摘要: |
火电厂锅炉水冷壁管高温腐蚀和磨损与炉膛火焰温度、燃煤的含硫量、烟气与灰粉颗粒的冲蚀密切相关。采用高速电弧喷涂技术,喷涂SCZ16合金,对燃煤含硫量高的锅炉水冷壁管进行表面处理获得了良好的效果,并在多个电厂中推广应用。 |

Abstract: |
The wear and corrosion at high temperature of cooling tubes for the power plant boils are closely related with flame temperature in chamber of furnace, sulphur content of coal, and erosion of ash particles. A good result was obtained using high speed arc-sparing technique of SCZ16 alloy on the cooling tubes. This technique has been successfully popularized in a number of power plants. |
Key words: cooling wall of boiler,wear and corrosion at high temperature,high speed arc spraying, |
