PFBC HGCU test facility technical progress report. First Quarter, CY 1994
This is the eighteenth Technical Progress Report submitted in connection with the cooperative agreement between the DOE and Ohio Power Company for the Tidd PFBC Hot Gas Clean Up Test Facility. During this quarter, the Tidd Hot Gas Clean Up System operated for 835 hours during six separate test runs. The system was starting into a seventh run at the end of the quarter. Highlights of this period are summarized below: the longest run during the quarter was approximately 333 hours; filter pressure drop was stable during all test runs this quarter using spoiling air to the primary cyclone upstream of the Advanced Particle Filter (APF); the tempering air system was commissioned this quarter which enabled the unit to operate at full load conditions while limiting the gas temperature in the APF to 1,400 F; during a portion of the one run, the tempering air was removed and the filter operated without problems up to 1,450 F; ash sampling was performed by Battelle personnel upstream and downstream of the APF and ash loading and particle size distribution data were obtained, a summary report is included; a hot area on the APF head was successfully repaired in service; a hot spot on the top of an expansion joint was successfully repaired by drilling holes from the inside of the pipe and pumping in refractory insulation; a corrosion inspection program for the HGCU system was issued giving recommendations for points to inspect; filter internal inspections following test runs 13 and 17 revealed a light coating (up to 1/4 inch thick) of residual ash on the candles and some ash bridging between the dust sheds and inner rows of candles. Data from these inspections are included with this report.
