J' rr ~j Emission Test Report EMCWA-2-08 Section 3 Revision: 0 Date: September 30. 1999 Page 5 of 33 I I last duct bend after the secondary combustion chamber, and the Method 23 outlet train was located nearest to the scrubber outlet. More turbulent flow expected at these locations may explain the higher flow results obtained with the Method 23 trains. Because flow was different at each traverse point at any given time across each sampling cross-section and flow varied at each of those points during the course of a run, consistent flow results could not be obtained among the trains used at the inlet or the outlet during any run. Results of testing for total particulate matter are presented in Table 3-8. As indicated from the data, inlet and outlet concentrations for each run were very similar, regardless of condition thereby indicating that the scrubber had little, or no effect on particulate matter removal. Data from particulate matter testing are found in Appendix H. : j ~ ~ ] 3.4.2 Hydrogen Chloride Analysis Results ] '"i,' i '\ Hydrogen chloride emission results are presented in Table 3-9 in units of both grams per minute and pounds per hour. While, emissions appear to be lower at the scrubber outlet than at the inlet for Condition 1, the HCI concentrations are too low at the inlet relative to the outlet locations for removal efficiencies to be meaningful. HCI data are included in Appendix E. '1 U 3.4.3 Metals Analysis Results r-l L Metals results, blank corrected results and emission rates are shown in Tables 3-10 through 3-12. Cadmium and lead emissions tend to increase with secondary combustion chamber temperature increase; mercury emissions were less affected by temperature than the other two metals. The increase in metals emissions with increasing temperatures is not uncommon, however, the amount of cadmium and lead charged during each run may also have contributed. The metals narrative report with analysts' results are included in Appendix F. u 3.4.4 Dioxin and Furan Results ] [01 Dioxin and furan results are provided in Tables 3-13 through 3-24, grouped by condition. Tables 3-13 through 3-16 provide results for Condition 1 testing, Tables 3-17 through 3-20 provide results for Condition 2 testing, and Tables 3-21 through 3-24 provide results for Condition 3 testing. Results for each condition are presented first by total amount found within a given homologue, next by the 2,3,7,S-substituted compounds, then by the corresponding equivalent toxicity of 2,3,7 ,S-tetrachloro-dibenzo-dioxin for inlet and outlet. The dioxin and furan narrative report is included in Appendix G. It should be noted J MRJ-AED\R49S1~ S3.wpd
