TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Method: The carbonaceous mass is converted in at least one gasification unit (5) into a combustible gas, and the coke is removed from the gasification unit. The carbonaceous mass is converted into combustible gas in at least two gasification units, and the coke is removed from the last gasification unit. A part of coke is remaining during periods of lower heat consumption to complete gasification in the process, which is required to produce electrical energy. At least one gasification process is carried out at an air ratio of about 0.2. The pyrolysis residue arising during the gasification process, preferably ash is removed in the process and the extracted pyrolysis residue, the extracted coke and dried biomass are processed to calorific value storage, preferably pellets. The generated thermal energy is used for drying the biomass. The removed, energetically processed intermediate product is recycled during periods of higher heat consumption. The removed, energetically processed intermediate product is processed with the addition of other substances into calorific value storage and the calorific value storage is utilized during periods of higher heat consumption again. The pyrolysis residue removed the gasification process, preferably ash and dry biomass, are used as other substances. The calorific value storage contains pyrolysis residue removed the gasification process, preferably ash and dry biomass.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: At least one gasification unit generating thermal energy is provided for converting the carbonaceous mass into combustible gas and at least one apparatus for generating electrical energy from a combustible gas, and at least one material outlet is provided for coke from at least one gasification unit, which opens into the intermediate bearing. At least two gasification units are provided and the material outlet is arranged in the region of the last gasification unit, preferably starting from the last gasification unit. The plant has: a device for processing the removed, energetically processed intermediate product into pellets; and a dryer (2) for carbonaceous mass, preferably biomass, into which a line opens for hot exhaust air from at least one device for generating thermal energy.
