| 摘 要： | 循环流化床锅炉机组因其具有的优良特点适应中国国情而得到了迅速发展，但与煤粉锅炉相比，其特殊的燃烧方式使其必须采用高压头的一次风机与二次风机，造成流化床锅炉电站厂用电率较高。为了提高某135 MW循环流化床锅炉二次风机的效率，对该风机进行了技术改造，即通过在该风机原有叶片中间增加小叶片的方式来提升其效率。改造前后风机性能测试数据表明，改造后风机的流量与效率提升明显，其转速越低，风机性能提高幅度越大。

| Abstract: | The CFB boiler is developed rapidly due to its outstanding characteristics suitable to the circumstances in China. However, compared to the pulverized coal boiler, its special combustion style makes it necessary to adopt the high-pressure primary and secondary air fans, which leads to high auxiliary power consumption rate. In order to improve the efficiency of the secondary air fan of a 135-MW circulating fluidized bed (CFB) boiler, the technical retrofit is conducted on the fan by installing small blades between the original blades to enhance its efficiency. The comparison between the fan performance test data before and after the retrofit shows that the flow and the efficiency are improved significantly after the retrofit; the lower the speed is, the larger margin of the fan performance is achieved. |
