Abstract
An apparatus for the cooling of hot fluidized solid particles. The apparatus comprises in combination: (a) a vertically oriented combustion chamber; (b) a disengagement chamber above and connected to the combustion chamber; (c) a collection section at the bottom of the disengagement chamber; (d) a vertically oriented shell and tube heat exchanger with the shell closed at the bottom and the top of the shell in sealed communication with the disengagement chamber such that the particles can circulate to and from the shell and disengagement chamber; (e) a fluidizing gas inlet in the bottom of the shell such that fluidizing gas can enter the shell and continuously backmix the particles; (f) an inlet and outlet to the tubes of the heat exchanger such that a cooling fluid can flow through the tubes; and (g) a control valve in the fluidizing gas inlet with a control system which controls the quantity of cooling fluid removed from the tubes by controlling the amount of fluidizing gas to the heat exchanger which regulates the duty of the heat exchanger.
