Hot blaststove reactor introspective observing/thinking device

摘要

PURPOSE: To observe and pick up the damage state of refractories in a furnace simply and quickly by a method wherein a photoelectric multiplier and a remotely-controllable zoom device are connected sequentially to the fore part of a pickup tube and the like while the whole of the devices is accommodated in a cooling box having a window glass reflecting infrared rays of specified wavelength. ;CONSTITUTION: A photomultiplier 11 is connected to the fore part of a pickup tube or a pickup element 10 while a remotely-controllable zoom device 13, having a lense 12 provided with the degree of transmission suitable for a spectral sensitivity is connected to the fore part of the photoelectric multiplier 11 whereby an image pickup device 14 is constituted. On the other hand, the whole of the image pickup device 14 is accommodated in a cooling box 16, having a window glass 20 reflecting infrared rays of wavelength of 2μm or more, whereby an observation device is constituted. Further, the control rod 17 of the observation device is provided with a handle for swinging the whole of the cooling box 16 horizontally and another control rod oscillating the same forward-and-rearward respectively. By this method, infrared rays from the wall surface of refractory in a furnace are observed as the amount of light without employing any other illuminating device and without being affected by the value of the distance.;COPYRIGHT: (C)1993,JPO&Japio
