摘要(Abstract)：
为使正在建设中的一批大型联合循环电厂单位投资省、热效率高、投产后具有较好的效益,对大型天然气联合循环发电技术进行全面而系统的研究和优化至关重要。文章对影响大型天然气联合循环电厂效率的各种因素进行了研究,对联合循环系统的优化、燃气轮机选型、蒸汽系统的优化、参数选择、余热锅炉和汽轮机选型、机组轴系配置等方面进行了深入的分析研究,并提出了明确的优化途径和结论。
In the East China a batch of large-scale combined cycle power plants is building in order to coordinate the West-to-East Gas Transmission project,oil gas from the East Sea and input of liquid natural gas.It's critically important to research and optimize power generation technology of large-scale natural gas-fired combined cycle,since it means less investment per kilowatt,high heat efficiency and more beneˉfit.This paper makes research on the various factors which affect the efficiency of large-scale combined cyˉcle power plant.And this paper makes deep analysis to optimization of combined cycle system,model selection of gas turbine,optimization of steam system,parameter selection,model selection of HRSG and steam turbine,shafting configurations of unit.The definite ways of optimization and conclusion are put forward in the paper.
