摘　　要：针对1000 MW燃煤机组电除尘器的运行特性,结合双套管气力输灰技术,对不同输灰系统设计及运行调试中出现问题进行了比较,提出了管道出力、系统出力、输送罐出力的概念。根据运行实践,将1000 MW燃煤锅炉机组电除尘器输灰系统归纳为两种典型设计,可使输灰系统的配置设计日趋标准化。In the light of the operation features of electric precipitator in 1000MW fossil-fired unit and combined with dual-tube socket technology,the problems occurred in different ash conveying systems and operations have been compared,and the pipeline capacity,system capacity and transfer tank capacity have been put forward in the paper.According to the practice,two typical designs of electric precipitator dry ash conveying system in 1000MW coal-fired unit have been generalized,which will make the ash conveying system standardized.
