摘要/Abstract

摘要： 为弥补传统热工测量在精细工况分析方面的不足,论文结合典型生产案例,系统探讨了如何利用差热分析(DTA)、岩相分析、激光粒度分析等现代测试技术及计算流体力学(CFD)数值模拟分析技术来深度拓展水泥窑烧成系统运行工况的分析。分析结果表明:差热分析可通过煤粉燃烧过程中的失重峰和放热峰特征判定煤粉的燃烧特性、是否混煤及混煤效果;岩相分析可通过分析主要矿物相含量及结构缺陷,揭示熟料煅烧与冷却制度,以及原料品质等因素对熟料质量的不利影响;激光粒度分析可提供更加精确、全面的粒径特征参数,明确生料粒度对系统收尘效率的影响(如生料的中位粒径D₅₀过低,会导致C1预热器含尘浓度骤升);CFD数值模拟结果的精准性高度依赖于边界条件的设置,以正确的测试数据作为边界条件,能真实反映系统的运行状况,进而明晰供风不佳、涡旋耗能等问题对熟料冷却效率及热能利用率的潜在影响。通过深度剖析相关参数的变化规律,本文提出了优化工艺、热工制度及改进系统结构设计的解决思路,强调了先进测试和分析技术在提升系统热效率和运行稳定性中的重要价值。

Abstract: To address the limitations of traditional thermal measurement methods in detailed condition analysis, this paper integrated typical production cases to systematically explore the application of modern testing techniques—such as differential thermal analysis (DTA), petrographic analysis, and laser particle size analysis—as well as computational fluid dynamics (CFD) numerical simulation, in deeply expanding the analysis of the operating conditions of cement kiln sintering systems. The results indicate that DTA can determine the combustion characteristics of coal, the presence of coal blending, and its effectiveness based on characteristic mass loss and exothermic peaks during combustion. Petrographic analysis, through examination of major mineral phase content and structural defects, reveals the adverse impacts of sintering and cooling regimes, as well as raw material quality, on clinker quality. Laser particle size analysis provides more accurate and comprehensive particle size parameters, clarify the influence of raw meal particle size on the system's dust collection efficiency (for example, it can reveal that raw meal with an excessively low median diameter D₅₀ will cause a sharp increase in dust concentration of C1 preheater).The accuracy of CFD numerical simulation results is highly dependent on the setting of boundary conditions. Using correct test data as boundary conditions can realistically reflect the system's operational status, thereby clarifying the potential impacts of issues such as poor air supply and vortex energy dissipation on clinker cooling efficiency and thermal energy utilization rate. Through in-depth analysis of the variation patterns of relevant parameters, this paper proposes solutions to optimize the process, thermal regime, and improve the system's structural design, emphasizing the important value of advanced testing and analysis technologies in enhancing system thermal efficiency and operational stability.
