Show EXPERIMENTAL FACILITY As previously discussed, a practical incinerator involves complex flow and chemical reaction regimes which are difficult to accurately model. Before precise models of actual incinerator conditions may be developed, more fundamental knowledge regarding flame mode decomposition needs to be obtained. One method historically used [5] to acquire fundamental flame mode data involves the study of one dimensional, laminar or so-called, "flat" flames. Throughout such flames, both concentration and temperature gradients occur only in a single spatial direction. A schematic representation of a typical flat flame and resulting concentration profiles is presented in Figure 1. Such flames were generated in this study. A description of the basic combustion laboratory and facility used to generate the flame mode data of this paper have been presented in detail, elsewhere [6,7]. The principal installation of the laboratory is a Holthius Flat Flame Burner [8]. The burner has a 6.0 cm diameter, sintered, stainless steel plug with heating/cooling coils embedded in it. The flames were shielded from possible entrainment effects by passing a concentric nitrogen (N^) shroud gas around the flame holder through a bronze porous plug of 6.6 cm diameter. The burner assembly is surrounded by a 15.2 cm Pyrex cross and supported by a 2.9 cm diameter Teflon rod. Each opening of the cross is fitted with blind flanges especially fabricated to house various transducers and/or probes. The exhaust gases are evacuated from the Pyrex cross and subsequently drawn through a condenser, a cold trap and a flow control valve before entering an oxygen rated vacuum system (Edwards EDM20).
