F y:: <br /> Emission Test Report <br /> EMC WA-2-08 <br /> Section 4 <br /> Revision; 0 <br /> Date:September 30, 1999 <br /> Page 3 of 9 <br /> was in progress. Each integrated gas sampling apparatus was leak checked before and after <br /> each test run. <br /> 4,1.4 Determination of Moisture content <br /> Method 4 in A ppe ndix A of 40 CFR 60, inco rpo rat ed as part of Methods 23,25A,and <br /> 29,was used to determine the moisture(water vapor)content of the g as stream. Moisture <br /> collected during sampling was determined gravimetrically from the difference between the <br /> initial and final weights of all of the impingers in a train,including the resin cartridge, <br /> where used. <br /> ••3 <br /> 4,1.5 Sampi 1 ng for PCDDs and PC DFs <br /> Method 23 in Appendix A of 40 CFR 60(basis for SOP MRI-8404 was used t P } o <br /> collect samples for dioxin and furan analysis. Clarifications of and modifications atzons to the <br /> method are included in the following discussion. <br /> c � 4 <br /> a <br /> Quartz glass nozzles and probe liners were used in water-cooled p robes. The internal <br /> surface of the compression fittings used for connecting nozzles to probe liners are <br /> permanently coated with abrasion-resistant Teflon to revert sample as contact with the <br /> ar P p g <br /> stainless steel,and the connections are positioned within the water-cooled section of each <br /> x probe. <br /> r <br /> Heat traced, 1/2-inch O.D. with I/a-inch wall Teff on@ tubing was used as a sample <br /> . P <br /> transfer line(STL)between the probe liner outlet and the filter holder inlet in all of the <br /> trains because the proximity of adjacent test Po rts and other obstructions would not allow <br /> sampling with trains assembled in the normal manner. A glass coupling was used to <br /> connect the STL tubing to the probe liner outlet while the other end of the tube was <br /> connected directly to the filter holder inlet. The STL was maintained at 248±25°F during <br /> sampling. Samples were recovered from the STL in the same manner as for the probe,as <br /> 3 specified in Method 23. <br /> No cyclone/flask assembly as necessary in front of the filter holder <br /> y �y to prevent <br /> overloading the filter. Filter supports in the filter holders were Teflon @-coated, stainless <br /> steel screening. Quartz fiber filters having the same specifications described in the method <br /> were used. Each cartridge (sorbent trap)was loaded with approximately 65 grams of <br /> XAI3--2 resin. <br /> i <br /> N Two silica gel impingers were used in each train. This was done to minimize an <br /> y need <br /> to swap those components during a test run. <br /> MM-AM%495 1-08-03 54.wo <br />
