摘要： To provide a position determining method and a work result management device, used for internal inspection of a space surrounded by surfaces such as a boiler furnace, and further used for inspection of an inner or outer wall in a vessel and capable of detecting plural positions. There is provided a method of determining a position where work is done in a space surrounded by surfaces, wherein the position where work inside the space is done is a sidewall, wave receivers capable of receiving an acoustic wave signal are placed at three or more points, which are on the same plane substantially parallel to the sidewall but not collinear with one another and whose position coordinates are known, the signal is transmitted from a wave transmitter capable of transmitting an acoustic wave and placed at a position where work is done on the sidewall in the space, and the respective arrival times of the signal at the three or more wave receivers that are not collinear with one another are measured to determine the position coordinates of the wave transmitter using the arrival times and the position coordinates of the three or more wave receivers.

摘要： An inspection device and an inspection method for boiler furnace water wall tubes. The inspection device includes a scanner including columns placed upright and fixed by magnets onto the surfaces of multiple water wall tubes extending in the up-down direction on the inner wall surfaces of the boiler furnace, a support frame fixed to the columns to support a displacement sensor producing laser light to be irradiated onto the surface of a water wall tube, and a moving mechanism for moving the displacement sensor in the axial direction of the water wall tube relative to the support frame. A signal processing unit calculates the amount of reduced wall thickness of the water wall tube from a difference between the cross-sectional surface shape of the water wall tube based on a signal from the displacement sensor and a reference shape without reduction in wall thickness.

摘要： There are provided an inspection device and an inspection method for boiler furnace water wall tubes, which can inspect reduced wall thickness conditions of multiple water wall tubes, extending in an up-down direction along inner wall surfaces of a boiler furnace and arranged adjacent to each other, accurately and efficiently over a wide range based on surface shapes of the water wall tubes measured by a laser displacement sensor. A scanner 14 including columns 20 placed upright and fixed by magnets onto the surfaces of multiple water wall tubes 4 extending the up-down direction on the inner wall surfaces of the boiler furnace, a support frame 28 fixed to the columns 20 to support a displacement sensor 12 producing laser light to be irradiated onto the surface of a water wall tube 4, and a moving mechanism 31 for moving the displacement sensor 12 in the axial direction of the water wall tube 4 relative to the support frame 28. A signal processing unit 16 is also provided for calculating the amount of reduced wall thickness of the water wall tube 4 from a difference between the cross-sectional surface shape of the water wall tube 4 based on a signal from the displacement sensor 12 and a reference shape without reduction in wall thickness in order to evaluate a reduced wall thickness condition.
