Integrated low emissions cleanup system for direct coal fueled turbines: (moving bed, fluid bed contactor/ceramic filter). Thirtieth quarterly report for the period January--March 1995
The United States Department of Energy, Morgantown Energy Research Center (DOE/METC), is sponsoring the development of advanced, coal-fueled turbine power plants such as pressurized fluid bed combustion and coal gasification combined cycles. A major technical challenge remaining for the development of the coal-fueled turbine is high-temperature gas cleaning to meet environmental standards for sulfur oxides and particulate emissions, as well as to provide acceptable turbine life. The Westinghouse Electric Corporation, Science & Technology Center, is evaluating Integrated Low Emissions Cleanup (ILEC) concepts that have been configured to meet this technical challenge. These UEC concepts simultaneously control sulfur, particulate, and alkali contaminants in the high-pressure process gases. This document reports the status of a program in the thirtieth quarter to develop this ILEC technology. During this Quarter of the program, the Phase In bench-scale, high-temperature, high-pressure (HTHP) testing of PFBC fly ashes was continued. Tests have been completed to characterize the filter cake pulse cleaning, as a function of temperature. The behavior trends are consistent with field unit observations. Sulfur removal tests, looking at the influence of SO{sub 2} on filter cake permeability, as well as the ability to remove sulfur by injecting dolomite into the filter, have been completed. Alkali removal tests were initiated this quarter injecting emathlite into the filter. A complete summary of the test procedures; tests completed and test results is presented in Appendices A, B and C. Preparation has been made to prepare the Phase III final report.
