Fireye Flame Scanners and Burner Management in Azerbaijan

Most fired equipment accidents happen during start-up or after a flame goes out unnoticed. The job of a flame safeguard system is simple to state: never let fuel flow into a furnace unless a flame is proven, and shut it off within seconds if the flame disappears. Fireye, based in New Hampshire, USA, has built flame scanners and burner controls for that job for decades, for boilers, process heaters and furnaces in industry and power generation.

ZE-Tronics supplies Fireye equipment in Azerbaijan and supports it on site — from choosing the scanner to setting up the flame signal during commissioning.

Fireye flame scanners

A flame scanner looks into the furnace and reports whether its burner is alight. Fireye offers UV and IR scanners in several series. In our catalogue you will find the InSight Series 4 (95S4UV and 95IRS4) and the Phoenix Series 2 (85UV and 85IR).

• UV scanners see the ultraviolet radiation of the flame and are widely used on gas firing.
• IR scanners respond to the flicker of the flame and are common with oil and solid fuels.
• Self-checking designs test their own sensor at intervals, which is required on burners that run continuously.

On a multi-burner boiler or heater the real challenge is discrimination: each scanner must see its own flame and ignore the burners around it. That depends on sighting, the flame’s shape and the scanner’s settings as much as on the model.

Burner controls and combustion management

BurnerLogiX flame safeguard controls sequence the burner: purge, pilot ignition, main flame proving, running and safe shutdown. Nexus parallel-positioning controls set fuel and air to hold efficient, stable combustion. SureFire II igniters and pilots complete the start-up chain. Where burner management forms part of a safety instrumented system, we design the interface with the plant’s safety logic and the DCS through our ICSS integration work.

How we support Fireye users

• Selecting and sighting scanners for each burner and fuel
• Reviewing start-up and shutdown logic against NFPA 85, NFPA 86 or EN 298 / EN 746-2, as applicable
• Commissioning, including flame signal set-up and trial-for-ignition tests
• Diagnosing nuisance trips, which are often caused by lens fouling, cooling-air problems or thresholds rather than the scanner itself
• Planned maintenance and replacement of obsolete controls
