Application Scenarios

In a large coal-fired power plant operating multiple burners with low-NOx emission targets, flame discrimination challenges led to nuisance trips and unreliable burner management. The installation of the Fireye 45RM4-1001 enabled plant operators to dial in the ideal flame flicker frequency for pulverized coal combustion, effectively distinguishing target burner flames from adjacent burner radiation and furnace background glow. The scanner’s 10-LED bargraph simplified alignment, reducing commissioning time by over 50%.

For natural gas-fired industrial boilers, the Fireye 45RM4-1001 detects the mid-range flicker frequencies typical of gas flames while rejecting background infrared radiation from refractory walls. Its self-checking electronic shutter allows the associated Fireye amplifier to verify scanner integrity every cycle, ensuring that a failed component does not produce a false “flame present” signal. The Fireye 45RM4-1001 is also widely deployed in chemical plants and refineries, where its 24VDC operation minimizes electrical noise interference common with AC-powered scanners, ensuring stable flame relay operation even in high-electromagnetic-interference environments.
