摘　　要： 本文建立了超临界直流锅炉启动过程汽水膨胀的计算模型，并用试验进行了验证。利用该模型计算了哈尔滨锅炉厂开发设计的６００ＭＷ超临界直流锅炉冷态、热态启动过程的汽水膨胀，为锅炉启动系统设计及拟定启动曲线提供了依据。 A mathematical model is set up for calculating the water swell in a supercritical pressure once through boiler during its start up.The model has been verified through tests and was used to calculate the water swell during a cold state and hot state start up process in a 600 MW supercritical pressure once through boiler designed and developed by Harbin Boiler Works.All the above has provided a basis for the design of boiler start up systems and the drawing up of start up curves.

关 键 词： 超临界压力 直流锅炉 汽水膨胀 锅炉
