摘要
本文利用Fluent商业软件模拟并优化了基于Aspen软件设计的热风炉节点参数。采用三维非预混PDF燃烧模型,封闭的Standard k-ε湍流模型方程,P-1辐射模型计算了炉内的气体化学燃烧反应。通过模拟计算了初始烧坏燃烧器的炉子流场,借此以改善配风及炉体结构,优化了热风炉出口温度及氧浓度。结果表明优化后的温度场更加有利于设备和后续工艺的长期运行,优化后的氧浓度场更加有利于后续工艺的运行。
The paper has researched and optimizated the node parameters of a hot blast stove based on theAspen design by the business software of Fluent. The paper has used the 3 D non - premixed PDF com-bustion model, closed Standard k - e turbulent moedel and P - 1 radiant model to calculate the chemicalreaction of the gas combustion. At first, the paper has calculated the flow field of the blast stove that theburner had burned - out, then improved the air distribution and the structure of the blast stove to optimi-zate the temperature and oxygen concentration field of furnace outlet. The results indicate that not onlythe optimizated temperature field more conductive for the equipment and the follow -up process to run,but also the optimizated oxygen concentration field more conducive for the follow -up process to run.
