摘要
针对输气管道站场中传统单环形燃烧(SAC)和干式低排放燃烧(DLE)两种类型燃气轮机的大气污染物组分,采用现场测试方法,对两种燃气轮机在不同工况下排放烟气中的氮氧化物(NO_(x))、一氧化碳(CO)、燃烬碳氢化合物(UHC)等大气污染物组分进行实际测试与分析,并进一步开展DLE型燃气轮机转速对其机组效率和烟气组分的影响研究。结果表明,DLE燃气轮机在NO_(x)排放控制方面明显优于SAC燃气轮机,并保持较高的热效率,但在UHC和CO组分排放方面仍有提升空间;机组效率随转速增加呈现先增大后减小的趋势,在5400 r/min时达到最优。通过对比分析,该研究揭示了温度对烟气组分排放的影响机制,为燃气轮机的环保性能优化提供了参考,对推动燃气轮机行业的绿色发展具有重要意义。
For the components of air pollutants in two types of gas turbines,namely traditional single ring combustion(SAC)and dry low-emission combustion(DLE),in gas transmission pipeline stations,on-site testing methods are adopted.Actual tests and analysis are conducted on the components of atmospheric pollutants such as nitrogen oxides(NO_(x)),carbon monoxide(CO),and burned hydrocarbons(UHC)in the flue gas emitted by two types of gas turbines under different working conditions,and further research is carried out on the influence of the rotational speed of the DLE type gas turbine on its unit efficiency and flue gas components.The results show that the DLE gas turbine is significantly superior to the SAC gas turbine in terms of NO_(x) emission control and maintains a relatively high thermal efficiency,but there is still room for improvement in UHC and CO component emissions.The efficiency of the unit shows a trend of increasing first and then decreasing with the increase of rotational speed,reaching the optimum at 5400 r/min.Through comparative analysis,this study reveals the influence mechanism of temperature on the emission of flue gas components,providing a reference for the optimization of the environmental protection performance of gas turbines and is of great significance for promoting the green development of the gas turbine industry.
