MRI: Acquisition of Instrumentation to Characterize the Mechanisms of Combustion Instability and Resulting Flame Structure

CTS-0521136I。这笔赠款是为了购买两台仪器，这两台仪器将有可能获得急需的火焰和燃烧器特征图像。第一台仪器是一套高速(每秒数百帧)高容量数字(电荷耦合显示)相机，用于对稳定和不稳定条件下火焰的时间演变进行数字成像。第二种仪器是激光，可以进行PLIF(平面激光诱导荧光)测量。这些仪器将被用来研究火焰不稳定的机理。该设备将支持两个具有广泛技术和社会影响的领域的研究：(1)提高工业熔炉的效率和降低排放；所要求的设备将支持研究，这些研究将在真实世界规模的工作熔炉和锅炉中提供洞察力，了解如何设计满足“晴朗天空倡议”和“全球气候变化倡议”的熔炉和燃烧器。(2)在某些条件下，可以在锅炉燃烧室中生产碳纳米管，从而有可能以最先进的质量大规模生产纳米管。研究纳米颗粒形成和加工过程中的火焰结构是理解和控制纳米管生产过程的关键。该设备将支持在工作炉中开发纳米管的基本机理的研究，并为工业规模的纳米元件生产方法的开发提供基础。

CTS-0521136I. Rabovitser, Gas Technology InstituteThis grant is to acquire two instruments that will make it possible to obtain much needed imagery of flame and burner characteristics. The first instrument is a set of high-speed, (several hundred frames per second) high capacity digital (CCD-charged couple display) cameras to digitally image the time evolution of flames during both stable and unstable conditions. The second instrument is a laser to enable PLIF (planar laser-induced fluorescence) measurements. These instruments will be used to study the mechanisms of flame instability. The equipment will support research in two areas of broad technical and societal impact:(1) Increased efficiency and lower emissions for industrial furnaces; the requested equipment will support research that will provide insight, in real-world-scale working furnaces and boilers, on how to design furnaces and burners that address the "Clear Skies Initiative" and "Global Climate Change Initiatives." (2) Under certain conditions, carbon nanotubes can be produced in the boiler combustion chamber, leading to the possibility of large-scale nanotube production with state-of-the-art quality. A study of the flame structure during nanoparticle formation and processing is a key to understanding and controlling the nanotube production process. The equipment will support research on the fundamental mechanisms of nanotube development in working furnaces and provide a basis for the development of production methods for nano-scale components on an industrial scale.
