Process <br />operating data were collected by CANA during each test run. <br /> <br />3.2 Test Schedule <br /> <br />I <br />I <br /> <br />Testing began June 11 and continued through June 17, 1999. Table 3-3 presents the <br />test run times. Testing was preceded by preliminary velocity measurements. Once <br />preliminary measurements were completed and final preparations were in progress, the site <br />coordinator and other personnel were notified of run start times. <br /> <br />3.3 Field Test Changes and Problems <br /> <br />B <br />,J <br />L~' <br />;Co.. <br /> <br />3.3.1 Sampling <br /> <br />Problems encountered in the field fell into three main categories: probes, <br />thermocouples, and sample recovery. They are discussed below. Sampling data sheets and <br />computer generated MM5 data are found in Appendices C and D. <br /> <br />-.,,,, <br />" <br />, <br />,J <br /> <br />Probes <br /> <br />Even with water-cooled probes, the extreme temperatures at the scrubber inlet caused <br />some probes to heat and warp, thereby rendering them useless for any subsequent runs. <br />This did not affect results, but would have resulted in the unavailability of probes for <br />subsequent runs if no preventative measures were taken. This problem was solved by <br />conducting inlet sampling in the uppennost port so that probes were oriented on a <br />downward slope to maintain cooling water at the tip thereby preventing heat warpage. One <br />additional port had to be installed in order to perform all inlet sampling on a downward <br />slope. Problems with sample collection as a result of using water-cooled probes in the high <br />temperature environment are summarized below: <br /> <br />n,.. <br />u <br /> <br />r] <br />f,., <br /> <br />,- <br /> <br />· The additional port was installed after the fourth run. Only two trains were <br />operated during Run 4 in the two available ports (metals and PCDDIPCDF trains). <br />The M26A train was not used for HCI, and particular matter sampling was <br />conducted with the metals train. <br /> <br />u <br /> <br />· During Run 4, sampling at the inlet continued during port changes at the outlet. <br />This resulted in longer sampling times at the inlet than at the outlet. For all <br />subsequent runs sampling at the inlet was halted until port changes at the outlet <br />were completed to obtain simultaneous inlet/outlet sample collection.
