| Abstract: | This work analyzes the issues that appeared after axial fan transducer reconstruction in one 1000 MW ultra-supercritical once-through boiler. The change of the fan characteristics and the problems associated with thermal control logic are introduced respectively. To solve these problems, we firstly analyze the obtained test data and then propose several measures to ensure the safety and economy of the fan. Meanwhile, this paper also aims to supply certain re ference for similar fans. |
