Abstract

Method and device for gasification of solid carbon- containing material in a circulating fluidized bed reactor. Particles are separated from the produced gases in at least two stages so that in the first stage mostly the coarser so-called circulating particles are separated, which are returned to the reactor, and in the second stage, fine carbon-containing dust which agglomerated at elevated temperature is separated and the obtained larger particles returned to the reactor in the return line together with the circulating particles. One advantageously prevents the agglomerating particles from being attached to the walls of the tube by leading the hot dust particles to the center of the tube and the circulating particles to the walls of the tube.
