The Integrated Flue Gas Treatment (IFGT) system is a new concept whereby a Teflon covered ® condensing heat exchanger is adapted to remove certain flue gas constituents, both particulate and gaseous, while recovering low level heat. The pollutant removal performance and durability of this device is the subject of a USDOE sponsored program to develop this technology. The program was conducted under contract to the United States Department of Energy's Fossil Energy Technology Center (DOE-FETC) and was supported by the Ohio Coal Development Office (OCDO) within the Ohio Department of Development, the Electric Power Research Institute's Environmental Control Technology Center (EPRI-ECTC) and Babcock and Wilcox -a McDermott Company (B&W).This report covers the results of the first phase of this program. This Phase I project has been a two year effort. Phase I includes two experimental tasks. One task dealt principally with the pollutant removal capabilities of the IFGT at a scale of about 1.2MW . The other task studied the t durability of the Teflon covering to withstand the rigors of abrasive wear by fly ash emitted as a ® result of coal combustion.The pollutant removal characteristics of the IFGT system were measured over a wide range of operating conditions. The coals tested included high, medium and low-sulfur coals. The flue gas pollutants studied included ammonia, hydrogen chloride, hydrogen fluoride, particulate, sulfur dioxide, gas phase and particle phase mercury and gas phase and particle phase trace elements. The particulate removal efficiency and size distribution was investigated. These test results demonstrated that the IFGT system is an effective device for both acid gas absorption and fine particulate collection. Although soda ash was shown to be the most effective reagent for acid gas absorption, comparative cost analyses suggested that magnesium enhanced lime was the most promising avenue for future study.The durability of the Teflon covered heat exchanger tubes was studied on a pilot-scale single-® stage condensing heat exchanger (CHX ). This device was operated under typical coal-fired ® flue gas conditions on a continuous basis for a period of approximately 10 months. Data from the test indicate that virtually no decrease in Teflon thickness was observed for the coating on the ® first two rows of heat exchanger tubes, even at high inlet particulate loadings. Evidence of wear was present only at the microscopic level, and even then was very minor in severity. Final Technical Report for Phase I -Revision 0 Contract DE-AC22-95PC95255ii of xv iii of xv This contract includes two phases with the second phase to be proposed after completing the first phase. Phase I testing was completed at a scale of about 1.3 MW . By comparison, the Phase II t work will be proposed at a scale of about 10 MW . The purpose of this report is to present the t results of the Phase I tests.The purpose of Phase I of this contract was to determine the pollutant removal performance and the anticipated wear life of...
