摘要
在考虑蓄热体沿气体流动方向热传导,并将空气、烟气流动中对蓄热体的传热,看做气柱微元及蓄热体微元的体积内热源情况下,建立了蓄热体数学模型。采用有限差分方法对控制方程进行离散化,对蓄热体热过程进行了数值模拟。分析了材料物性及热工操作等参数对蓄热体工作的影响,对蓄热式加热炉蓄热体的选择提供了理论参考。
The regenerator mathematical model has been developed in this paper by considering the heat conduction in regenerator along the direction of gas flow and seeing heat transfer between regenerator and smoke and air as internal heat source of gas and regenerator. Governing equations is discredited by using finite difference method and numerical simulation on thermal process of regenerator is performed. Material physical parameters and thermal operating parameters effects on regenerator are analyzed. The results provide an important theoretical reference for regenerator selection of regenerative reheating furnace.
