    摘要: A gasifier 10 includes a first chemical process loop 12 having an exothermic oxidizer reactor 14 and an endothermic reducer reactor 16. CaS is oxidized in air in the oxidizer reactor 14 to form hot CaSO4 which is discharged to the reducer reactor 16. Hot CaSO4 and carbonaceous fuel received in the reducer reactor 16 undergo an endothermic reaction utilizing the heat content of the CaSO4, the carbonaceous fuel stripping the oxygen from the CaSO4 to form CaS and a CO rich syngas. The CaS is discharged to the oxidizer reactor 14 and the syngas is discharged to a second chemical process loop 52. The second chemical process loop 52 has a water-gas shift reactor 54 and a calciner 42. The CO of the syngas reacts with gaseous H2O in the shift reactor 54 to produce H2 and CO2. The CO2 is captured by CaO to form hot CaCO3 in an exothermic reaction. The hot CaCO3 is discharged to the calciner 42, the heat content of the CaCO3 being used to strip the CO2 from the CaO in an endothermic reaction in the calciner, with the CaO being discharged from the calciner 42 to the shift reactor 54.

    摘要: A temperature measuring device for a gasifier of a gasifier system wherein the gasifier has a through opening formed thereon. The temperature measuring device includes a slag shield mounted on the gasifier so that a portion of the slag shield extends into the interior of the gasifier through the opening with which the gasifier is provided for this purpose, and a temperature measuring instrument mounted in supported relation within the slag shield so that a line-of-sight exists from the temperature measuring instrument into the interior of the gasifier whereat the temperature is desired to be measured. The slag shield is designed to protect the temperature measuring instrument from the slag flow within the gasifier. The temperature measuring instrument further includes cooling means for cooling at least that portion of the slag shield that extends into the interior of the gasifier, and purge gas means for supplying a flow of purge gas in surrounding relation to the temperature measuring instrument to purge particulate matter therefrom in order to ensure that the line-of-sight between the temperature measuring instrument and the interior of the gasifier remains unobscured.

    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′.

    摘要: A high performance, multi-stage, pressurized, airblown, entrained flow coal gasifier system and a method of operating such a gasifier system for generating therewithin fuel gas from coal. The subject gasifier system includes an outer, pressure containing vessel surrounding an inner, water-cooled vessel wherein the gasification reaction, through which the fuel gas is generated from coal, takes place. The inner, water-cooled vessel embodies a first stage within which the high temperatures required for the gasification reactions to take place as well as for slagging are generated from the combustion of char, a second stage within which the char is gasified to generate the subject fuel gas, and a third stage within which coal is devolatilized to produce the char for the first stage and the second stage and with a concomitant quenching being effected of the fuel gas as the latter flows through the third stage of the inner water-cooled vessel.
