PRESSURIZED FLUIDIZED BED COMBUSTOR WITH FUEL CELL CO2 CAPTURE

摘要

Systems and methods for generating electrical power combine pressurized fluidized bed combustors (PFBC) and molten carbonate fuel cells (MCFC) to provide a low cost solution for electricity generation with CO2 capture. A solid fuel is introduced fuel into a pressurized fluidized bed combustor to produce steam, a first quantity of electrical power, and a flue gas including CO2. Air, natural gas, at least a portion of the steam and at least a portion of the flue gas including CO2 are introduced to a molten carbonate fuel cell to produce a second quantity of electrical power and an output stream comprising primarily CO2. The pressurized fluidized bed combustor can desirably be air-fired and the solid fuel introduced there into can desirably be in a finely pulverized form.
