  • Method of combustion or gasification in a circulating fluidized bed
    Patent number: 6649135
    Abstract: A material containing combustible components is burned or gasified in a circulating fluidized bed comprising a turbulence chamber, a solids separator connected to the upper area of the turbulence chamber, a return line leading from the solids separator to the turbulence chamber and a cooling device for the indirect cooling of solids arriving from the solids separator. The cooling device comprises several fluidized beds through which the solids pass one after the other. The first fluidized bed, into which the hot solids arriving from the solids separator are introduced first, is situated in a dechlorinating chamber.

  • Fluidized bed combustion system with steam generation
    Patent number: 6481385
    Abstract: A solid fuel fluidized-bed steam generator in which a pair of combustion chambers straddle a heat-exchange chamber of rectangular configuration in a row and have one or more gas/solids separators connected to the combustion chambers at the tops thereof and lines which deliver gas from the separators to the heat-exchange chamber. The heat-exchange chamber has a plurality of heat-exchange elements for indirect heat exchange between hot gas and a cooling fluid, for example water, which is converted to steam.
