摘　　要：针对电站超临界机组锅炉吹管要求越来越高的问题,详细分析比较锅炉各种吹管方式的优劣,根据某厂DG3030/26.25-Ⅱ型锅炉特点以及现场条件,选择了一阶段稳压吹管方式;通过计算选择适当的吹管参数;设计临时补水系统;制定该机组吹管流程、吹管过程、吹管标准.可为各类机组提供借鉴.Considering the increasingly high requirements for pipe blowing of ultra-supercritical boilers in power plants, this paper analyzes and compares merits and demerits of different blowpipes in detail. One-stage stable pressure blowing method is chosen based＂ on the features of DG3030/26.25 - II boilers and its working conditions; appropriate blowing parameters are selected through calculation; temporary water-supplement system are designed, and blowing scheme, process, procedure and criteria for this unit are formulated. The design can cast light on units of all kinds.
