摘要
结合LNG站的冷能综合利用研究课题,分析燃气-蒸汽联合循环电站与LNG站气化冷能的耦合利用,并对冷源选择、设备选型、进风温度优化进行技术经济分析.在环境温度较高时,通过合理利用冷能,降低燃机进风温度及凝汽器背压,可大幅提高燃气-蒸汽联合循环电站出力.
Abstract
Based on the research topic of comprehensive utilization of cold energy in LNG stations,this paper analyzes the coupling utilization of gasification cold energy between gas steam combined cycle power plants and LNG stations,and conducts technical and economic analysis on cold source selection,equipment selec-tion,and inlet air temperature optimization.When the ambient temperature is high,by utilizing cold energy rea-sonably,reducing the inlet temperature of the gas turbine and the back pressure of the condenser,the output of the gas steam combined cycle power plant can be significantly improved.
