Laboratory/Bench Scale Testing and Evaluation of A.P.T. Dry Plate Scrubber. Fifty Third Monthly Report, July 1-31, 1984

摘要

The objective of this project is to conduct a bench scale experimental evaluation of the dry plate scrubber (DPS) at high temperature and pressure to determine its potential for controlling particulate and alkali vapor emissions from PFBC processes. The technical objective for July was to: continue DPS experiments to study ash cake accumulation phenomenon. The remaining test program on the HTP-DPS experiments will start after completing the ash cake accumulation experiments. The test plan for the remaining experiments was outlined and presented in the last monthly technical report. The HTP-DPS experiments will be performed with either alumina collectors or zirconia collectors. We have recommended zirconia collectors. This involves an increase in cost and this cost was submitted during the month. The work on the process design will be continued after completing the HTP-DPS experiments described above. It is anticipated that the above test plan will provide information on collector feed rates and collector to stone ratio for optimum system design. During this reporting period, two tests (Run No. 52/03 and 53/01) were completed to establish baseline ash accumulation characteristics. One test (Run No. 52/02) was performed to obtain the temperature profile of gas stream after replacing the heaters. The test conditions and data analysis for these three runs are presented and the test procedure is briefly described. (ERA citation 09:049385)
