Abstract: The reasons of leakage at welding seam of reheater tubes supports of 660MW unit in Hanfeng Power Plant of China Huaneng Group were analyzed. A reformation scheme was proposed and adopted, which advocates change the fixed support structure into movable support structure. After reformation, the leakage was not occurred again.
Key words: reheater, leakage, additional stress, reheating crack
