Preliminary assessment of alternative atmospheric fluidized-bed-combustion power-plant systems. Final report
This report presents a technical and economic evaluation of alternative atmospheric fluidized-bed combustion (AFBC) power plant systems with nominal capacities of 1000 MWe. Both eastern and western coal-fired power plants are evaluated for the following systems: baseline AFBC power plants with limestone beds; AFBC power plants with inert beds and wet FGC systems; AFBC power plant with inert beds and a dry FGD system (western coal only); AFBC power plants with limestone beds and limestone precalcination; AFBC power plants with limestone beds and agglomeration and recycle of spent solids; AFBC power plant with limestone beds and sorbent regeneration (eastern coal only); and reference pulverized coal-fired (PCF) power plants with wet FGC systems. The eastern coal-fired plants burn Illinois bituminous coal with a higher heating value of 10,1000 Btu/lb and a sulfur content of 4%. The western coal-fired plants burn Wyoming subbituminous coal with a higher heating value of 8020 Btu/lb and a sulfur content of 0.48%. The capital and operating cost estimates are based on boiler designs developed by Babcock and Wilcox, Inc., and on sorbent requirements estimated by Westinghouse R and D Center. Sorbent requirements for the baseline AFBC power plants are based on a calcium to sulfur mole ratio of 5:1 for the eastern coal-fired plant and 0.7:1 for the western coal-fired plant. The Ca/S mole ratio for the western coal plant allows for 30 percent utilization of the alkaline coal ash to reduce sorbent requirements to the fluidized bed combustor. The economic analyses are based on a plant located in the East Central region of the United States with a 30-year life and a 70 percent capacity factor.
