II. Emissions Characterization and Plume/Atmospheric Chemistry

5. Plume Study to Characterize Fine Particle Emissions and Secondary Particle Formation

As part of the IA, TVA will carry out a study of fine particle formation in the plume of Cumberland Fossil Plant before and after the planned installation of NO_x and SO₂ emissions reduction equipment. The major emphasis is to gather plume data at various distances downwind from the plant. EPRI and TVA will co-fund this effort.

6. Fine Particulate Characterization and Control for Coal-Fired Boilers

McDermott Technology (Babcock & Wilcox) will collect and characterize primary fine particulate and associated trace metal emissions from the 10 Mw_e Clean Environment Development Facility. The project is focused on the emission and potential impacts of fine carbon soot from the operation of Low-NO_x Burner technology. Co-funding from the Ohio Coal Development Office and McDermott.

III. Control Technology Research and Development

7. Advanced Hybrid Particulate Collector (AHPC)

The University of North Dakota's Energy & Environmental Research Center is developing a novel process for controlling the emission of primary fine particulates that incorporates the best features of an ESP and a bag house. A 9,000 acfm pilot-scale AHPC will be tested on the slipstream of an operating coal-fired utility boiler located in South Dakota during the summer/fall 1999.

8. Second Generation Advanced Reburning for High Efficiency NO_x Control

Energy and Environmental Research Corporation (EERC) is developing a second generation advanced reburning (SGAR) concept for high-efficiency, low-cost No_x control for coal-fired utility boilers. The SGAR technology will be scaled up from 1 × 10⁶ Btu/hr to 10 × 10⁶ Btu/hr.

9. Selective Non-Catalytic Reduction (SNCR)/ Selective Catalytic Reduction (SCR) Hybrid for NO_x Control

GPU Generation is carrying out full-scale testing of a combined SNCR/SCR system at their 147 MW_e Seward Station near Johnstown, Pa. The combination of SNCR and SCR is expected to allow GPU to achieve a NO_x emission target of below 0.40 lb/MMBtu while addressing NH₃ slip and associated ammonium sulfate deposition and fouling problems. EPRI, CONSOL, and EPA are cofunding this project.

10. Selective Non-Catalytic Reduction Field Test Program

Under a Cooperative Agreement with American Electric Power, DOE is collaborating with the State of Ohio, EPRI, and 13 other electric-utilities in the field testing of SNCR technology at AEP's 600 MW Cardinal Station in Brilliant, Ohio. This represents the largest scale demonstration of SNCR technology on a coal-fired utility boiler in the U.S.
