Chemiluminescence imaging of flames with partial premixing
FY 2006-07
Summary
I am requesting funding to purchase the apparatus for chemiluminescence imaging in flames. Chemiluminescence is the light emission from an atom or molecule that is electronically exited by a chemical raction. In falmes, the intensity of the reaction rate is proportional to the magnitude of OH* and CH* chemiluminescence and its measurements map out the spatial and temporal distribution and variations of the combustion process heat release. The flame chemiluminescence will be acquired with high speed filming of the combustion zone with an intensified imager camera. The proposed equipment will be used in support of research on low temperature oxidation in which flames are partially premixed and contain large amounts of recirculated combustion products. This research program is focused on a laboratory scale realization of "flameless oxidation" burners that have been investigated by the applicant before at full-scale. These are extremely low polluting, efficient combustion devices relaying on separate injection of fuel and air directly into the furnace, entraining combustion products and lowering the flame temperature and NOx emissions. The small-scale realization is an inverse non-premixed flame burner with co-flowing streams that deliver air, fuel, inert gas (e.g. N2), and heated combustion products. Initial characterization of such a burner in terms of flame visualization, stability limits, and temperatures was completed and results were published. To make further qualitative progress, the level of premixing and the effects of product gasses entrainment on the reaction rate need to be quantified, and chemiluminescence is an ideal technique with which to do it. The requested imaging system will be also suitable for other low temperature combustion studies, including Homogenous Charge Compression Ignition (HCCI) in engines, and combustion with H2 and CO supplementation. The chemiluminescence technique is an exciting flame diagnostics technique that present ample opportunities for training graduate students in the area of data acquisition, image processing and combustion visualization.
