APPARATUS AND METHOD FOR GENERATING FUEL GAS FROM A SOLID COMBUSTIBLE

The invention relates to a method and an apparatus for generating fuel gas from a solid material in a shaft gasifier, and comprises a gasification zone, into which the solid material can be filled, and an oxidation zone designed to oxidize the generated gas connected to the gasifier zone so that the gases generated in the gasifier zone run to the oxidation zone. A first air supply device and a second air supply device downstream of the first air supply in the processing direction of the solid material supply air into the gasification zone. A measurement unit samples the raw gas that is generated in the oxidation zone or of the flammable product gas. A control unit, which is coupled with the measurement unit by means of signal technology, transmits a test signal and controls the air supplied by the second air supply device via the test signal.
