Abstract
PURPOSE:To adjust a transmitting light quantity to an image pickup device housed in a water-cooled lance, by adjusting the light quantity in a furnace transmitting to an image pickup means in accordance with the luminance of a furnace wall using a light quantity adjusting element with an impressed voltage. CONSTITUTION:A measuring truck 3 is stopped at the upper position of a combustion chamber 42 to be an observation object, and a water-cooled lance elevating mechanism 31 in front of the truck 3 lowers a water-cooled lance 1 from an inspection port 44 of the combustion chamber 42 inward the combustion chamber 42 down to an appropriate depth. A high-temperature furnace wall surface observing device 2 built-in the lance 1 image picks up the wall surface of the combustion chamber 42 by using the light in the furnace, sends the picture to the truck 3, and observes a wall surface condition. When the luminance on the wall surface changes due to the change of the temperature in the furnace, a light quantity adjusting element 24 is remote-controlled while the screen of the truck 3 is observed, and by changing the impressed voltage value, the transmitting light quantity to a TV camera 21 is adjusted.
