| 面对全球能源紧张与环境规制趋严的双重压力,水泥工业的燃料替代转型尤为迫切。本文以位于沙特阿拉伯北方边境省图赖夫市的一家日产5000吨熟料的水泥生产线为具体案例,研究其利用黑碳粉(Black Carbon)作为替代燃料,通过改造窑头燃烧器部分替代重油进行熟料煅烧的实践。项目于2024年3月启动改造,2024年6月正式投运,截至2025年12月已稳定运行18个月。论文系统阐述了项目背景与地域动因,分析了采用黑碳粉对保障当地能源安全、降低成本和履行环保责任的意义。重点论述了窑头燃烧器及配套系统的改造方案,评估了黑碳粉-重油混燃对煅烧过程、熟料质量及系统稳定性的影响。研究结果显示,在20%热值替代率下,吨熟料燃料成本下降12.3%,年减排化石CO₂约4.2万吨,投资回收期18个月。该项目在特定掺加比例下取得了良好的经济效益与环境效益,为资源匮乏的边境地区工业可持续发展提供了可行的技术路径,并对未来优化方向提出了建议。 |

| Facing the dual pressure of global energy tension and increasingly strict environmental regulations, the fuel substitution transformation of the cement industry is particularly urgent. This paper takes a cement plant in Turayf City, Northern Border Province, Saudi Arabia as a case study to investigate the practice of using Black Carbon as an alternative fuel to partially replace heavy oil for clinker calcination through kiln head burner modification. The project started renovation in March 2024 and was officially commissioned in June 2024, and has been running stably for 18 months as of December 2025. The paper systematically expounds the project background and regional motivation, and analyzes the significance of using black carbon powder to ensure local energy security, reduce costs and fulfill environmental responsibilities. The modification scheme of kiln head burner and supporting system is discussed, and the influence of black carbon powder-heavy oil mixed combustion on calcination process, clinker quality and system stability is evaluated. The results show that at 20% heat value substitution rate, the fuel cost per ton of clinker decreased by 12.3%, the annual fossil CO₂ emission reduction was about 42,000 tons, and the investment payback period was 18 months. The project has achieved good economic and environmental benefits at a specific blending ratio, providing a feasible technical path for the sustainable development of industry in resource-scarce border areas, and putting forward suggestions for future optimization. |
