  • Patent number: 11806683
    Abstract: A fluidizing nozzle for introducing fluid into a fluidized bed reactor and a fluidized bed reactor. The fluidizing nozzle includes a nozzle tube limiting at least a part of a feed channel in which fluid is configured to flow, at least one fluid discharge opening arranged near a downstream end of the nozzle tube, and a pot-like hood, which sealingly closes the nozzle tube with a hood cover of the pot-like hood at the downstream end of the nozzle tube at which said at least one fluid discharge opening is provided. The feed channel is provided with a flow restriction element defining at least one flow restriction feed channel upstream of said at least one fluid discharge opening.

  • Publication number: 20220411310
    Abstract: Producing a molded body made of opaque quartz glass includes providing SiO2 grains obtained by comminuting quartz glass having a purity of at least 99.9 wt % SiO2, forming a slurry containing a suspension liquid and the SiO2 grains and which has a total solids content, wet grinding the SiO2 grains in the slurry so as to form ground SiO2 grain particles, forming a porous green body from the slurry, and sintering the porous green body. To provide a low cost quartz glass, the wet grinding of the SiO2 grains takes place at least temporarily in the presence of SiO2 nanoparticles, the proportion of which in the total solids content of the slurry is in the range of 0.1 wt % to 10 wt %, and the slurry has a solids content in the range of 76 to 80 wt % after addition of the SiO2 nanoparticles and after the wet grinding.

  • Patent number: 8337801
    Abstract: A process for producing calcine products includes dead roasting a metal sulfide concentrate having a low sulfur content. The concentrate is roasted in a circulating fluidized bed at a temperature of about 950 to 1050° C. A waste gas of the fluidized bed is passed through at least one of a recuperator and a Venturi drier so as to respectively provide at least one of a preheating of at least a portion of air fluidizing the fluidized bed and a drying of at least a portion of the concentrate to be roasted. The calcine product obtained in the fluidized bed with a sulfur content of less than 1 wt-% is provided for further processing.
