The objective of this program is to evaluate the performance and operating characteristics of the cross flow filter on a coal fired, pressurized, fluidized bed combustor (PFBC). This data will also be used to evaluate the economic feasibility of the cross flow filter concept in a PFBC system. The tests will be carried out utilizing the existing New York University (NYU) subpilot scale PFBC. The filter unit will be a multi-element configuration that will be operated for about 200 hours at conditions to demonstrate particle removal capability to levels required for meeting power plant New Source Performance Standards and/or economic plant operation. The program is composed of two major technical tasks. Task 1 is directed at the design and actual test of the cross flow filter system at the DOE subpilot-scale PFBC test facility located at NYU. The second task is intended to integrate the results of the first task in a conceptual design and cost analysis such that proper economic perspective for the filter concept can be gained. Contents of this report includes: overall program objectives; system configuration and design; test plan development; success/failure criteria; and extrapolation techniques and algorithms. 6 figs., 2 tabs.
