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.
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 operates well above that with the highest operating temperature level in the industry at 185°F.
Cooling airflow 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 airflow 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.
Plant air will not generate enough pressure to adequately cool 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.
