| 内容記述 | In recent years, global environmental problems, particularly global warming due to carbon dioxide (CO2), have become substantially evident. It is therefore necessary to investigate novel and efficient energy utilization methods, to significantly suppress CO2 emission, and thus preserve the environment. Ammonia (NH3) is a fuel that does not emit greenhouse gases. However, the burning velocity of NH3 is below 0.06 m/s, which is much lower than that of conventional hydrocarbon fuels (oil‐based fuels), making it difficult to achieve stable combustion of NH3. If NH3 is forcibly combusted, a large amount of NOX (toxic substance) will be generated. In this study, the calculations were performed using three chemical kinetic mechanisms (GRI Mech 3.0, Okafor Mech, Creck Mech), and the best mechanism was selected by comparing the experimental and calculation results. The GRI Mech 3.0 (Smith, et al) has a common reaction that has been used for the combustion calculation of many hydrocarbon fuels. The Okafor Mech (Okafor, et al, 2018) was improved NH3 reactivity based on GRI Mech 3.0 and Tian Mech. The Creck Mech (Stagni, et al, 2020) was a newly created mechanism and the mechanism for promoting the NH3/H2 reactions was added to the conventional scheme. By comparing the experimental and numerical data (i.e., flame structure and laminar burning velocity), it is found that that the Creck Mech was judged to be the most suitable chemical kinetic mechanism for ammonia burner with hydrogen flame stabilizer. | |||||||||||
