摘　　要：近年来,随着经济快速发展,工业成为全球产业的发展重心。在这个多样化的工业环境中,高炉炼铁作为关键的生产环节取得了显著进步,而热风炉作为关键设备也得到了广泛的应用。这一进步填补了国内技术上的短板,为我国工业发展注入了新的活力。然而,尽管取得了巨大的成就,在节能方面仍有提升的空间。技术人员需要不断努力,以降低能耗、提高热效率,同时注重环保和设备的长寿,确保能源利用高效。这样不仅可以节约能耗,还可以使工业生产更加环保和可持续。以内燃式热风炉作为分析对象,讨论热风炉结构,对热风炉三维稳定态流体力学模型的基本假设、模型计算域、网格划分、边界条件以及控制方程进行探讨,并分析模型的模拟结果,希望通过内部流动与传热特性的探讨提高热风炉的热效率,提升生产过程中的能源利用效率,降低生产成本。In recent years,with rapid economic development,industry has become the centre of gravity of global industry.In this diverse industrial environment,blast furnace ironmaking has made remarkable progress as a key production link,and hot blast furnace has been widely used as its key equipment.This progress has flled the shortcomings in domestic technology and injected new vigour into China's industrial development.However,despite the great achievements,there is still room for improvement in energy saving.Technicians need to make continuous efforts to reduce energy consumption and improve thermal efficiency,while focusing on environmental protection and equipment longevity to ensure efficient energy use.This wil not only save energy consumption,but also make industrial production more environmentally friendly and sustainable.It takes the internal combustion hot air furnace as the object of analysis,discusses the structure of the hot air furnace,discusses the basic assumptions of the three-dimensional steady state hydrodynamic model of the hot air furnace,the model computational domain,mesh division,boundary conditions,and the control equations,and analyses the simulation results of the model,hoping to improve the thermal efficiency of the hot air furnace through the exploration of the internal flow and heat transfer characteristics to improve the efficiency of the use of energy in the production process and to reduce the cost of production.
