20110229835 | DEVICE FOR BURNING A FUEL/OXIDANT MIXTURE - A device for burning a fuel/oxidant mixture in a strongly exothermic reaction, consists of a reactor with a combustion chamber containing at least one first porous material and at least one second porous material in separate zones A and C. The zones are designed in such a way that an exothermic reaction can only occur in zone B, and with one or more feed lines for the fuel and for the oxidant, whereby zone A, which consists of the first porous material, is separated by a distance of approximately 10 mm to 4000 mm, for example approximately 20 mm to 500 mm, equating to one zone B, from zone C which consists of the second porous material and is located before zone C in a flow direction of the fuel/oxidant mixture. | 09-22-2011 |
20120214109 | FLUIDIZING NOZZLE WELD COLLAR - A unique nozzle [20] for a fluidized bed reactor is described that may be replaced efficiently. This employs a collar [30, 130, 230] attached to a vertical section [15] of a feed pipe [11] that provides fluidizing gases. The vertical section [15] has a plurality of nozzle openings [17] at its upper end. A nozzle cap [19] fits over the upper end of the vertical section [15] and the nozzle openings [17]. The collar [30, 130, 230] extends radially outward from the vertical section [15] at a location just below the nozzle cap [19] supporting it in its operational position. During replacement of the vertical section [15] and the nozzle cap [19], the collar acts as a guide to direct cutting equipment to the proper location and facilitate proper cuts. The collar [30, 130, 230] also acts as a support to hold the vertical section [15] and the nozzle cap [19] in proper position to facilitate welding. | 08-23-2012 |
20140072917 | SYSTEMS FOR CONVERTING FUEL - A system for converting fuel may include a first moving bed reactor, a second reactor, and a non-mechanical valve. The first moving bed reactor may include at least one tapered section and multiple injection gas ports. The multiple injection gas ports may be configured to deliver a fuel to the first moving bed reactor. The first moving bed reactor may be configured to reduce an oxygen carrying material with a fuel by defining a countercurrent flowpath for the fuel relative to the oxygen carrying material. The second reactor may communicate with the first moving bed reactor and may be operable to receive an oxygen source. The second reactor may be configured to regenerate the reduced oxygen carrying material by oxidation. | 03-13-2014 |

20140295361 | OXYGEN CARRYING MATERIALS - In accordance with one embodiment of the present disclosure, an oxygen carrying material may include a primary active mass, a primary support material, and a secondary support material. The oxygen carrying material may include about 20% to about 70% by weight of the primary active mass, the primary active mass including a composition having a metal or metal oxide selected from the group consisting of Fe, Co, Ni, Cu, Mo, Mn, Sn, Ru, Rh, and combinations thereof. The oxygen carrying material may include about 5% to about 70% by weight of a primary support material. The oxygen carrying material may include about 1% to about 35% by mass of a secondary support material. | 10-02-2014 |
20150010873 | Chemical Looping Combustion Method And Apparatus For Solid Fuels Using Different Oxygen Carriers - A chemical looping combustion apparatus for solid fuels using different oxygen carriers is provided. The chemical looping combustion apparatus includes: a solid fuel chemical looping combustor configured to receive solid fuels and to produce carbon dioxide and steam by combustion of the solid fuels; a gaseous fuel chemical looping combustor configured to receive gaseous fuels and to produce carbon dioxide and steam by combustion of the gaseous fuels; and a devolatilization reactor configured to produce solids and gases by devolatilizing the solid fuels, and the solid fuels received by the solid fuel chemical looping combustor and the gaseous fuels received by the gaseous fuel chemical looping combustor are the solids and the gases produced by the devolatilization reactor, respectively.
