A fluidizing gas nozzle head and a fluidized bed reactor with multiple fluidizing gas nozzle heads

摘要

A fluidizing gas nozzle head (24) suitable to be connected to a fluidizing gas feeding device of a fluidized bed reactor, the fluidizing gas nozzle head comprising an inlet channel (26) having a longitudinal axis, an inlet end (32) and a second end (36), the inlet end of the inlet channel being adapted to connect the inlet channel in vertical gas flow connection with the fluidizing gas feeding device, four outlet channels (46), each of the four outlet channels extending from a first end (44) to an outlet end (54), and a gas distribution space (42) having a bottom face (40) and a ceiling (48) opposite to the bottom face, wherein the second end of the inlet channel and the first ends of the four outlet channels are connected to direct gas flow connection with the gas distribution space, wherein each of the first ends of the four outlet channels has a central point, which central points define a rectangle with two long sides and two short sides having an aspect ratio of at least 2:1.
