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

cts - 0521136 - i。这笔拨款是为了获得两台仪器，这将有可能获得非常需要的火焰和燃烧器特性的图像。第一种仪器是一套高速（每秒几百帧）高容量数字（ccd充电对显）摄像机，用于在稳定和不稳定条件下对火焰的时间演变进行数字成像。第二个仪器是一个激光器，使PLIF（平面激光诱导荧光）测量。这些仪器将用于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)提高工业炉的效率和降低排放；所要求的设备将支持研究，为如何设计满足“晴空倡议”和“全球气候变化倡议”的炉和燃烧器提供真实规模的工作炉和锅炉。(2)在一定条件下，可以在锅炉燃烧室中生产碳纳米管，从而为大规模生产具有先进质量的碳纳米管提供了可能。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。该设备将支持工作炉中纳米管发展的基本机制研究，并为工业规模纳米级组件的生产方法的发展提供基础。

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.
