本文件规定了带或不带余热回收装置（WHRU）的工业燃气轮机（GT）排气系统的设计、施工材料、建模、控制、制造、检查、测试、安装、启动和运行的要求，并给出了建议。燃气轮机可以是陆上或海上的，用于石油和天然气、化工和加工工业、公用事业或其他能源密集型用户。 在本文件中，排气系统指燃气轮机排气收集器出口法兰和大气终端之间的涡轮排气流中的所有项目。 本文件不包括以下项目: -热回收蒸汽发生器设备（HRSG）； -辅助点火系统； -辅助燃烧系统； -废气收集器（也称为排气静压箱）； -火灾探测和灭火系统； -用于改变废气气体成分的排放控制设备； -燃烧管式WHRU，其中涡轮废气（TEG）通过管道。

This document specifies requirements and gives recommendations for the design, materials of construction, modelling, controlling, fabrication, inspection, testing, installation, start-up and operation of industrial gas turbine (GT) exhaust systems with or without waste heat recovery unit (WHRU). Gas turbines can be on-shore or off-shore for such sectors as oil and gas, chemical and process industries, utilities, or other intensive energy users. For this document, the exhaust system means all items in the turbine exhaust gas stream between the GT exhaust gas collector outlet flange and the termination/s to the atmosphere. The following items are not covered by this document: — heat recovery steam generator equipment (HRSG); — supplementary fired systems; — auxiliary fired systems; — exhaust gas collector (also known as exhaust plenum); — fire detection and extinguishing systems; — emissions controls equipment intended to modify the gaseous composition of the exhaust gas; — WHRUs that are of the firetube type, where the turbine exhaust gas (TEG) passes through the tubes.
