Device For Producing Fuel Gas

Abstract

The present invention relates to a device for producing fuel gases from carbon-containing material, in particular a wood gas generator, comprising a degassing zone and an oxidation zone, as well as a method for producing a fuel gas having a high calorific value by simple means, for which the degassing zone consists of a degassing chamber containing a molten metal, preferably tin, wherein the degassing chamber is designed to operate with air excluded.

1 . A device for producing fuel gases from carbon-containing material, in particular a wood gas generator, comprising a degassing zone and an oxidation zone, characterised in that the degassing zone consists of a degassing chamber containing a molten metal, preferably tin, wherein the degassing chamber is designed to operate with air excluded and wherein a conveying device is provided for conveying the carbon-containing material through the metal bath. 
   
   
       2 . The device according to  claim 1 , characterised in that the degassing chamber contains metal chips and/or catalysts, preferably in the metal bath. 
   
   
       3 . The device according to  claim 1 , characterised in that a conveyor screw which penetrates the degassing chamber is provided, said conveyor screw preferably being designed as thermally insulated in its regions located outside the degassing chamber. 
   
   
       4 . The device according to  claim 1 , characterised in that the conveyor screw is designed as sieve-like in the area of the metal bath. 
   
   
       5 . The device according to  claim 1 , characterised in that the oxidation zone consists of an oxidation chamber which at least partially encloses the degassing chamber. 
   
   
       6 . The device according to  claim 1 , characterised in that this comprises a fuel gas purification system. 
   
   
       7 . A method for producing fuel gases from carbon-containing material, in particular wood gas, preferably using a device according to  claim 1  comprising the steps of pre-drying the combustible material, degassing the combustible material in a metal bath whilst excluding air, oxidising the degassed combustible material and purifying the fuel gas, preferably thermally.
