INTEGRATED SYSTEM TO CONTROL PRIMARY PM 2.5 FROM ELECTRIC POWER PLANTS
The performance tests at E.C. Gaston showed how the Advanced ElectroCore field prototype performance changed as a function of the gas flow, inlet loading and the voltage applied to the central electrode in the separator. With the optimum voltage applied to the electrode, the unit achieved a maximum efficiency of 96.38 percent and a minimum outlet loading of 0.0021 grains/dscf while operating with a specific separating area (SSA) of 100 square feet per thousand acfm. The minimum outlet loading translates to about 0.00575 lb{sub m}/million Btu or less than one fifth of the current NSPS standard of 0.03 lb{sub m}/million Btu. The highest efficiency for the upstream ESP was about 99.75 percent. Together these two systems are capable of removing 99.991 percent of the particulate matter coming from the uncontrolled boiler. This efficiency is higher than the target efficiency of 99.99 percent and the outlet loading of 0.00575 lb{sub m}/million Btu is almost half of the target emission rate of 0.01 lb{sub m}/million stated in the program objectives. In terms of efficiency and outlet concentration, the tests showed that the Advanced ElectroCore can meet or exceed the program goals. The mercury capture tests were conducted using the Ontario Hydro method. When injection activated carbon at the rate of 7 pounds per million cubic feet of gas, the measured removal efficiency was about 90 percent. At the time of this writing, LSR was unable to obtain the full report on the mercury testing. If it does become available, it will be included as an appendix to this report. The results show that the ElectroCore has been successfully scaled up by a factor of 12 from the 500 acfm unit tested at Alabama Power Company's Plant Miller in the summer of 1997. The addition of the central electrode has improved the separation efficiency when inlet loadings get very low.
