Book excerpt: Effective high temperature ceramic filters are indispensable in the advanced, coal based power systems (IGCC and PFBC). To meet the environmental particulate emission requirements and improve thermal efficiency, ceramic filters are utilized to cleanup the hot gas particulate to protect downstream heat exchanger and gas turbine components from fouling and corrosion. The mechanical integrity of ceramic filters and an efficient dust cake removal system are the key issues for hot gas cleanup systems. The filters must survive combined stresses due to mechanical, thermal, chemical and steam attack throughout normal operations (cold back pulse cleaning jets), unexpected excessive ash accumulation, and the start up and shut down conditions. To evaluate the design and performance of ceramic filters, different long term filter testing programs were conducted. To fulfill this purpose, two Advanced Particle Filter (APF) systems were complete at Tidd PFBC Demonstration Plant in Brilliant, Ohio in late 1990 as part of the Department of Energy's (DOE) Clean Coal Technology Program. However, many filter failures 1649 were reported prior to its desired life time. In Tidd APF vessel, 28 filters failed one time, The objectives of this program were to provide an understanding of the factors pertinent to the failures of ceramic filters by characterizing filter properties and the dust cake removal mechanism, Researches were emphasized on understanding of changes of filter properties and back pulse cleaning mechanism to resolve the issues relating to filter permeability variations, ash bridging and micro-thermal cracks induced during cold back pulse cleaning. To perform failure analysis of ceramic filters, thermal numerical simulation, material laboratory analysis on filter materials and dust cake, and measurements on filter properties and back pulse intensity along filter axis within a bench scale filter chamber were conducted.

This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced integrated gasification combined cycle (IGCC) and pressurized fluidized bed combustion (PFBC) power system requires both hot gas desulfurization and particulate filtration to improve system thermal efficiency and overall performance. Therefore, effective high temperature ceramic filters are indispensable key component in both of the advanced IGCC and PFBC coal based power systems to perform hot gas cleanup work. To meet the environmental particulate emission requirements and improve thermal efficiency, ceramic filters are mainly utilized to cleanup the hot gas particulate to protect downstream heat exchanger and gas turbine components from fouling and corrosion. The mechanical integrity of ceramic filters and an efficient dust cake removal system are the key issues for hot gas cleanup systems. The filters must survive combined stresses due to mechanical, thermal, chemical and steam attack throughout normal operations (cold back pulse cleaning jets), unexpected excessive ash accumulation, and the start up and shut down conditions. To evaluate the design and performance of ceramic filters, different long term filter testing programs were conducted. To fulfill this purpose, two Advanced Particle Filter (APF) systems were complete at Tidd PFBC Demonstration Plant, in Brilliant, Ohio in late 1990 as part of the Department of Energy's (DOE) Clean Coal Technology Program. But the most undesirable thing ever happened was the sudden functional and physical failures of filters prior to its designed life time. In Tidd APF filter vessel, twenty eight (28) filters failed one time. Significant research effort has been carried out to find out the causes that led to the early failure of filters. In this work, the studies are emphasized on the possible failure causes analysis of rigid ceramic candle filters. The objectives of this program were to provide an systematic study on the characterization of filters, material laboratory analysis on filter micro-structure, the dust cake dislodging mechanism and possible causes led to failures of ceramic filters. These research work includes 1) characterization on filter properties, 2) material laboratory investigation on cracked and un-cracked filter batches, 3) a thermal numerical simulation, 4) various physical testing on filter mechanical integrity and 5) the back pulse cleaning mechanism. These studies provide insights into variations of filter permeability, filter toughness against different mechanical loading impact, microstructure changes of filters, coal ash bridging and micro-thermal cracks induced during the cold back pulse cleaning process. To characterize the physical properties of used and unused ceramic filters, filter permeabilities and the pressure field of the gas stream were measured within a filter chamber with the use of fast response pressure transducers and an automatic data acquisition system. Used filters displayed non-uniform permeability distribution along its axis; and these variations developed asymmetric flow pattern in the filter chamber.

Quarterly Report, July 1--September 30, 1997 written by and published by . This book was released on 1997 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research activities performed at PV A and M University in the third quarter of 1997 are summarized within. PV A and MU had performed mechanical and back pulse testing to characterize the performance of the filter and is using the process of elimination to perform the failure analysis for filters. The mechanical testing performed on the filters are categorized as follows: the acceleration testing; the vibration testing; the air jet impulse testing; and the impact testing. The major work completed in the third quarter, 1997 for filter back pulse cleaning testing included the following items: (1) the completion of the test system; (2) the procurement of particulate sample; (3) the development of a data acquisition system; (4) the filtration pressure field monitoring with the use of micro-fast pressure sensor assembly; (5) the design of a back pulse system; (6) completed a back pulse cleaning test plan; and (7) started performing parametric testing on particulate removal. The bulk of this report consists of a user's manual for the automatic testing on instrumentation interfacing.
