SBIR Phase I: Control and Optimization of Combustion Based on Multispectral Emission Tomography

这个小型企业创新研究(SBIR)第一阶段项目研究了一种直接测量关键燃烧流场信息的新方法，这是主动控制所需的，以提高燃烧效率和减少有害排放。这一建议的关键创新是使用光谱传感器技术和层析重建技术来实验确定这种函数关系。通过在流过的多个视线上进行大量测量，实现了流场的表征。一旦确定了传感器与流量的功能关系，过程工程师就可以使用少量战略性放置的传感器来实施主动控制系统。拟议的第一阶段研究为一系列多燃烧器燃烧器的主动控制系统奠定了科学基础，包括涡轮发动机、锅炉和过程燃烧器。这些应用占全球化石能源使用量的50%以上；因此，效率的提高可以产生重大的经济和社会影响。

This Small Business Innovation Research (SBIR) Phase I project investigates a novel approach for directly measuring critical combustion flow-field information required for active control to increase combustion efficiency and reduce harmful emissions. The critical innovation in this proposal is the experimental determination of this functional relationship using spectral sensor technology and tomographic reconstruction techniques. Flow field characterization is achieved using a large number of measurements over multiple lines of sight through the flow. Once the sensor-to-flow functional relationship is determined, the process engineer can implement an active control system using a small number of strategically-placed sensors. The proposed Phase I research lays the scientific ground work for active control systems for a range of multi-burner combustors, including turbine engines, boilers, and process burners. These applications represent more than 50% of the global fossil energy usage; thus improvements in efficiency can have a major economic and societal impact.
