Interactions between certain fuel sulfur compounds and nitric oxide (NO) in turbulent gaseous and distillate oill diffusion flames were experimentally investigated utilizing a 75,000 Btu/hr laboratory combustor. Aerodynamics, air preheat conditions, and overall excess air conditions were varied to determine their role on any such interaction. Results indicated that addition of sulfur dioxide (SO2) to natural gas flames could enhance or inhibit NO emissions. Local flame stoichiometry and temperature, which were influenced by fuel injector type, determined which effect was observed and the extent to which it occurred.

The objective of the present program is to study the structure and response of steady and unsteady laminar premixed and nonpremixed flames in reduced and elevated pressure environments through (a) non-intrusive experimentation, (b) computational simulation using detailed flame and kinetic codes, and (c) asymptotic analysis with reduced kinetic mechanisms. During the reporting period progress has been made in the following projects: (1) a theoretical and experimental study of unsteady diffusion flames; (2) a computational and experimental study of hydrogen/air diffusion flames at sub- and super-atmospheric pressures; (3) an asymptotic analysis of the structure of premixed flames with volumetric heat loss; (4) asymptotic analyses of ignition in the supersonic hydrogen/air mixing layer with reduced mechanisms; (5) a new numerical algorithm for generating the ignition-extinction S-curves. A total of three reprints are appended.
