Performance evaluation of a cross flow filter on a subpilot-scale pressurized fluid bed coal combustor. Final report.

摘要

The design, installation and testing of a 15-element (1200 acfm) cross flow filter unit at the New York University (NYU) Pressurized Fluidized Bed Combustion (PFBC) facility was completed. The facility is located at the Antonio Ferri Laboratory in Westbury, New York and operated by the NYU staff as a high temperature, high pressure (HTHP) particle control test system. The Westinghouse filter system utilized the 12 (times) 12 (times) 14 inch mid-rib bond cross flow filter elements manufactured by Coors Ceramics Company. The test unit consisted of five filter modules each containing three filter elements. During operation, each module was cleaned online by the reverse pulse jet method. The ability of the cross flow filter to operate stably in the PFBC environment and collect ash particles was evaluated in two nominally 50-hour continuous test runs. The particle filtration performance of the filter system was determined from isokinetic grab and cascade impactor sampling. In PFBC application, the high temperature particle control device must protect the gas turbine expander blades from particle erosion and deposition damage and provide sufficient cleanup to meet environmental emission standards. 6 refs., 29 figs., 22 tabs.
