Process <br /> operating data were collected by CANA during each test run. <br /> 3.2 Test Schedule <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 r: <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 /> 3.3 Field Test Changes and Problems FF <br /> 3.3.1 Sampling <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 /> Probes <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. z <br /> This did not affect results, but would have resulted in the unavailabilit y of probes-for <br /> subsequent runs if no preventative measures were taken. This problem was solved by <br /> conducting inlet sampling in the uppermost 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 /> Y <br /> temperature environment are summarized below: <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 PC:DD/PCDF trains). <br /> The M26A tram was not used for HCI, and particular matter sampling was <br /> conducted with the metals train. <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.
