NOVELTY - An injection device adaptable to transfer calcium carbonate particles for regeneration into calcium oxide, comprises an injector body having an inlet end to receive a heated air volume, and a discharge end; transfer tube(s) connectably disposed through a portion of the injector body operable to discharge the calcium carbonate particles at the discharge end; and flow nozzle(s) to receive and discharge the heated air volume at the discharge end.    USE - For transferring calcium carbonate particles for regeneration into calcium oxide.    ADVANTAGE - The inventive device reduces the nitrogen oxide (NOx) gas production and particle sintering. By circulating a particulate form of calcium oxide in the reforming system, continuous reuse of the calcium material is possible by conversion of calcium carbonate to calcium oxide and removal of the carbon dioxide gas. The steam/methane reformation process in conjunction with the inventive device allows a reduced system temperature operating condition while meeting reduced NOx and component size conditions. The flow splitter in conjunction with the inventive device permits upscaling the inventive device without increasing the quantity of calciners used to react the calcium carbonate back to calcium oxide.    DETAILED DESCRIPTION - An injection device adaptable to transfer calcium carbonate particles for regeneration into calcium oxide, comprises an injector body having an inlet end adapted to receive a heated air volume, and a discharge end (33); transfer tube(s) connectably disposed through a portion of the injector body operable to discharge the calcium carbonate particles at the discharge end; and flow nozzle(s) (72) adaptable to receive the heated air volume and discharge the heated air volume at the discharge end. The flow nozzle is angularly oriented to directly impinge the calcium carbonate particles discharged from the transfer tube with the heated air volume. INDEPENDENT CLAIMS are also included for:    (1) a steam/methane reforming system operable to react a steam/methane volume to operably produce a hydrogen volume and a carbon dioxide volume, comprising calcium oxide particles entrained in the steam/methane volume operable to react with the carbon dioxide volume to operably form calcium carbonate particles; a calciner having an inlet, and operable to reform the calcium carbonate particles into the calcium oxide particles; a calciner injector (34) disposed upstream of the calciner operable to discharge the calcium carbonate particles into the calciner; a volume of hot vitiated air injectable into the calciner injector; and flow nozzles connectable to the calciner injector operable to direct the volume of hot vitiated air to directly impinge with the calcium carbonate particles discharged from the calciner injector at the inlet to the calciner; and    (2) a method of using a calciner injector to inject calcium carbonate particles into a calciner for regeneration of the calcium carbonate particles into calcium oxide particles, comprising reacting the calcium oxide particles with a carbon dioxide volume to operably form the calcium carbonate particles; connecting the calciner injector to the calciner; transferring the calcium carbonate particles through feed tube(s) (32) partially housed within the calciner injector into the calciner; flowing a volume of heated vitiated air through the calciner injector; and redirecting the volume of heated vitiated air into the calcium carbonate particles at an inlet to the calciner.
