<p>Dried fuel is at least partly combusted, gasified or carbonized in the presence of cooled solid residue in a reactor. Hot solid residue, which is at temperatures in the range from 500 DEG to 1200 DEG C., is withdrawn from the reactor and is mixed with water-containing fuel in the receiving region of a mechanical mixer, without a supply of fluidizing gas. The mixture is transported with further mixing from the receiving region of the mixer through a mixing section of 1 to 10 meters to an outlet. A fuel-containing, substantially water-free mixture at a temperature in the range from above 100 DEG C. to 150 DEG C. is fed from the outlet of the mixer to the reactor. A mixer which comprises two intermeshing shafts, which rotate in the same sense, may be employed in the process.</p> |
