有或无余热回收的燃气轮机排气系统

[中文适用范围]： 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、结构材料、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。 ）。 燃气轮机可以安装在岸上或离岸，用于石油和天然气、化学和加工业、公用事业或其他密集型能源用户等领域。 对于本文件，排气系统是指 GT 废气收集器出口法兰和大气终端之间的涡轮机废气流中的所有项目。 本文件不包括以下项目： ——热回收蒸汽发生器设备（HRSG）； ——补充发射系统； ——辅助发射系统； ——废气收集器（也称为排气室）； ——火灾探测和灭火系统； ——旨在改变废气气体成分的排放控制设备； ——WHRU 属于火管类型，涡轮机废气 (TEG) 通过管子。 [外文原描述]： 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.
