EVALUATION OF A PRESSURIZED-FLUIDIZED BED -COMBUSTION (PFBC) COMBINED CYCLE POWER PLANT CONCEPTUAL DESIGN FINAL REPORT TRADE-OFF STUDIES SUBTASK 1.3

摘要

The results of this program indicate that pressurized fluidized bed combustion systems, operating in a combined cycle power plant, offer great potential for producing electrical energy from high sulfur coal within environ¬mental constraints, at a cost less than conventional power plants utilizing low sulfur coal or flue gas desulfurization (FGD) equipment, and at higher efficiency than conventional power plants.nAs a result of various trade-off studies, a 600 MWe combined cycle arrangement incorporating a PFB combustor and supplementary firing of the gas turbine exhaust in an atmospheric fluidized bed (AFB) steam generator has been selected for detailed evaluation.
