摘要：

垃圾焚烧发电已成为我国垃圾处理的主流方式，在双碳目标的背景之下，提升垃圾焚烧发电厂的能效水平是当前垃圾焚烧行业运行的重点。文章（文摘宜用第三人称。）讨论了垃圾焚烧发电厂不同余热供暖技术路线及优缺点，并以华东北部某垃圾焚烧发电厂为研究对象，分析了余热供暖技术在该厂的运行效果。研究结果表明，采用余热供暖技术，全厂能效在冬季供暖期突破50%，最高可达71.33%。垃圾焚烧发电厂余热利用供暖可提高焚烧厂的社会环境效益、经济效益、碳减排效益，单个供暖季可节约2.5万吨标准煤，碳减排量约6.6万吨。促进垃圾焚烧处置设备及系统的技术优化，提高行业的高质量发展水平。

Abstract:

Waste-to-energy(WTE) has become the mainstream way of waste treatment method in China. Improve the energy efficiency of waste incineration power plants is currently the focus of the operation of the waste incineration industry in the context of Carbon Peaking and Carbon Neutrality Goals. This paper analyzes the waste heat utilization effect of a waste incineration power plant in Northeast China, and different waste heat utilization technology routes are discussed. The research results indicate that the adoption of waste heat heating technology enables the overall plant efficiency to exceed 50% during the winter heating period, with a maximum efficiency of up to 71.33%. The utilization of waste heat for heating in waste incineration power plants can improve the social environmental benefits, economic benefits and carbon emission reduction benefits of the incineration plant, promote the technical optimization of waste incineration disposal equipment and systems, and improve the quality of the industry.
