Frequently Asked Questions
For higher boiler loads, optimizing flame scanner performance begins with proper installation and is further enhanced when a fiber optic cable is installed with an appropriate degree bend at the tip specification.
2. What is the industry standard operating temperature range for an IR or UV scanner?There is no industry standard on the temperature range, but the majority of our competitors have an operating temperature range between 120°F and 150°F. Safe-Fire’s flame scanner has the highest operating temperature range in the industry at 212°F.
3. What is a typical setting for cooling air flow to the scanners?Cooling air flow to the scanners is based on the total number of flame scanners in the system, diameter of the pipe and length of the pipe. The correct sizing of the blower is also a factor. Typically the air flow pressure at each scanner, without a fiber optic cable, needs to be at 6” w.c. above furnace or windbox pressure or a volume of 6 SCFM. If each flame scanner has a fiber optic cable it will require a pressure setting at 10” w.c. above furnace or windbox pressure or a volume of 15 SCFM.
4. If cooling air jackets are required for each flame scanner, can you use plant air?Plant air will not generate enough pressure that is required for cooling air jackets. A compressor is required to supply the air required to the cooling air jackets only. The compressor cannot be used on any other equipment.
