摘要

作为Uniper到2035年在欧洲发电中实现碳中和战略的一部分，位于瑞典Malmö的Kraftwerk Union/Siemens V93.0燃气轮机(GT)于2021年7月以加氢处理植物油(HVO)作为低碳汽油替代品运行。在HVO运行之前，进行了可行性研究，包括燃料比较、火焰温度建模和危险识别研究。在为期两天的演示中，在启动、满载、部分负载和关闭时，使用汽油或HVO监测了GT的性能。测量了NOx, CO, SO2和粉尘的认可排放量，以便在燃料之间进行比较。在点燃HVO时，没有遇到不良的GT操作，并使用直接火焰成像观察HVO在启动时的成功点火过程。名义上，在HVO操作期间，NOx排放量与汽油相似。因此，用于控制NOx的注水速度在不同燃料之间是不变的，这证实了火焰温度模型的预测。HVO运行过程中粉尘、CO和SO2排放减少。与化石天然气相比，HVO还能显著减少生命周期内的二氧化碳排放，在本次试验中可避免约163吨二氧化碳排放。该试验为今后现场燃料转换提供了依据。需要进行进一步的测试和监测，以获得有关HVO运行对燃料储存、燃料输送和热气路组件的长期影响的证据。据作者所知，这次试验是世界上第一次成功演示HVO在工业燃气轮机中的应用。

Performance, Emissions, and Decarbonization of an Industrial Gas Turbine Operated with Hydrotreated Vegetable Oil

Abstract As part of Uniper's strategy for carbon neutrality in its European power generation by 2035, a Kraftwerk Union/Siemens V93.0 gas turbine (GT) in Malmö, Sweden was operated with hydrotreated vegetable oil (HVO) as a low-carbon replacement for gas oil in July 2021. Prior to HVO operation, a feasibility study was conducted including fuel comparison, flame temperature modelling, and a hazard identification study. During the two-day demonstration, GT performance was monitored using either gas oil or HVO at start-up, full load, part load, and shut-down. Accredited emissions of NOx, CO, SO2, and dust were measured to allow comparison between fuels. When firing HVO, no adverse GT operations were encountered, and direct flame imaging was used to observe the successful HVO ignition process at start-up. NOx emissions were nominally similar to gas oil during HVO operation. Therefore, the water injection rate for NOx control was unchanged between fuels, confirming the predictions of the flame temperature modelling. Dust, CO, and SO2 emissions reduced during HVO operation. HVO also enables significant lifecycle CO2 emissions reductions compared with fossil gas oil with ~163 tCO2 emissions avoided in this trial. This trial provides evidence for future site fuel conversion. Further testing and monitoring is required to develop evidence regarding the long-term impact of HVO operation on fuel storage, fuel delivery, and hot gas path components. To the authors' knowledge, this trial is the first successful demonstration of HVO use in an industrial gas turbine in the world.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
