<p>The invention relates to a method for the thermochemical conversion of a fuel, comprising the following steps: a) provision of a fluidised-bed reactor with a central first combustion zone ( 1 ) and a second combustion zone ( 7 ) that is separated from the first by flow conduction means ( 2, 15 ), the first combustion zone ( 1 ) being provided with a supply opening ( 16 ) for supplying fuel and a unit ( 3 ), which lies opposite the supply opening ( 16 ) on the floor (B) of the fluidised bed reactor, for deviating a stream of fuel into the second combustion zone ( 7 ); b) feeding of fuel through the supply opening ( 16 ), so that a stream of fuel forms that is directed towards the floor (B); c) deviation of the stream of fuel on the floor (B) into the second combustion zone ( 7 ), so that the stream of fuel is guided in an essentially opposite direction; and d) additional deviation of the stream of fuel in the vicinity of the supply opening ( 16 ), causing the stream of fuel to be returned to the first combustion zone.</p> |
