Method and a device for controlling the temperature of a reaction carried out within a vessel in a fluidized bed containing solid particles which can be entrained with the smoke and then recovered in a separating device and recycled into the fluidized bed after passage through a heat exchanger where they yield up their heat. The flow of particles separated from the smoke is divided into two parts, a hot part recycled directly into the fluidized bed and a cool part constituted by particles taken up at the outlet of the separating device and passed into the heat exchanger to constitute a reserve of cold material which can be mixed with the hot part before reinjection into the fluidized bed, the relative flow rates of the hot particles and of the cold particles being regulated so as to control the flow-rate and the average temperature of the flow of particles recycled into the fluidized bed for maintaining at the desired level the reaction temperature in the midst of the latter.
Method for controlling the temperature of a reaction conducted inside a vessel, in a fluidized bed containing solid particles which can be entrained with smoke and then recovered in a separating device and recycled into said fluidized bed after passage into a heat exchanger where they yield up their heat, said method comprising the steps of
Control device for the temperature of a reaction carried out in a fluidized bed within a vertical vessel in which is arranged a fluidized bed of material to be treated comprising heavy particles and fine particles, said vessel being provided at its lower part with means for the injection of a fluid at a speed such that a large proportion of said fine particles is entrained toward a chimney for the removal of gases located at an upper part of said vessel and discharging into a recovery chamber for said fine particles entrained with the gases, connected to a base of said fluidization vessel through a circuit for recycling said recovered fine particles into said fluidized bed, said device comprising
