NOVELTY - The device for the production of combustible gas mixture from split wood useful in a plant for the generation of electrical and/or heat energy, comprises a reactor (1) having a zone (10) for the oxidation of starting material and/or a zone (11) for the reduction of intermediate product of the oxidation, a bearing area arranged in vertical direction viewed under the reduction zone, a displacement element, a displacement drive formed as a motor shaft having a motor, a partially movable rust unit having a rust element for moving a part of the reduction zone, and outflow openings.    USE - Device for the production of combustible gas mixture from split wood useful in a plant for the generation of electrical and/or heat energy (claimed).    ADVANTAGE - The device ensures economical and safe production of combustible gas mixture with high quality, less consumption of split wood, high operational control facility and high environmental relevant requirements without formation of tar gas.    DETAILED DESCRIPTION - The device for the production of combustible gas mixture from split wood useful in a plant for the generation of electrical and/or heat energy, comprises a reactor (1) having a zone (10) for the oxidation of starting material and/or a zone (11) for the reduction of intermediate product of the oxidation, a bearing area arranged in vertical direction viewed under the reduction zone, a displacement element, a displacement drive formed as a motor shaft having a motor, a partially movable rust unit having a rust element for moving a part of the reduction zone, and outflow openings (60, 61) having air nozzles (16) for supplying oxygen and/or air, arranged in the area of the oxidation zone. Within the reduction and/or the oxidation zone, an interval is partially arranged to the bearing area along a circular displacement path of the displacement element for moving and/or mixing the reduction and/or oxidation zone. The longitudinal axis of the displacement element is partially aligned in vertical direction. A section of the displacement element is aligned acute or obtuse angle to the direction of the displacement path. The rust unit has a rust drive for shifting the rust elements along a rust displacement path. The displacement drive of the displacement element is same to the rust drive of the rust element. The displacement axis is same to the rotation axis of the rust element. The air nozzle has a horizontally directed air supply section for supplying oxidative agent to the outflow openings. The air nozzles have vertically directed nozzle opening sections having outflow opening arranged near to the horizontally directed air supply section. The outflow direction of the oxidation agent is horizontally directed diagonally to the longitudinal direction of the nozzle opening sections, which are arranged in radial direction of the reactor. The longitudinal direction of the air nozzle is aligned in radial direction. The number of air nozzles and/or nozzle opening sections is adapted to the diameter and/or cross sectional area of the oxidation and/or reduction zone. The air nozzles are intended with different number of outflow opening and/or nozzle opening sections. An INDEPENDENT CLAIM is included for a plant for the generation of electrical and/or heat energy.
