摘　　要：空冷汽轮机排汽管道由于其工况复杂、边界条件苛刻,一直是系统管道设计中的难点,除需要重点关注管道自身的结构和强度外,支吊架的设计也是影响机组安全的重要因素。文中介绍了一种空冷排汽管道支吊架系统的设计方法,提出管道的滑销系统的设计理念,采用此方法成功完成了某660 MW直接空冷汽轮机排汽管道的设计。Because the operating conditions of air cooled turbine discharge pipe are complicated,and the boundary conditions are rigorous,so it is always the difficulty in design.Besides the pipe’s construction and strength should be focusd on,the supports and hangers are important as well as possible.This paper presents a design method for air cooled turbine discharge piping supports and hangers,offers the concept of piping sliding key system.Using this method,a 660 MW ail cooled turbine discharge piping system and support and hanger system are successully designed.
