摘要
针对某超高压135MW循环流化床锅炉一次风机变频改造后出现的"抢风"问题,在实际运行的冷态和热态工况下进行了诊断试验。根据诊断试验结果,提出了最优改造方案。对风机进行改造后问题得以解决。
To clear the " blower pinch " of the primary air fan after coversion reformation in a 135 MW super-high pressure CFB boiler, a related cold and thermal diagnostic test was carried out in the primary air fan under normal working condition. Besed on the test result, an optimum reformation sheme has been obtained. The problem was finally solved by taking appropriate retrofit.
