摘　　要：近几年随着火电机组供热和深度调峰需求的提出,具备条件的现役火电机组,因厂制宜地陆续开始实施供热改造,以提高能源综合利用效率,完成节能减排的目标。目前国内300 MW及以上容量机组供热改造多采用打孔抽汽供热改造、低压缸切缸改造技术,本文对上述两种抽汽改造方案的异同,以及抽汽管道的布置方案进行分析讨论,以期能为后续改造项目提供参考。In recent years, with the demand of heating and deep-peak regulation of thermal power units, qualified thermal power units have begun to carry out heating retrofit according to plant conditions, in order to improve the comprehensive utilization efficiency of energy and achieve the goal of energy conservation and emission reduction. At present, the heating retrofit of 300 MW and above capacity units in China mostly adopts the technology of drilling steam extraction heating retrofit and low-pressure cylinder cutting cylinder retrofit. This paper analyzes and discusses the similarities and differences between the above two kinds retrofit technologies and the layout of steam extraction pipeline, in order to provide reference for the subsequent projects.
