【 摘 要 】

To minimize program cost, additional testing was performed in concert with EPRI-funded testing at the Coal Flow Test Facility in late July. The major focus of this effort was noise reduction. As it turned out, the main source of the noise proved to be related to electrical grounding issues and the adjustments needed to address these problems took most of the test period. Once those changes were in place, a very limited quantity of high quality data was obtained and an excellent correlation between the dynamic signature and coal flow was obtained. Additional data were then collected during August. Unfortunately, the sensor signal for the August data collection proved to be extremely weak. Therefore, Airflow Sciences will collect additional laboratory data in October before proceeding with the collection of field data. This will allow the calibration to be expanded to include a wider range of flow conditions and improve the potential applicability to data to be collected at the coal plants.
