Title
(EN) A COMBUSTOR AIR BAR GRID FOR USE WITHIN A FLUIDIZED BED REACTOR, AND A FLUIDIZED BED REACTOR
(FR) GRILLE DE BARRE D'AIR DE CHAMBRE DE COMBUSTION DESTINÉE À ÊTRE UTILISÉE DANS UN RÉACTEUR À LIT FLUIDISÉ, ET RÉACTEUR À LIT FLUIDISÉ
Abstract
(EN)
A combustor air bar grid (1) for use within a fluidized bed 5 reactor (12) comprises- at least two main air collector bars (2) in fluid communication with a source of fluidizing gas; - a plurality of primary air bars (3) that are transversal to said main air collector bars (2) and arranged on said 0 at least two main air collector bars (2) such that the main air collector bars (2) support them, and in fluid communication to at least two of said main air collector bars (2), the main air collector bars (2) and the primary air bars (3) defining ash removal openings in the air bar 5 grid (1); and- a plurality of fluidizing nozzles (4) arranged to each of the primary air bars (3) for fluidizing the bed reactor (12).The patent application also contains an independent claim for a 0 fluidized bed reactor.
