NH3/H2/DME三元燃料层流预混火焰特性的化学动力学研究
Chemical kinetics study of laminar premixed flame characteristics for NH3/H2/DME ternary blends
氨作为一种新型能源载体和清洁零碳燃料，其应用对动力装置实现碳中和具有重要战略意义。但氨燃烧存在火焰稳定性低、反应活性低、自燃着火温度高及NOx排放高等缺点。针对以上问题，基于化学动力学对H2/DME助燃氨燃烧的三元燃料层流预混火焰基础燃烧特性开展相关研究。构建并验证了NH3/H2/DME三元燃料化学反应机理，探究了常温常压下H2/DME掺混对氨燃料复合燃烧层流火焰特性的影响机制。研究结果表明H2侧重提高复合燃烧层流火焰锋面OH浓度，而DME侧重提…查看全部>>
As a new type of energy carrier and clean zero-carbon fuel, the application of ammonia is strategic significance for achieving carbon neutrality in power plants. However, ammonia combustion has the disadvantages of low flame stability, low reactivity, high auto-ignition temperature and high NOx emission.For the above problems, a relevant study is carried out to characterize the combustion of ternary fuel laminar premixed flame basis for H2/DME fueled ammonia…查看全部>>
