| 英文摘要 | The modification of our energetic mix is one of the crucial challenges to mitigate climate change. Various solutions are studied, and we will probably use most of them in the future. One of these solutions is metal combustion. Indeed, metals have important energy properties, and the combustion of metal powder does not produce greenhouse gases except NOx, and also generates oxides which can be extracted then recycled to transform them back into fresh combustibles. Among others, Aluminum (Al) is very present on earth to gratify the potential global needs. As a matter of fact, Al possesses an important energetic density as compared to other metals like iron. Due to the difficulty of stabilizing dust flames only fed by Al in air, some applications should choose hybrid flames. The main objective of this study is to better characterize flames burning aluminum blended with CH4. As an original contribution, a non-invasive methodology, i.e. two-color pyrometry, has been set up to do so. This article unveils the structure of such a flame fed by a high level of particle density. Through the observation of flame radiation and the evaluation of flame thickness, it was concluded that the quantity of injected methane could significantly change the regime of the central premixed flame that directly impacts the contribution of the diffusion flame to the reaction. |
