燃气-蒸汽联合循环部分负荷热不平衡的优化

基于燃气-蒸汽联合循环余热锅炉内两个不同主体的热量模型计算与分析,研究了某联合循环发电厂在燃气轮机负荷工况下蒸汽侧热不平衡问题的来源与热力循环特点,并提出了适应此类工况条件下的汽轮机优化运行方式,以提高联合循环发电机组的运行经济性.;Based on the thermal model calculations of the two sections of HRSG in a certain gas-steam combined cycle, the cause of the thermal unbalance and the features of the heat cycle of a part-load running unit of a combined cycle power plant are studied, and a proper running model of gas optimization for this kind of operation condition is suggested so as to improve the economic efficiency of combined cycle generating units
