摘　　要：一直以来,工业企业在全球能源消耗中占据着举足轻重的地位。作为这些企业的核心设备之一,热风炉在工业生产中发挥着无可替代的作用。热风炉既是能源消耗的主体,也是工业生产过程中不可或缺的热量提供者。热风炉的工作原理主要是利用燃料燃烧产生的热量,通过热交换器将热量传递给空气,产生高温热风。这些高温热风在工业生产中广泛应用于各种工艺流程,如烘干、烧结、熔炼等,对于提高生产效率和产品质量具有至关重要的作用。在介绍顶燃式热风炉燃烧器结构的基础上,探讨顶燃式热风炉数值模拟现状,重点分析了顶燃式热风炉燃烧几何模型和数学模型,并从速度分布以及温度场分布对数学模拟结果进行分析,望能通过优化燃烧过程,可以提高热风炉的燃烧效率,降低燃料消耗量和能源成本。For a long time,industrial enterprises occupy a pivotal position in global energy consumption.As one of the core equipment of these enterprises,hot blast stove plays an irreplaceable role in industrial production.Hot blast stove is not only the main body of energy consumption,but also an indispensable heat provider in the industrial production process.The working principle of hot blast stove is mainly to use the heat generated by fuel combustion,and transfer the heat to the air through the heat exchanger to produce high temperature hot air.These high temperature hot air are widely used in various processes in industrial production,such as drying,sintering,melting,etc.,which plays a vital role in improving production efficiency and product quality.Based on the introduction of the burner structure of the top-burning hot blast stove,it discusses the current situation of numerical simulation of the top-burning hot blast stove,focuses on the analysis of the combustion geometric model and mathematical model of the top-burning hot blast stove,and analyzes the mathematical simulation results from the velocity distribution and temperature field distribution,hoping to improve the combustion efficiency of the hot blast stove by optimizing the combustion process.Reduce fuel consumption and energy costs.
