ABSTRACT The invention concerns a fluidized bed process for the gasification and combustion of fuels in differently fluidized zones separate from one another , the fuel being charged into a drying and pyrolysis zone with lower fluidization and solids transport downwards, the solids conveyed downwards being conveyed from the lower part of the drying and pyrolysis zone to the lower part of a combustion zone with higher fluidization and solids transport upwards and recirculating, after passing the combustion zone, from the upper zone thereof to the drying and pyrolysis zone, comprising that the solids are conveyed upwards in a combustion zone operated as a fast or turbulent fluidized bed beyond the bed height in the drying and pyrolysis zone and are subsequently forcibly deflected so that the solids drop down on the surface of the bed in the drying and pyrolysis zone as a shower of particles , that the fuel is metered into the shower of particles and that the gases emerging from the combustion zone are passed under use of their flowing pulse, optionally together with the gases rising from the drying and pyrolysis zone, into a turbulence zone in which a post-combustion is carried out, and further an apparatus for carrying out said process, said apparatus being a fluidized bed reactor with bed material circulating between two differently fluidized zones which are connected to one another in their lower parts, said reactor having a guidance means for the faster combustion zone extending in height beyond the slower bed material circulating one and on whose upper end a solids deflection means for generating a shower of bed material dropping down on the slower zone is provided, comprising that a fuel feed is provided in the dropping area of the shower of bed material.
