A screening study was performed on a laboratory scale downfired combustor to determine the effect of various variables on the effectiveness of the reburning process as a technique for NO{sub X} abatement. The objective was to define optimum conditions under which reburning can be used and to be able to compare the reburning performance of our combustor to those reported by others. For this purpose, a statistically designed parametric investigation was conducted to determine how a set of controlled variables (primary and secondary stoichiometric ratios, location and length of the reburn zone and primary fuel load) would affect the reduction in NO emissions due to reburning. Also, the effects of other variables (NO in the primary zone, temperatures in the primary, reburn and burnout zones and the residence time in the reburn zone) were also investigated.
