催化裂化装置烟气轮机入口管道设计浅谈

Design of Inlet Piping of FCCU Flue Gas Expander

烟气轮机是催化裂化装置能量回收系统的核心设备,烟气管道设计水平将直接影响烟气轮机能否正常运行。文章从烟气轮机对烟气管道的要求出发,介绍烟气轮机人口管道设计要点,包括典型流程、布置方式、膨胀节选用和支吊架设置等。提出了烟气管道的设计原则,分析了设计中应注意的问题。

Flue gas expander is the core equipment of FCCU energy recovery system, flue gas piping design level will directly affect the flue gas can run normally. The article embarks from the flue gas demand for flue gas piping, introduces population flue gas piping design key points, including the typical process, arrangement, steam-water expansion from use and Settings, and so on. Put forward the design principle of flue gas piping, analyzes the problems that should be paid attention to in design.
