Book Description
The objective of this program is to evaluate the design and obtain operating experience for up to two advanced particle filter (APF) systems through long-term testing on a slip stream at Ohio Power Company's Tidd PFBC Demonstration Plant. Performance and reliability of commercial-scale filter modules will be monitored to aid in an assessment of the readiness and economic viability of this technology for commercial PFBC applications. The engineering, and design of the hot gas piping systems modifications were completed during the summer of 1992, and in September, 1992 reassembly of the pipe sections began at Tidd. The HGCU system will be commissioned with the APF in October, 1992. Present plans are to operate the APF system throughout the rest of the Tidd three-year test program which is scheduled to end in February, 1994.

Book Description
This is the thirteenth Technical Progress Report submitted to the Department of Energy (DOE) in connection with the cooperative agreement between the DOE and Ohio Power Company for the Tidd PFBC Hot Gas Clean Up Test Facility. This report covers the period of work completed during the Fourth Quarter of CY 1992. The following are highlights of the activities that occurred during this report period: Initial operation of the Advanced Particle Filter (APF) occurred during this quarter. The following table summarizes the operating dates and times. HGCU ash lockhopper valve plugged with ash. Primary cyclone ash pluggage. Problems with the coal water paste. Unit restarted warm 13 hours later. HGCU expansion joint No. 7 leak in internal ply of bellows. Problems encountered during these initial tests included hot spots on the APP, backup cyclone and instrumentation spools, two breakdowns of the backpulse air compressor, pluggage of the APF hopper and ash removal system, failure (breakage) of 21 filter candles, leakage of the inner ply of one (1) expansion joint bellows, and numerous other smaller problems. These operating problems are discussed in detail in a subsequent section of this report. Following shutdown and equipment inspection in December, design modifications were initiated to correct the problems noted above. The system is scheduled to resume operation in March, 1993.

Book Description
This is the sixteenth Technical Progress Report submitted to the Department of Energy (DOE) in connection with the cooperative agreement between the DOE and Ohio Power Company for the Tidd PFBC (pressurized fluidized-bed combustion) Hot Gas Clean Up Test Facility (HGCU). This report covers the period of work completed during the Third Quarter of CY 1993. During this quarter, the Advanced Particle Filter (APF) was operated for a total of 1295 hours. This represents 58% availability during July, August, September, and including June 30 of the previous quarter. The operating dates and times since initial operation are summarized. The APF operating temperatures and differential pressures are provided. Details of the APF runs during this quarter are included in this report.

Book Description
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.

Book Description
During this quarter, the Tidd Hot Gas Clean Up System completed a 691-hour test run which began during the third quarter. Table 1 summarizes all test runs since initial operation. Following this test run the system was shut down and the filter opened for inspection and recandling. The system remained out of service during the remainder of the quarter. In addition to monitoring and evaluating the performance of the HGCU system during testing, engineering effort was devoted to posttest inspection of the APF (Advanced Particle Filter) and evaluation of the effects of totally spoiling the primary cyclone. In addition, the authors worked with Westinghouse in the selection of replacement candles that were installed during the fourth quarter. During the unit outage this quarter, the primary cyclone upstream of the APF was modified to force all of the ash to pass through the cyclone and enter the APF without using spoiling air. Appendices to this report describe the dust shroud support strap design; an analysis of the effect of support-transferred vibrations on the failure of ceramic candle filters; the Tidd APF operation; the Tidd APF boroscope inspection; a general inspection of Tidd filter internals; tally of Tidd filters; ash formations in the W-APF-October 1994 post-test inspection; characterization of the as-manufactured and PFBC-exposed 3M CVI-SiC composite filter matrix; strength characterization of the first and second generation candle filters after 1,705 hours of PFBC operation at Tidd; and filters used in the December 1994 recandling effort at Tidd.

Book Description
This is the eleventh technical progress report submitted to the Department of Energy (DOE) in connection with the Cooperative Agreement between DOE and Ohio Power company for the Tidd Pressurized Fluidized Bed Combustion (PFBC) Hot Gas Clean Up Test Facility. This report covers the period of work completed during the Second Quarter of CY 1992. Activities included: The Tidd combustor internals were modified to connect the hot gas system for slipstream operation; Various pre-operational activities were completed, including pneumatic leak testing of the HGCU system, operation of the closed cycle cooling water system, operation of the back pulse compressor and air preheater, and checkout of the back pulse skid. Initial operation of the system using the bypass cyclone occurred during May 21--23, 1992; On May 23, 1992, an expansion joint ruptured, forcing the unit to be shut down. The failure was later determined to be due to stress corrosion. Following the expansion joint failure, a complete engineering review of the system was undertaken and is continuing; Contract Modification No. 6 was issued to Westinghouse during this quarter. This modification is for APF surveillance testing services; A purchase order was issued to Battelle for ash sampling hardware and testing services.
