摘要： A method and an apparatus for producing generator gas and activated carbon from solid fuels. A first gasification stage is supplied with fuel by an underfeed charging system and preheated air, the air and fuel being supplied in the same direction. In a second gasification stage and accompanied by the supply of secondary air, an intermediate gasification takes place. Finally, in a third gasification stage, the gas is reacted with glowing coke or charcoal, and the heat of the exiting gas is used for heating the air. The fuel centrally entering the first gasification stage is led from the inside to the outside and then upwards. Part of the entering fuel is precombusted in a precombustion chamber linked with the supply of the preheated air for reducing the oxygen content of the preheated air. In the intermediate gasification stage, the gas with the admixed air is passed through a Venturi nozzle or tube with a diffuser. The flue coal entrained from the first gasification stage is at least partly returned to the throat of the Venturi tube. The return is assisted both by vacuum in the Venturi tube and mechanically.

摘要： A three stage process for producing producer gas from biomass or other carbonizable waste products using a double gasifier is described. A reactor for the three stage process comprising a primary, an intermediate and secondary gasifier is also described. The primary gasifier utilizes a vertically adjustable fill level sieve and a discharge mechanism for the combustion residues. The primary fuel and the preheated primary air are supplied to the primary gasifier via the reactor base. The secondary gasifier, a coke producer is connected to the primary gasifier downstream. The intermediate gasifier, a fluw flow gas converter, is supplied with secondary air. The low temperature carbonized gas from the primary gasifier, as well as the carbon particles leaving the primary gasifier are introduced into the secondary gasifier through a radially symmetrical ring nozzle to provide a long residence time under reducing conditions. The reactor is also optionally provided with one other gas, comprising at least in part the product, producer gas, introduced via a bypass arrangement.

摘要： A process for the separation of solid and/or liquid particles from gases or solids from liquids, as well as for the separation of gases or liquids with different densities is proposed, in which a Venturi tube is used. The gas and/or liquid mixture is introduced inwards in radially symmetrical manner from the outside through the slot of an annular nozzle at a high flow velocity which, in the case of gases, extends up to the velocity of sound. The gas is subject to the action of a high centrifugal acceleration in the slot, which has a radius of curvature of approximately 1 to 100 mm.
