Description of the Related Art Fuel tanks and oil tanks of thermal power plants are required to be inspected and inspected at predetermined intervals (5 to 10 years) according to the Fire Service Law. The tank is composed of a welded structure of a fixed-size steel plate of a predetermined size. When inspecting the bottom plate weld line of the tank, it is necessary to remove the coating such as tar epoxy paint or glass flake paint applied to the inner surface from the weld line portion. Further, when the deterioration of the coating film is remarkable, the coating film on the entire bottom surface must be removed. After the inspection, a new paint of the same kind is applied, and fuel oil such as crude oil and heavy oil is stored in the tank.

え、その改善が切望されていた。At present, a sand blasting method is mainly used as a method for removing the coating film. This conventional method has the following problems. Since it was a manual operation, the polishing quality was poor due to uneven polishing. Also, continuous work was sometimes difficult, and the cleaning ability was low. Furthermore, since sand is used, the working environment is poor and an enormous amount of industrial waste is generated. Therefore, environmental problems, which have been highlighted recently, have been eagerly sought.
