<p>The invention relates to a method for the allothermal gasification of solid, carbon-containing gasification fuels, in which the gasification fuel is dried in a dryer (30) and is subsequently gasified in a fluidised bed vapour gasifier (10), wherein the heat required for the allothermal gasification is supplied to the fluidised bed vapour gasifier (10) by means of inert heat transfer media, in particular finely divided solids, which are circulated through the fluidised bed vapour gasifier (10) and through a separate fluidised bed combustion (20). In order to generate less problematic waste during such a method and yet achieve a good yield of hydrogen-rich product gas, according to the invention the gasification fuel is dried in the dryer (30) in a vapour atmosphere and flue gas-free and water vapour-containing drying vapours that develop and are generated during drying are fed to the fluidised bed vapour gasifier (10) as a fluidising medium and as a reactant.</p> |
