Process for gasifying combustible material comprises pyrolyzing in a first reactor at a first temperature; and feeding the gaseous pyrolysis products from the first reactor to a second reactor for reaction at a second higher temperature to partially oxidize the products by introducing oxygen. The pyrolysis is carried out in the first reactor with the exclusion of oxygen and energy is introduced to the first reactor by introducing a part of the gaseous reaction products of the second reactor. An independent claim is also included for an apparatus for gasifying combustible material. Preferred Features: The first temperature is below the ash melting point, preferably between 600 and 900, especially 800[deg] C, and the second temperature lies in the region of the decomposition of the long chain hydrocarbons, preferably above 1000, especially 1250[deg] C. Pyrolysis in the first reactor and/or reaction in the second reactor are carried out in a fluidized layer, especially using dolomite as the fluidized bed layer material.
