*** Serio 9204322 This Small Business Innovation Research Phase II will combine tomography, Hadamard signal encodement, and a patented Fourier Transform Infrared (FT-IR) emission/transmission (E/T) technique to perform spatially and temporally resolved soot and gas species measurements during combustion. One of the most important processes in combustion is the formation and destruction of soot. The concentration of soot controls the energy radiated by the flame and the effectiveness of soot destruction controls the combustion efficiency and the environmental acceptability of the combustion device. FT-IR E/T spectroscopy is currently the only means of simultaneous measurement of gas species compositions and temperatures and soot particle size, number density and temperature in a combustion flow. The effort to develop and validate the method of FT-IR E/T tomographic spectroscopy for sooting flames was accomplished during Phase I. The major advance achieved during Phase I was the inclusion and demonstration of Hadamard data processing as applied to FT-IR tomography. The primary objective of the Hadamard technique is to increase signal throughput, increase S/N and increase the speed of measurement. This was demonstrated for FT-IR tomography, but the Hadamard technique also adds a significant simplification in the tomography apparatus. Experiments on a co-annular diffusion flame clearly showed that the technique can identify hidden three-dimensional structure. The Phase II program will greatly improve time resolution and develop techniques for practically probing combustors that have limited optical access. The FT-IR E/T instrument can detect species which are important precursors to soot and is expected to lead to advances in understanding the chemistry and physics of soot formation. The Phase II program will lead to the development of a low-cost (under $50,000), portable, versatile, in-situ combustion diagnostic instrument which can be applied to combustion process control, pollution monito ring, or research and development. Applications include measurements in industrial gas turbines, industrial and residential furnaces, utility boilers, process heaters, jet engines, and diesel engines. *** p:\sbir\yhashimi\9204322b.doc

* Serio 9204322 该小型企业创新研究第二阶段将结合联合收割机层析成像、Hadamard信号编码和专利傅里叶变换红外（FT-IR）发射/传输（E/T）技术，以在燃烧过程中进行空间和时间分辨的烟尘和气体种类测量。燃烧中最重要的过程之一是烟灰的形成和破坏。烟灰的浓度控制火焰辐射的能量，烟灰破坏的有效性控制燃烧装置的燃烧效率和环境可接受性。FT-IR E/T光谱是目前唯一的手段，同时测量的气体种类的组成和温度和烟灰颗粒的大小，数密度和温度在燃烧流。在第一阶段完成了对炭黑火焰的FT-IR E/T层析光谱法的开发和验证工作。在第一阶段取得的主要进展是列入和阿达玛数据处理应用于FT-IR层析成像的示范。Hadamard技术的主要目的是增加信号吞吐量，增加S/N和增加测量速度。这被证明为FT-IR层析成像，但阿达玛技术也增加了一个显着的简化层析成像设备。对共环扩散火焰的实验表明，该技术可以识别隐藏的三维结构。第二阶段计划将大大提高时间分辨率，并开发用于实际探测光学通道有限的燃烧室的技术。FT-IR E/T仪器可以检测到烟尘的重要前体物质，并有望在了解烟尘形成的化学和物理方面取得进展。 第二阶段计划将导致开发一种低成本（低于50，000美元），便携式，多功能，原位燃烧诊断仪器，可应用于燃烧过程控制，污染监测或研究和开发。应用范围包括工业燃气轮机、工业和民用炉、电站锅炉、过程加热器、喷气发动机和柴油发动机的测量。 * p：\sbir\yhashimi\9204322b.doc
