Process for the production of electrical energy and/or heating and

A method of generating a low-tar generator gas includes contacting the hot tar-containing generator gas in a contact zone with ballast bodies to cool the generator gas and capture tar and dust on the exposed surfaces of the ballast bodies, and admixing the thus heated ballast bodies to the wet solid fuel to be gasified to dry and pre-heat such fuel in preparation for the actual gasification which is performed in two separate gasification zones which are arranged one above the other by reacting the solid fuel with an oxygen-containing gasification medium that is introduced from above into the upper one, and from below into the lower one, of the gasification zones with attendant formation of two conflagration fronts in the gasification zones. The generator gas which is thus generated in the two gasification zones is discharged through a common discharge conduit which has the contact zone incorporated therein. An arrangement for performing this method includes a contact apparatus which bounds the contact zone, is incorporated in the discharge conduit and contains a bed of the ballast bodies, the bed being replenished by ballast bodies which have been separated from ashes after they have been discharged from the lower one of the gasification zones.
