| 摘 要： | 以加热炉中烟气出口处蓄热体为研究对象,建立了一维非稳态导热过程的数学模型,采用有限差分法进行模型的离散化.使用C 语言开发了计算球体蓄热体热饱和时间的程序,确定了蓄热体热饱和时间与各种影响因素之间的关系.结果表明,对流换热系数的增加会缩短蓄热体的热饱和时间,而蓄热体热容、密度及其半径的增加均使得蓄热体的热饱和时间线性增加.

| Abstract: | The regenerator in the outlet of a reheating furnace was studied. A one-dimensional unsteady state model was set up and got discretization through finite difference method. A program of computing the heat saturating time of the solid sphere regenerator was developed by C language. The relationship between the heat saturating time and the factors which influence the time was determined. It is shown that the heat saturating time decreased when the heat convection coefficient increased; whereas the increase of heat capacity, density and diameter of regenerator made the heat saturating time increase linearly. |
