摘　　要：应用质量守恒定律和能量守恒定律，导出了直流锅炉启动时除氧器水箱压力变化动态特性微分方程式，将其用于３００ＭＷ直流锅炉除氧器水箱压力飞升速度的仿真计算，并定量分析了影响压力飞升速度的主要因素．Based on the laal of mass conservation and energy conservation a differential equation of dynamic pressure response in deaerator tank during the start -up of an once through boiler is developed. The simulation calculation of pressure rise in deaerator tank of 300 MW once-through boiler is presented as an example and the main factors which effect on pressure change are analyzed quantitatively.
