Definitions

  • the invention is directed to a process for the gasification of a biomass in a fluidized bed, wherein the biomass first pre-dried and supplied to the fluidized bed gasifier, then the raw gas from the gasifier a recycle cyclone and subsequently applied at least one raw gas cooler.
  • a problem of the known technologies for the gasification of biomass in a fluidized bed is that the C-conversion is not sufficient or could be significantly improved and that the deposition of noxious gases, such as H 2 S or HCl, makes additional equipment parts necessary.
  • this object is achieved according to the invention in that the dusts occurring in a downstream of the raw gas cooler hot gas filter dusts are returned to the entry system of biomass. As a result of this recycling, a significant improvement in the C conversion in the gasification of biomass is achieved.
  • it may be provided to remove dust from a dust silo connected downstream of the warm gas filter.
  • sorbents are supplied, it being possible to provide in a further embodiment that the sorbents are metered from a silo by means of a lock.
  • the sorbents are separated into the warm gas filter separated from the raw gas together with the dust in the circuit.
  • the invention also provides that additives in a weighing container or by metering in a screw conveyor supplied as additives, for example, iron ore, calcium carbonate, calcium oxide, calcium hydroxide, dolomite od. Like. be used.
  • the plant generally designated 1 for the gasification of a biomass in a fluidized bed is essentially formed by the plant elements described below:
  • a wood drying and storage is denoted by 2, wherein via a lock, e.g. a rotary valve 3, the material to be processed first a weighing container 4, then an entry lock 5 and finally a feed container 6 is supplied.
  • a lock e.g. a rotary valve 3
  • the material to be processed first a weighing container 4, then an entry lock 5 and finally a feed container 6 is supplied.
  • the material from the storage container 6 is then again via a rotary valve 7 and at least one screw 8, in the example shown two screws 8 are shown, the carburetor 9 fed and gasified there.
  • the gas is fed to a recycling cyclone 10 and from there finally fed to a raw gas cooler 11 and via a hot gas filter 12 for further use.
  • the dust silo is denoted by 13.
  • Essential is the dust return line, generally designated 14, through which the dust from the hot gas filter can be returned to the gasifier by gravity, the product being conveyed by way of cell Radschleusen 15 and, for example, a further screw 16 is guided.

Abstract

Procédé de gazéification de biomasse dans un lit fluidisé selon lequel la biomasse est d'abord préséchée et introduite dans un gazéificateur à lit fluidisé, le gaz brut est ensuite évacué du gazéificateur et amené à agir sur un cyclone de recyclage et ensuite sur au moins un refroidisseur de gaz brut. L'objet de la présente invention est d'améliorer le rendement d'un tel processus et de réduire les frais d'investissement. A cet effet, les poussières s'accumulant dans un filtre à gaz chauds monté en aval du refroidisseur de gaz brut sont renvoyées dans le système d'introduction de la biomasse.
