NOVELTY - The device has a fluidized bed reactor (C1) inserted into a fluidized bed heat transfer element (W1) that allows a certain heat input into the fluidized bed reactor without contact of flue gases with feedstock in the bed reactor, where the flue gases originate during heating the heat transfer element. A delivery device injects oxygen e.g. pure oxygen or atmospheric oxygen, in the bed reactor and makes release of heat in the bed reactor by partial oxidation of raw materials. A regulating device regulates the bed reactor at an operating point by changing added amount of oxygen.    USE - Device for generating hydrogen-rich synthesis gas from carbon-containing compounds i.e. biogenic materials.    ADVANTAGE - The device achieves the heat input by partial oxidation with the pure oxygen and the atmospheric oxygen, and device generates the synthesis gas in a simple and inexpensive manner. The device exhibits high reliability. The optimum mixing and reaction of oxygen with the carbon of the raw materials takes place at the operating temperatures from 780 to 830 degree Celsius due to the introduction of oxygen with the fluidizing steam, thus allowing direct release of the exothermic heat from the partial oxidation in the fluidized bed. The device forms a homogeneous temperature distribution in the fluidized bed due to the intense mixing in the fluidized bed, thus minimizing interfering reactions. The hydrogen atmosphere is formed with low partial pressures for heavy hydrocarbon compounds due to the implementation of the fluidizing steam at the operating temperatures of about 780 to 830 degree Celsius, thus reducing overall tar formation in the device. The device destructs possibility of oxygen injection in the expansion space tars, and increases the carbon conversion.
