构建低碳工业园区、促进能源结构转型、提高绿色生产水平是我国工业高质量发展的关键路径，低碳工业园区内源端可再生能源电力、荷端工业生产的蒸汽用量均呈现频繁的波动性，在低成本、大规模、长周期的储能技术全面工业化应用之前，预热燃烧锅炉具有承担源荷两端波动性调节的良好潜能。本文厘清了低碳工业园区用能趋势、预热燃烧锅炉的技术特征、低碳工业园区预热燃烧锅炉应用的适配性，梳理了预热燃烧锅炉的技术进展与发展方向，总结了我国预热燃烧锅炉的应用示范情况。开发的60 t/h煤粉预热燃烧锅炉实现10%~100%超宽负荷范围的灵活调节，开发的90 t/h煤粉预热燃烧锅炉实现压火46 h无辅助燃料的快速启动，开发的240 t/h循环流化床耦合煤粉预热燃烧锅炉实现化石能源和光伏电力的高效协同出力。后续，在生物质预热燃烧锅炉、预热燃烧锅炉氢氨掺烧或纯烧、锅炉启停与绿热供应协同、煤粉O₂/CO₂预热燃烧等方面实施技术攻关，以系统提升预热燃烧锅炉技术水平，全面支持零碳工业园区建设。

Constructing low-carbon industrial parks as well as promoting energy structure transformation and improving green production ability is critical for achieving high-quality development of China's industry. Within low-carbon industrial parks, both renewable energy power and steam consumption of industrial production exhibit frequent fluctuation. Before low-cost, large-scale, and long-period energy storage technologies are widely applied in the industry field, the preheating combustion boilers have the potential to balance fluctuation regulation. This study clarifies the energy using tendency in low-carbon industrial parks, technical characteristics of preheating combustion boilers, and adaptiveness of these boilers in industrial parks. Moreover, it reviews the technical progress and future development directions of preheating combustion boilers, and summarizes several demonstration projects implemented in China. The 60 t∙h^-1 pulverized-coal preheating combustion boiler has achieved flexible regulation within an ultra-wide load range of 10%‒100%; the 90 t∙h^-1 pulverized-coal preheating combustion boiler has realized rapid start-up without any auxiliary fuels after 46 hours of banked fire; and the 240 t∙h^-1 circulating fluidized bed boiler coupled with preheating combustion of pulverized coal has attained efficient, coordinated output of fossil energy and photovoltaic power. Future research should prioritize technological breakthroughs in biomass preheated combustion boilers, hydrogen and ammonia co-firing or pure combustion in preheating combustion boilers, coordination of boiler start-stop and green heat supply, as well as O₂/CO₂ preheating combustion of pulverized coal, aiming to enhance the technical capabilities of preheating combustion boilers and provide a comprehensive support for the development of zero-carbon industrial parks.
