    摘要: A fossil fuel fired combustion apparatus and a method for operating the fossil fuel fired combustion apparatus are provided which offer the flexibility to use carbon dioxide (CO2) both as a desirable end product and as support to the combustion process. The method includes the step of introducing a substantially pure oxygen feed stream into the fossil fuel fired combustion apparatus and the step of combusting a fossil fuel in the presence of the substantially pure oxygen feed stream to produce a flue gas having carbon dioxide and water vapor as its two largest constituent elements by volume. The method also includes the step of passing the flue gas through an oxygen feed stream pre-heater at which heat from the flue gas is transferred to the oxygen feed stream. Furthermore, the method includes the step of separating the flue gas into an end product portion and a recycling portion. The method additionally includes cooling and compressing the end product portion of the flue gas so as to yield carbon dioxide in a liquid phase and directing the recycling portion of the flue gas to the fossil fuel fired combustion unit to contribute to the combustion process therein.

The feed stream includes a portion of a flue gas stream generated upon combustion of the fuel in the combustion system. The flue gas stream is subjected to a carbon dioxide capture system to remove carbon dioxide therefrom and an amount of at least one of an oxygen stream or the portion of the flue gas stream introduced to the feed stream is adjusted such that the feed stream maintains an oxygen concentration in a range of between 10% to 90% by volume and the carbon dioxide capture system operates at an energy load between about 1.4 GJ/ton of carbon dioxide and about 3.0 GJ/ton of carbon dioxide.

    摘要: 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′.

    摘要: 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′.
