海上平台燃气轮机燃烧不均匀的分析处理

Analysis and Treatment of Uneven Combustion of Gas Turbines on Offshore Platforms

轻型工业燃气轮机作为一种功率密度大、反应速度快、可靠性高、体积小、自重轻的发动机,在各种工业领域都有广泛使用。燃气轮机通常有单燃料模式和双燃料模式,在油田开采等领域,多采用油田的伴生天然气作为燃料,以降低燃料成本。如果燃气轮机燃烧不充分、不均匀,常会出现T5温度与T5平均温度差值过大,此时机组有关停危险,严重影响了机组的安全运行和油田电力的稳定供应。文章针对典型轻型工业燃气轮机燃烧不均匀情况,通过总结实践情况与举一反三扩展分析的方式,进行原理分析、原因探讨及措施研究,介绍典型的实用处理技术,旨在为此类轻型燃气轮机燃烧不均匀情况的应对提供实践经验。

As a type of engine with high power density,fast reaction speed,high reliability,small size and light weight,light industrial gas turbines are widely used in various industrial fields.They are also commonly used for power generation operations in offshore oil field exploitation and other industrial fields.Gas turbines usually have single fuel mode and dual fuel mode.In fields such as oilfield development,the accompanying natural gas from the oilfield is often used as fuel to reduce fuel costs.If the combustion of the gas turbine is insufficient and uneven,there is often a large difference between the T5 temperature and the T5 average temperature.At this time,the unit is in danger of shutdown,which seriously affects the safe operation of the unit and the stable supply of oil field electricity.This article focuses on the uneven combustion of typical light industrial gas turbines.By summarizing practical situations and extending the analysis through analogy,the article conducts principle analysis,reason exploration,and measure research,and elaborates on typical practical treatment technologies.The aim is to provide some practical experience for dealing with such uneven combustion of light gas turbines.
