锅炉启停过程中汽包壁温度场的数值计算

Numerical Calculation Of Boiler Drum Wall Temperature For Starting Process And Stoping Process

本文建立了锅炉启停过程中汽包壁温的数学模型，并采用有限差分法对自然循环锅炉的汽包在不同启停速度下壁内的温度分布作了数值计算，通过计算得出在不同的升温和降温速度下汽包壁内的温度分布。

In this paper,a mathematical model of boiler drum wall temperature for starting process and stoping process is created. By using finite-differernce method, the author pre dicted the distribution of the boiler drum wall temperature. The start-stop velocity effect on the boiler drum wall temperature is analyzed.
