1. A fluidizing nozzle for introducing fluid such as gas into a fluidized bed reactor, comprising:
a nozzle tube limiting at least a part of a feed channel in which fluid is configured to flow,
at least one fluid discharge opening arranged near a downstream end of the nozzle tube for discharging fluid from the nozzle tube to the surroundings, and
a pot-like hood, which sealingly closes the nozzle tube with a hood cover of the pot-like hood at the downstream end of the nozzle tube at which said at least one fluid discharge opening is provided, wherein the pot-like hood includes a hood apron connected with the hood cover, which hood apron surrounding a part of the nozzle tube by forming an annular cap extending from the downstream end of the nozzle tube at which said at least one fluid discharge opening is provided,
wherein the feed channel being provided with a flow restriction element defining at least one flow restriction feed channel upstream of said at least one fluid discharge opening,
wherein
the flow restriction element defining only one flow restriction feed channel, and by said only one flow restriction feed channel being in the form of a sonic nozzle.
