(DOE Energy Conversion and Utilization Technology Program: NBS Measurement Technology Project): Annual report, March 1981-March 1982
The most important consequence of the trend towards utilization of fuels with higher C/H ratio and lower volatility is expected to be the increased rate of soot formation in combustion processes. This could have detrimental effects on both industrial combustion systems (boilers, furnaces, and stationary GTE's) as well as transportation systems (IC engines and aircraft GTE's) through increased radiative heat transfer, increased erosion of downstream components, and increased particulate emissions. Proper understanding of sooting processes will aid in assessing the impact of alternative fuels on hardware durability, combustion and heat transfer efficiency, and the environment. Soot formation entails a number of complex processes that occur within and about the combustion zone. These include hydrocarbon cracking, nucleation, growth, agglomeration and burnout. The importance of free radical processes, the involvement of aromatic and acetylenic intermediates, and the effect of inorganic components on the soot formation processes will be investigated. The effect of physical properties (such as boiling point and viscosity) on the droplet formation, evaporation, combustion and subsequent soot formation processes will also be examined. The effect of flow field parameters on the chemical, as well as physical processes will be studied. Initial studies toward investigation of chemical effects on soot formation are being carried out in laboratory-scale diffusion flames of various configurations. 11 refs., 2 figs.
