Beschreibung
Zusammenfassung:	A device for estimating an outer surface temperature of a radiant coil which is provided in an cracking furnace for ethylene production including a convection coil that preheats hydrocarbons as raw materials and steam, a radiant coil that thermally decomposes the preheated hydrocarbons and steam, and a housing for accommodating them, and which includes an imaging camera that images a region to be imaged of the radiant coil, and an image analyzer that processes an output signal from the imaging camera and estimates an outer surface temperature of the radiant coil.
