| Abstract: | There are crazes and leakage in welding lines in back-elbow of back-pipelines of spray type desuperheater outlet between low-temperature reheater and high-temperature reheater of No.3 boiler in a power plant.By testing and calculation on spray type desuperheater,reasons for leakage are analyzed in terms of adjusting means of reheat steam temperature,welding process of pipelines and so on.It is indicated that there are unreasonable structural design of spray type desuperheater,adjusting means of reheat tempe... |
