为推进零碳燃料氨/氢掺混燃烧在燃气轮机中的应用,针对氨/氢燃料的掺混设计和燃烧性能开展研究.以氨/氢掺混燃烧设计为目标,以天然气的燃烧性能为参照,采用可靠的燃烧反应机理,在较宽工况范围和不同掺氢比下开展了氨/氢掺混燃烧特性及其可行性的数值研究,并确定了氨/氢混燃用于燃气轮机仿真实验研究的合理配比;同时系统分析了氨/氢掺混燃烧过程中NO的生成路径以及影响氨和氨/氢掺混燃烧温度变化的关键反应.结果表明:在点火延迟时间、绝热火焰温度、火焰传播速度等典型基础燃烧特性的判据下,氨/氢燃料在掺氢比为50％～55％范围内的燃烧性能与天然气相当;另外,氢气的掺混显著拓宽了氨气的稳定燃烧范围,为进行实际的燃气轮机工程燃烧仿真研究提供可行的掺混方案.
Ammonia/Hydrogen Fuel Blending Design and Its Combustion Characteristics for Gas Turbines
In order to promote the application of zero-carbon ammonia/hydrogen blending combustion in gas turbines,the design and combustion performance of ammonia/hydrogen blending were studied.Tak-ing the ammonia/hydrogen blending combustion design as the goal,taking the combustion performance of natural gas as the reference,and using the reliable combustion reaction mechanism,the numerical study of the combustion characteristics and feasibility of ammonia/hydrogen blending under a wide range of working conditions and different hydrogen blending ratios was carried out,and the reasonable ratio of am-monia/hydrogen blending combustion for gas turbine simulation experiments was determined.Meanwhile,the formation path of NO during ammonia/hydrogen blending combustion and the key reactions affecting the temperature change of ammonia and ammonia/hydrogen blending combustion were systematically ana-lyzed.The results show that the combustion performance of ammonia/hydrogen fuel in the range of 50％-55％hydrogen blending ratio is comparable to that of natural gas under the criterion of typical basic com-bustion characteristics such as ignition delay time,adiabatic flame temperature and flame propagation ve-locity.In addition,the blending of hydrogen significantly broadens the stable combustion range of ammo-nia,which provides a feasible blending scheme for actual combustion simulation research in gas turbine engineering.
