – the same integrated scanner design simplifies installation and reduces the field wiring burden compared to a split remote-amplifier architecture.
As the officially authorized partner for ABB in Oman and the GCC, Seven Star LLC distributes the Uvisor SF810i to power utilities, refineries, and EPC contractors across Muscat, Sohar, and Salalah, as well as the wider Gulf region. Because it is designed for both new burner management system projects and retrofit upgrades of existing flame-scanning infrastructure, it fits equally well into a greenfield boiler specification or a life-extension project on an operating unit.
