GAS FLUE INSPECTION DEVICE AND GAS FLUE INSPECTION METHOD

Japanese Patent JP2017020699

A

PROBLEM TO BE SOLVED: To improve an inspection accuracy of a deterioration state of an entire inner wall surface of a gas flue.SOLUTION: This invention relates to an inspection device 1 for inspecting a deterioration state at an inner wall surface of a gas flue F for use in guiding discharged gas generated at a furnace or a boiler and to a chimney and the like where there are provided a rear side viewing inspection probe 1A for inspecting a deterioration state of a top end part [a ceiling surface] in the gas flue F and a side viewing inspection probe 1B for inspecting a deterioration state at a side wall [a side surface] in the gas flue F. With this arrangement as above, since it is possible to inspect the deterioration state at each of the top end part and the side wall part in the gas flue F under the most suitable state for each of them, it is possible to improve an inspection accuracy of the deterioration state at the entire inner wall in the gas flue F. In addition, when the top end part in the gas flue F at one inspection position is inspected by the inspection probe 1A, the side wall part in the gas flue F is inspected by the inspection probe 1B at another inspection position, thereby it is possible to improve the inspection efficiency.SELECTED DRAWING: Figure 1
