Abstract
A grid construction for a fluidized bed reactor, the reactor including a reaction chamber defined by substantially vertical walls, in which a fluidized bed of solid particles is maintained, and a windbox under the reaction chamber, in a lower portion of the reactor. The grid construction is positioned between the reaction chamber and the windbox and includes (a) multiple continuous nozzle lines for distributing fluidizing gas from the windbox into the reaction chamber, for suspending the fluidized bed in the reaction chamber, and (b) continuous trenches between the nozzle lines. The nozzle lines include multiple gas outlets, having a main gas flow direction, at side faces of said nozzle lines, for directing fluidizing gas jets towards an adjacent trench.
