DETAILED DESCRIPTION - The device for producing synthesis gas from biomass by flow gasification, comprises a treatment plant (1) for the biomass, which comprises a coarse-grinding device (2) for the biomass that is connected at downstream over a first lock (3) with a carbonization equipment (4) for the hydrothermal production of carbonization coal of the biomass, where the carbonization equipment comprises a preheating device (5), a carbonation reactor, which is arranged downstream to the preheating device and connected over a second lock with a solid-liquid-separator device for providing a fuel, a transfer device for transferring the fuel and an entrained flow gasification plant. The transfer device provides a coupling of the treatment plant with the entrained flow gasification plant. The treatment plant comprises a drying device downstream to the firm-liquid-separator device for drying the fuel, which is arranged downstream to a shredding device that provides a crushing of the fuel into a pulverized fuel with particle size of 55-500 mu m. The biomass comprises wood, waste wood, green waste, grass, agricultural products and waste products, straw and/or residues from a biomass processing. The shredding device is connected with a supply pipe for the resource such as for grinding- and/or anti-caking agents. The gasification plant comprises a fuel supply, which is coupled with the transfer device and is connected at downstream over a third lock with a conveying system for the fuel, which flows itself into the gasification device from which a discharge line extends itself for the slag, and a product line extends itself for the synthesis gas. The gasification device comprises a burner in which a supply line flows for a gasification agent and is connected with an entrained flow gasification reactor, which comprises a reaction chamber equipped with a refractory lining and/or a cooling device and a cooling chamber downstream to the reaction chamber, where the cooling chamber is connected over a recovery device with the product line. The cooling chamber is a quenching chamber with supply lines for quenching water and/or quenching gas, comprises a device for indirect gas cooling by means of a radiation- and/or convection cooler or a combination of the quenching chamber and device for indirect gas cooling. The entrained flow gasification reactor comprises a slag swamp downstream to the reaction chamber, and covers itself over a fourth lock of the discharge line. The conveying system is a pneumatic dense phase conveying system, which comprises a delivery gas line, or is a pump conveying system. The fuel is provided in the form of a hydraulic recoverable fuel mash, which comprises the fuel and combustible liquid, where the fuel mash is provided into a maisch device, which is arranged downstream to the pump conveying system into the entrained flow gasification plant or the treatment plant and comprises a feeding device for the combustible liquid. An INDEPENDENT CLAIM is included for a method for producing synthesis gas from biomass.
