摘　　要：通过对超临界直流锅炉分类及特点的论述,详细介绍了带循环泵、扩容器和启动疏水热交换器 3 种内置式启动系统,以及与之关系密切的汽轮机旁路系统,同时强调具体的启动系统布置型式要综合考虑投资和电厂将来运行模式之间的关系。The sorts and technical characters of the supercritical strait boiler are introduced. Three start-up systems, with recycle pump, flash tank and drain heater exchanger for start-up are analyzed, and the by-pass system is presented. Besides, it’s stressed that the disposal of the start-up system must be considered through the investment and the running mode of the power station.
