Show devolatilization process. The other possibility is that the packaged waste produced a tacky ash causing a particulate buildup that was not readily apparent. Downstream of the kiln, a secondary combustion chamber was used to heat the kiln effluent from 1600 to 1800 degrees F. Emissions data for carbon monoxide, NOx ' and SOx can be found in Table IV. All gas measurements were made on the gas exiting the stack downstream of the secondary combustion chamber and flue gas quench system. The amount of carbon monoxide emitted from the stack on a dry gas volumetric basis ranged from 0.4 ppm to 3.0 ppm. The NOx emissions ranged from 87 to 148 ppm, and the SOx emissions ranged from 37.9 to 328.2 ppm (average dry gas volume basis). The HCI emissions ranged from 2.4 to 23.3 ppm, and the chlorine emissions ranged from 1.3 to 55.7 ppm.

On a dry basis, the ash collected in the ash trough was between 99.66 and 99.9 percent non-combustible. The ash fusion fluid temperatures ranged from 2115 to 2140F. The total organic carbon content of the ash ranged from 73.9 to 117 parts per million. Ash as well as scrubbing water samples were sent to ENSECO/Rocky Mountain Analytical for CCWE (Chemical contaminant Waste Extract) analysis. All CCWE compounds were non-detected. Particulate emissions from the stack were analyzed for particle size distribution and metal content. The particle size distribution data is presented in Table VI. In Table V the particle size data is summarized. On the average, 84 percent of 7 |
