为了优化燃气涡轮机燃烧室在排放、循环效率和部件寿命方面的运行，必须更加重视诊断技术和更灵活的控制方案。化学发光是一个明显的选择，并且是这种诊断工具的相对容易和低成本的选择。应用实例包括光谱分析和光强度缩放，研究火焰动态效应的时间分析和解决热释放区域空间分布的成像技术，以及相位匹配成像和使用高速成像跟踪点火核等方法的组合。进一步的基础工作应触发的性质为激发的物种和它们的形成途径，以及它们的连接到热释放和NOx的形成过程。
To optimise the operation of gas turbine combustors with respect to emission, cycle efficiency and components lifetime, increased attention has to be attributed to diagnostic techniques and more flexible control schemes. Chemiluminescence is an obvious choice and a relatively easy and low cost option for such a diagnostic tool. Application examples include spectral analysis and light intensity scaling, temporal analysis studying flame dynamic effects and imaging techniques resolving spatial distribution of heat release zones, as well as combinations of the methods like phase matched imaging and tracking of ignition kernels using high speed imaging. Further fundamental work should be triggered on the nature for the excited species and their formation pathways as well as their connection to heat release and the NOx formation processes.
