A fluidized bed system (10) which includes a housing (12) and a floor (14) comprising a plurality of generally parallel tubes (32) joined by fins (34) intermediate adjacent tubes (32). A plurality of nozzle assemblies (30, 50) extend generally vertically in mutually parallel relationship from the floor (14). Each of the nozzle assemblies (30, 50) includes a generally cylindrical body (36) having a centerline disposed in generally perpendicular relationship to the floor (14) and each of the bodies (36) includes a plurality of heads (38) extending generally radially therefrom at an axial extremity thereof remote from the floor (14). In some embodiments of the invention each of the heads (38) are uniformly spaced around the circumferential extent of each of the bodies (36) and each of the heads (38) is generally cylindrical and has a centerline. Each of the centerlines of the heads (38) may be disposed at an angle with respect to a horizontal plan and the angle may be approximately twenty degrees. In some forms of the invention some of the nozzle assemblies (30, 50) each have four heads (38) and some of the nozzle assemblies (30, 50) have two heads (38). In other embodiments all of the nozzle assemblies (30, 50) have two heads (38). In other embodiments all of the nozzle assemblies (30, 50) have four heads (38).

Un système à lit fluidisé (10) comprend un corps (12) et un fond (14) comportant une pluralité de tubes généralement parallèles (32) réunis par des pattes (34) placées entre les tubes adjacents (32). Une pluralité d'ensembles ajutages (30, 50) s'étendent généralement verticalement et parallèlement au fond (14). Chaque ensemble ajutage (30, 50) comporte un corps généralement cylindrique (36) dont l'axe est généralement perpendiculaire au fond (14) et chaque corps (36) est pourvu d'une pluralité de têtes (38) s'étendant généralement radialement à partir de celui-ci au niveau d'une extrémité axiale éloignée du fond (14). Dans certains modes de réalisation de l'invention, toutes les têtes (38) sont uniformément réparties sur la surface circonférentielle de chaque corps (36), et sont généralement cylindriques et pourvues d'un axe. Chaque axe des têtes (38) peut se situer au niveau d'un angle par rapport à un plan horizontal et l'angle peut être approximativement de vingt degrés. Dans certaines structures de l'invention, certains ensembles ajutages (30, 50) possèdent chacun quatre têtes (38) et d'autres deux têtes (38). Dans d'autres modes de réalisation, tous les ensembles ajutages (30, 50) ont deux têtes (38), et dans d'autres modes de réalisation, quatre têtes (38).
