摘要

为了研究双蒸汽蓄热器系统的动态特性，采用集总参数法建立相应的数学模型，进行直接交替和间接交替两种充汽方式的动态仿真。仿真结果表明：直接交替充汽方式充汽时间减少2.6 s，压力波动更小；相同充汽方式下，汽包压力波动 < 过热蒸汽压力波动 < 供汽母管压力波动；直接交替充汽方式燃油量节省率为7.45%。通过数据对比分析可得：直接交替充汽方式具有充汽速度快、压力波动小、燃油经济性好的优点。

Abstract

To study the dynamic characteristics of double steam accumulators system.The mathematical models are based on the lumped parameter theory.The study has been carried out two different charging ways.One of them is the direct alternate and the other is the indirect alternate.The simulation results show as follows.The direct alternate charging way than the indirect alternate charging way less time 2.6 s.The pressure fluctuation of the direct alternate charging way is less than the pressure fluctuation of the indirect alternate charging way.In the same charging way

the fluctuation of drum pressure is less than the fluctuation of superheated steam pressure

and the fluctuation of superheated steam pressure is less than the fluctuation of steam supplying pipe pressure.The direct alternate charging way than the indirect alternate charging way fuel oil saving rate is 7.45%.Through data analysis can know.The advantage of the direct alternate charging way is charging faster and pressure fluctuation smaller and less fuel oil consumption.
