Keyword:  CCPP有机工质耦合模型技术集成正能量系数;
Abstract: 基于梯级利用方法,提出了燃气-蒸汽-有机工质联合循环发电工艺,建立了理论耦合计算模型,并以北京太阳宫燃气热电有限公司350MW机组的设计和运行工况参数为基础,对研发的新工艺与太阳宫原工艺进行热经济性对比分析.计算表明:依据正能量系数,优选R141b工质的设计工况下,燃气-蒸汽-有机工质联合循环新工艺发电功率达800.1MW,发电效率达59.1%;运行工况下,新工艺发电功率达566.65MW,发电效率达54.51%,设计工况下分别比太阳宫原工艺提高了20.1MW和1.48%;运行工况下分别提高了15.45MW和1.45%.
