Fast infrared camera for fundamental studies of metal flames

目前的NSERC RTI赠款申请是用于购买快速红外（IR）摄像机，用于金属燃料燃烧的高级诊断。该摄像机将提供金属燃料火焰的时间和空间分辨的热图像。该相机还将兼作红外光谱仪的高速探测器，允许表征在红外区域发射和吸收的气态物质，即水，二氧化碳和一氧化氮。更具体地说，相机将用于获得湍流铁燃料燃烧器的温度场，我们正在通过NSERC战略伙伴关系项目赠款的支持进行开发。从建议的红外摄像机获得的数据将用于改善燃烧器的性能。此外，该相机将用于使用产生一维平面金属火焰的加热逆流燃烧器进行金属火焰的基础研究。这些研究将包括一氧化氮排放的特性、火焰的热结构以及火焰厚度。这些数据对于我们进一步了解金属燃料的基本燃烧特性至关重要。

The present NSERC RTI grant application is for the purchase of a fast infrared (IR) camera for advanced diagnostics in metal fuel combustion. The camera would provide temporally and spatially resolved thermal images of metal fuel flames. The camera would also double as the high-speed detector of an infrared spectrometer, allowing the characterization of gaseous species that emit and absorb in the infrared region, namely water, carbon dioxide, and nitric oxide. More specifically, the camera would be used to obtain the temperature field of a turbulent iron fuel burner that we are developing through the support of a NSERC Strategic Partnerships Grant for Projects. Data obtained from the proposed IR camera will be used to improve the performance of the burner. Furthermore, the camera will be used to perform fundamental studies of metal flames using the heated counterflow burner that produces one-dimensional, flat metal flames. The studies will include the characterization of nitric oxide emissions, the thermal structure of the flame, as well as the flame thickness. These data are essential to further our understanding of the fundamental combustion properties of metal fuels.
