Abstract

A fluidizing gas nozzle head suitable to be connected to a fluidizing gas feeding device of a fluidized bed reactor. The fluidizing gas nozzle head includes an inlet channel having a longitudinal axis, an inlet end, and a second end, 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, each of the four outlet channels extending from a first end to an outlet end, and a gas distribution space having a bottom face and a ceiling opposite to the bottom face. 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. 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.

Dependent claims

A fluidizing gas nozzle head suitable to be connected to a fluidizing gas feeding device of a fluidized bed reactor, the fluidizing gas nozzle head comprising:

(A) an inlet channel having a longitudinal axis, an inlet end, and a second end, 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;
(B) four outlet channels, each of the four outlet channels extending from a first end to an outlet end;
(C) a gas distribution space having a bottom face and a ceiling opposite to the bottom face;
and
(D) a partition wall connected to the ceiling and arranged in a symmetry plane of the gas distribution space,
wherein the second end of the inlet channel and the first ends of the four outlet channels are in direct gas flow connection within the gas distribution space, and
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, and the gas distribution space being divided by a division wall into two identical halves so that two outlet channels are on the same side of the division wall.
