摘要
An optical fiber is laid in a spiral shape on a surface of an iron skin of a hot-air oven constituting a blast furnace facility, and one end of the optical fiber is connected to a temperature measuring apparatus. A temperature distribution of an optical fiber laid area is measured based on the intensity of Raman back scattering light of a light pulse transmitted into the optical fiber and based on a time interval until the Raman back scattering light returns to the transmission end of the optical fiber. The temperature distribution is displayed on a display screen to monitor the temperature distribution of the whole area of the iron skin of the hot-air oven to detect an abnormal condition thereof.
