摘要

PROBLEM TO BE SOLVED: To provide a wall thinning cause investigating device capable of identifying the cause of wall thinning or perforation such as corrosion occurring in a water-cooled jacket, and a wall thinning cause investigation method using the device. SOLUTION: A metal container 11 for receiving water as a refrigerant, a water supply pipe 12 for supplying the water to the inside of the container 11, and water received in the container 11 are heated by a high temperature gas. It has a discharge pipe 13 for discharging hot water and / or steam, and in the container 11, the high temperature gas and water as a refrigerant come into contact with each other on the front and back surfaces, preferably on the high temperature side of a thick wall portion 11b. A plurality of types of spraying materials 14a to 14c are preferably provided in the region A of the surface of the surface, and no spraying material is provided in the region B.
