摘要

某电厂300MW亚临界鼓式炉在运行维护过程中，发现其防腐水平较差，水冷壁沉积率很高。通过电镜和能谱分析了水冷壁管和省煤器管的沉积情况，分析了水冷壁管沉积率高的原因，并提出了相应的对策。

Analysis and Countermeasure of High Deposition Rate of Boiler Water Cooling Wall of 300MW Subcritical Unit

During the operation and maintenance of a 300MW subcritical drum furnace in a power plant, the corrosion protection level was found to be poor, the deposition rate of water-cooled wall was very high. The deposition of water-cooled wall tube and economizer tube was analyzed by electron microscope and energy spectrum, the reason of high deposition rate of water-cooled wall was analyzed, and the corresponding countermeasures were put forward.
