交替充汽方式下双蒸汽蓄热器系统动态特性仿真
Dynamic characteristics simulation of double steam accumulators system under alternate charging ways
摘要
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 7.4 5 %.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.关键词
