摘　　要：启动锅炉作为新建电厂辅助蒸汽系统的重要组成部分,主要有燃油锅炉和电极式蒸汽锅炉2种类型,对2类锅炉的技术特点、性能指标、应用实例进行了分析。目前,采用电极式蒸汽锅炉是发电厂辅助蒸汽系统设计的发展趋势。以某核电厂辅助蒸汽系统电极式蒸汽锅炉的电气接线设计为例,根据电锅炉的不同电压等级要求,提出了3个电气设计的比较方案,通过技术方案实施的可行性、运行维护的方便性、设备选择的灵活性、经济技术性能指标等方面进行了深入的分析与探讨,提出了电锅炉设计方案时应考虑的问题及建议,可供设计时参考。As an important part of auxiliary steam system in a new power plant, there are two types of start-up boiler, oil boiler and electrode boiler. According to the analysis of technical characters, performance and application, the steam electrode boiler is being used more and more. As an example of one nuclear power plant, according to the different voltage classes requirement of electrode boiler, three schemes of power supply on auxiliary steam electrode boiler were given, and the feasibility of technical proposal, the convenience of running and maintenance, the flexibility of equipment selection, and the technicality ＆ economy were discussed, and some questions and advices were put forward for consultation.
