Abstract
A flare monitoring apparatus for detecting the generation of black smoke in a flare, the excessiveness of a flare and extinguishment of a flare based on the ratio and/or difference between an emissive power of infrared radiation emitted from a flare at a wave length at which a peak of the emissive power due to a resonance infrared radiation of a specified gas contained in a flue gas exists and an emissive power of infrared radiation emitted from the flare at another wave length at which a peak of the emissive power due to a resonance radiation does not exist. The apparatus produces an alarm and automatically controls the state of the flare upon the detection of the abnormality of the flare.
