The report gives results of an experimental study to determine if staged combustion can increase (enhance) the SO3 level in a combustion gas, relative to that observed in a similar single-stage process. Methane flames doped with H2S were used to examine the staging effects, employing a small quartz tube two-stage combustor. Examination of the staged combustion process suggests that the high CO levels produced in the first stage may pump a sufficient level of oxygen atoms into the second stage to increase SO3 formation. The results further suggest that the enhancement is small and may only be a transient early postflame phenomenon dependent on several combustion variables. A kinetic analysis of the data yields values of: (k sub 1) = 7.4 x 10 to the 14th power (cm to the 6th power) (mole to the minus 2) (sec to the minus 1) for the SO3 formation process, SO2 + O + M = SO3 + M; and (k sub 2) = 1.5 x 10 to the 11th power (cm cubed)(mole to the minus 1) (sec to the minus 1) for the depletion process, SO3 + O = SO2 + O2 (T = 1685 K). The kinetic analysis also shows that enhancement of SO3 formation can occur in staged combustion.
