| 摘 要： | 以135 MW循环流化床锅炉的防磨损技术改造为背景,分析了循环流化床锅炉炉内受热面的磨损机理。针对炉膛内固体颗粒高速流动、由于突起而形成涡流等引起磨损的原因,分别提出了喷涂防磨涂层、水冷壁结构优化设计、保证受热面光滑等防磨措施。运行实践证明,采取上述措施,使受热面的磨损情况得到了有效的控制。 |
| 关 键 词： | 循环流化床锅炉 磨损机理 受热面 |

| Abstract: | Based on the abrasion-resistant retrofit for the 135 MW CFB boiler,the abrasion mechanism of the furnace heat-absorbing surfaces in CFB boilers is analyzed.To solve the problem that the high-speed particles in the furnace tend to create eddy current when meeting with protuberances and cause abrasion consequently,countermeasures such as spraying abrasion-resistant coating,optimizing water wall structure,ensuring heat-absorbing surfaces smooth are proposed.Practice shows that these measures are effective. |
| Keywords: | CFB boiler abrasion mechanism heat-absorbing surface |
