摘要： An oxygen fired fluidized bed combustor system (Oxy-FBC) is provided. The system provides means of producing a nearly pure stream of carbon dioxide for storage at high efficiency by controlling the oxygen content within certain regions of the combustor to control the rate of heat release allowing efficient transfer of heat from the combustor to the boiler tubes while avoiding excessively high temperatures that will cause ash melting, and simultaneously remove sulphur from the combustor via sorbents such as limestone and dolomite. The present invention utilizes a coarse oxygen carrier bed material to distribute heat and oxygen throughout an Oxy-FBC, while injecting fine sulphur sorbent that will continuously be removed from the bed.

摘要： A chemical looping combustion (CLC) process for sour gas combustion is integrated with a gas turbine combined cycle and a steam generation unit, and is configured to provide in-situ removal of H2S from the sour gas fuel by reacting the H2S with a oxygen carrier at a location within the fuel reactor of the CLC unit. The process is also configured such that oxygen-rich exhaust gases from the gas turbine combined cycle is used to feed the air reactor of the CLC unit and re-oxidize oxygen carriers for recirculation in the CLC unit.

摘要： Methods and devices for combusting a carbonaceous fuel in an oxy-combustion fluidized bed reactor involving controlling the local oxygen content within the oxy-combustion reactor to specified levels. The carbonaceous fuel and an oxygen-containing gas are introduced into a fluidized bed reactor and eluted through a fluidized bed of an inert material, dolomite or a combination thereof to combust the fuel and oxygen to produce at least CO2 and steam. The oxygen-containing gas is a mixture of oxygen, recycled CO2 and steam and has sufficient oxygen added to the recycled CO2 and steam that the mixture contains 7-20 mole % oxygen. The carbonaceous fuel and the oxygen-containing gas are introduced into the fluidized bed at a location in sufficiently close proximity to each other to avoid producing a reducing atmosphere at the location. At least a portion of the produced CO2 and steam are recycled to the reactor.

摘要： The invention relates to a method and to a plant for chemical looping oxidation-reduction combustion (CLC) of a gaseous hydrocarbon feed, for example natural gas essentially containing methane. According to the invention, catalytic reforming of the feed is performed within the reduction zone where combustion of the feed is conducted on contact with an oxidation-reduction active mass in form of particles. The reforming catalyst comes in form of untransported fluidized particles within the reduction zone. The catalyst thus confined in the reduction zone does not circulate in the CLC loop.

摘要： A dual phase fuel feeder is disclosed that can be used to provide both solid fuels and liquid fuels to a boiler, such as a fluidized bed boiler. The fuel feeder includes a sloped chute which defines a solid feedpath. Gas distribution nozzles are located at the base of the fuel feeder, and secondary nozzles are located so as to be able to distribute a liquid or particulate fuel into the solid feedpath. This permits the liquid fuel to contact the solid fuel and be carried into the fluidized bed instead of becoming suspended above the bed.

摘要： The invention relates to a method and to a device for chemical looping combustion CLC of a solid hydrocarbon feed wherein it is proposed to inject the solid hydrocarbon feed so as to limit any occurrence of sticking of the feed to the walls of the injection device. The solid feed is fed into a conveying zone operating under fluidized bed conditions and opening into a combustion reactor. A fluidization gas is injected into this conveying zone while controlling the flow of gas in such a way that the superficial velocity of the gas in the conveying zone is higher than the terminal velocity of the solid hydrocarbon feed particles and the terminal velocity of solid particles present in the combustion reactor, and while controlling the fluidization gas temperature in such a way that the temperature in the conveying zone is less than or equal to 500° C.
