Claims

[Scope of utility model registration request]

A large number of double pipes consisting of an inner heat transfer tube and an outer heat transfer tube surrounding the inner heat transfer tube are arranged side by side, and heat exchange is performed between the fluid inside the inner heat transfer tube and the fluid outside the outer heat transfer tube. In the heat exchanger, the lower end of the heat transfer inner tube is connected to the annular water supply inlet ring header installed in the shell, the upper end of the heat transfer inner tube is connected to the steam outlet ring header, and the heat transfer inner tube is connected to the steam outlet ring header. The outer heat transfer pipe is connected to the jacket ring header surrounding the jacket, and the detection space formed between the inner heat transfer pipe and the outer pipe is connected between the jacket ring header and the steam outlet ring header. A steam generator characterized in that the steam generator is connected to a leakage gas chamber defined in the steam generator.
