    Abstract: Provided are apparatus and methods of gasification using a circulating fluidized bed reactor comprising a separate pyrolysis reaction chamber, one or more primary char gasification chambers, and one or more secondary char gasification chambers which comprise an internal vertical reaction volume suitable for containing a particle bed fluidized by a predominantly vertical upwards gas flow. The vertical reaction volume is advantageous in that this provides the possibility for increased retention time of particles, facilitating comparatively slow "productive" temperature moderation based on endothermic char conversion.

    Abstract: A combustor (110) is operative to effect therewith the combustion of fossil fuel (114') in order to thereby both heat to a working fluid (102) and generate a flue gas (104). An air preheater 144 receives the flue gas 104 generated in the combustor (110). A blower (180) causes air (188) to flow to the air preheater (144) when operating in an air fired mode, and causes both O2 and recycled flue gas 188' to flow when operating in the O2 firing mode. The air preheater (144) is operative to transfer heat from the flue gas (150) received thereby to the air 188 that is received when operating in an air fired mode or to both the received O2 and the recycled flue gas (188') that is received when operating in the O2 firing mode in order to thereby effect a preheating of the air (188) or of both the O2 and recycled flue gas, (188') depending upon the specific nature of the mode of operation thereof, and to thereby effect therewith a cooling of the flue gas received thereby. The preheated air (142) or both the preheated O2 and the recycled flue gas (142'), depending upon the specific nature of the mode of operation, is caused to flow from the air preheater (144) to the combustor (110) in order to thereby effect therewith a fluidization of the fossil fuel (114').

    Abstract: A combustor 110 combust a fluidized bed of fossil fuel 114, 114' to heat a working fluid 102 and generate flue gas 104. An air preheater 144 has first and second gas passageways 144a, 144b for respectively directing the generated flue gas 150 and another gas 250 with captured CO2 generated by combustion outside of the combustor 110. When operated in a non-CO2 capture, the air preheater 144 receives the flue gas 150, but not the other gas 250, and the first gas passageway 144a directs the flue gas 150 so as to preheat the air 188. However, when operated in the CO2 capture mode, the air preheater 144 receives the flue gas 150 and the other gas 250, and the second gas passageway 144b also directs the other gas 250 so as to preheat the air 188'. In either mode, the preheated air 188, 188' is applied by the combustor 110 to fluidize a bed of fossil fuel 114, 114'.
