Show of the kiln and, subsequently, the relative role of the afterburner to ensure adequate destruction. Based on the results of the first set of response surface experiments, a second and third series of two dimensional tests were performed in an attempt to separate the individual effects of stoichiometric ratio, post flame oxygen flow, and post flame oxygen partial pressure. The design of the response surface experiments was limited. It is evident from Figure 2 that, for the response surface experiments, the three oxygen parameters (stOichiometric ratio, post flame oxygen flow, and post flame oxygen partial pressure) are highly correlated with each other and vary in the same manner. In fact, due to the constant auxiliary fuel load used for these experiments, specification of either stoichiometric ratio or post flame oxygen flow defines the other. To separate these effects, two sets of additional experiments were designed, varying the auxiliary fuel load. These trial matrices are presented in Tables II and III. The trial matrix in Table II, was designed to vary the post flame oxygen flow and partial pressure independently while holding stoichiometric ratio constant. The trial matrix in Table III, varies stoichiometric ratio and post flame oxygen partial pressure while holding post flame oxygen flow constant. The individual data sets were collected in the same manner as described previously for the response surface experiments, and other kiln operating parameters were held constant as described above. It was hoped that the additional experiments might indicate whether post flame oxygen flow or post flame oxygen partial pressure had the greater influence on transient puffs. While the post flame oxygen flow (total molar oxygen flow to which the waste charge is exposed) may be varied without oxygen enrichment, variation of the post flame oxygen partial pressure is limited without oxygen enrichment. 8 |
