摘　　要：为推进煤电机组低碳化改造及生活垃圾高效处理,探讨了燃煤机组与生活垃圾耦合发电的技术路线.在研究分析各种耦合方案的基础上,以750t/d生活垃圾焚烧炉与300MW等级亚临界机组耦合发电为例,针对高温烟气蒸汽汽轮机侧双耦合方案进行了典型负荷工况的计算,分析了耦合后对燃煤锅炉的影响,并进行了技术经济评估.研究结果表明:该耦合方案在技术上可行,且对燃煤机组的影响可控.与传统垃圾发电相比,此方案使垃圾发电的供电效率提高了10%以上,吨垃圾造价成本降低了约13%.生活垃圾与燃煤电站烟气蒸汽双耦合发电技术能显著提升效率并降低成本,具有低碳、环保、低成本等优点,符合国家产业政策导向.In order to promote the low-carbon transformation of coal-fired power units and the efficient treatment of domestic waste,this paper explores the technical route of coupling coal-fired units with domestic waste for power generation.Based on the research and analysis of various coupling schemes,this paper takes the coupling power generation of a 750 t/d domestic waste incinerator and a 300 MW subcritical unit as an example,and conducts calculations for typical loads specifically for the high-temperature flue gas side&steam turbine side dual coupling scheme.The impact on the coal-fired boiler after coupling are analyzed,and the technical and economic evaluations are performed.The research results indicate that this coupling scheme is technically feasible and has controllable impacts on the coal-fired unit.Compared with traditional waste-to-energy power generation,this scheme increases the power generation efficiency by more than 10%and reduces the cost per ton of waste by approximately 13%.The dual coupling technology of domestic waste and coal-fired power plant can significantly improve efficiency and reduce costs,with advantages such as low carbon,environmental protection and low cost,aligning with the guidance of national industrial policies.
