Flame monitors play a critical role in ensuring safety in combustion plants by detecting the presence of a flame in the burner and preventing hazardous accumulation of fuel in the combustion chamber in case of an unexpected flame outage. Continuous monitoring of the flame is imperative for plant operators to prevent potential explosions.
Our optical flame monitors utilize continuous monitoring and measurement of flame radiation to effectively monitor flames without interference. They analyze the average intensity or fluctuation strength of radiation in various spectral ranges such as ultraviolet, visible or infrared, and differentiate signals from similar flames in multi-burner plants by comparing them to a threshold value defined during installation. This makes them reliable and safe for monitoring flames in high-performance burners with varying fuels. On the other hand, our ionization flame monitors utilize a metallic ionization electrode that needs to be immersed in the flame to establish an electrically conductive connection with the burner or ignition burner mechanism. They measure the ionization direct current signal in the flame monitor and make a "Flame ON / OFF" decision based on it. Ionization flame monitors are highly selective and widely used in ignition and pilot burners.
FLAME MONITORING - IONIZATION
Our ionization flame monitors monitor the flame effectively and without interference using a metallic ionization electrode that must be immersed in the flame. The burning flame establishes an electrically conductive connection between the ionization electrode and the burner or ignition burner mechanism as ground potential. At the same time, the electrically conductive flame acts as a rectifier for the ionization current. This ionization direct current signal is measured in the flame monitor and used for the “Flame ON / OFF” decision. Ionization flame monitors are characterized by excellent spatial selectivity and are used in the vast majority of ignition and pilot burners.
FLAME MONITORING - OPTICAL
Our optical flame monitors monitor the flame effectively and without interference by continuously monitoring and measuring the flame radiation. Depending on the variant, they analyze the average intensity of radiation or the strength of its fluctuation in the ultraviolet, visible or infrared spectral ranges, or several of these ranges, for the properties typical of the flame. A comparison with a threshold value defined during installation and the selection of a spectral range optimized for the flame radiation allow differentiation from the signals of similar flames in a multi-burner plant. Optical flame monitors also monitor the flames in high-performance burners and with changing fuels absolutely reliably and safely.
