摘　　要：依托F级改进型联合循环工程对重型燃机运行工况进行分析,根据燃机对压缩空气的特殊要求,详细研究空气压缩机及其储气罐的选型方法,计算结果表明采用4台25 Nm^3/min容量的空压机和4套30 m^3储气罐在满足机组安全运行的前提下,使静态投资成本最低。此外,通过对压缩空气系统的设计优化,改进了厂用服务压缩空气系统,使其储气罐在紧急事故工况下能为仪用压缩空气系统服务,更能保障机组的安全运行。通过本工程计算实例,为将来同类工程的压缩空气系统优化计算提供借鉴作用。By the analysis on F advanced class combined cycle power plant operation conditions,sizing calculation method of air compressor and air receiver is investigated as per gas turbine special requirements.The calculated results show that 4 air compressors with capacity of 25 Nm^3/min and 4 receivers with capacity of 30 m can make units running in safe condition and meet the minimum static investment requirement.The optimization design of the compressed air system has improved plant service air system to enable the air receiver to be served for the instrument air system during emergency condition.With the engineering practice in this project,it will provide reference to future similar engineering calculation for compressed air system.
