本数据集涵盖2022年12月-2025年11月在华中科技大学煤燃烧与低碳利用全国重点实验室完成的600 MW级旋流对冲锅炉全炉膛变负荷CFD模拟结果、600 MW级旋流对冲锅炉超低负荷下稳燃策略（不同燃烧器运行数量）CFD模拟结果及预燃室燃烧器锅炉全炉膛变负荷CFD模拟结果，并统计了锅炉稳燃表征量化指标的相关数据，包括600MW级旋流对冲锅炉不同负荷沿炉膛高度温度、600MW级旋流对冲锅炉不同负荷稳燃指标统计、不同稳燃策略下主燃区局部区域体积平均温度和平均温度比、预燃室燃烧器锅炉不同负荷沿炉膛高度温度；预燃室燃烧器锅炉不同负荷稳燃指标统计。该数据集为自主研发所得，采用建模软件Gambit建立锅炉几何模型，CFD软件ANSYS Fluent对所建模型的网格进行无关性验证和工况模拟，利用Tecplot、Origin等软件绘制温度、速度等云图和锅炉燃烧典型区域热负荷水平曲线进行结果分析。数据揭示了锅炉燃烧失稳边界，支撑了燃煤锅炉超低负荷无油稳燃设计，数据总量为32,768 KB。This dataset covers full-furnace variable-load CFD simulation results of 600 MW-scale swirl impinging boilers, CFD simulation results of combustion stability maintenance strategies (different burner operating quantities) under ultra-low load conditions, and full-furnace variable-load CFD simulation results of pre-chamber burner boilers, which were completed at the State Key Laboratory of Coal Combustion and Low-Carbon Utilization, Huazhong University of Science and Technology from December 2022 to November 2025. It also includes relevant data of quantitative indicators for combustion stability characterization, including temperature distribution along the furnace height under different loads for 600 MW-scale swirl impinging boilers, statistics of combustion stability indicators under different loads for 600 MW-scale swirl impinging boilers, volume-averaged temperature and average temperature ratio in local areas of the main combustion zone under different stability maintenance strategies, temperature distribution along the furnace height under different loads for pre-chamber burner boilers, and statistics of combustion stability indicators under different loads for pre-chamber burner boilers. This dataset was independently developed. The boiler geometric model was established using the modeling software Gambit. The CFD software ANSYS Fluent was utilized to perform grid independence verification and operating condition simulations for the built model. Tecplot, Origin and other software were used to plot contour maps of temperature, velocity and other parameters, as well as heat load level curves of typical boiler combustion regions for result analysis. The data reveal the combustion instability boundary of the boiler, which supports the oil-free combustion stability design of coal-fired boilers under ultra-low loads. The total data volume is 32,768 KB.
