摘要
准确了解单侧加热燃气退火炉内的传热过程对优化其热工制度具有重要意义.通过建立单侧加热燃气退火炉的数学模型,模拟计算单侧加热燃气退火炉内的气体流动、换热过程,探究空气过量系数、排烟方式对炉内温度分布的影响.结果表明:炉内沿高度方向温度分层现象明显,选择合理空气过剩系数,增设上排烟口,可改善炉内温度分布;炉内温度模拟值与试验值相对误差低于10%,可为单侧加热燃气退火炉开发设计提供参考.
Abstract
Accurately understanding the heat transfer proces s inside a single-sided heating gas annealing furnace is of great significance for optimizing its thermal regime.By establishing a mathematical model of a single-sided heating gas annealing furnace,the gas flow and heat transfer process inside the furnace are simulated and calculated,and the influences of air excess coefficient and exhaust method on the temperature distribution inside the furnace are explored.The results show that there is a significant temperature stratification phenomenon along the height direction inside the furnace.Choosing a reasonable excess air coefficient and adding an upper exhaust outlet can improve the distribution of temperature inside the furnace.The relative error between simulated and experimental values of the furnace temperature is less than 10%,which can provide reference for the development and design of single-sided heating gas annealing furnaces.
