摘要： A fluid bed reactor is provided having a grid baffle structure to provide increased theoretical stages within the reactor to enable the reactor to be used for time/temperature dependent reactions requiring a number of mixing stages and/or an increased particle residence time. The preferred baffle structure comprises a plurality of staggered first and second vertical members extending partly across the reactor from opposed sides of the reactor which form a path for the feed to travel therethrough from the inlet to the outlet of the reactor with the vertical members having vertical cross-members, preferably shorter than the vertical members, extending completely between adjacent vertical members and/or partly in the space between the members to form reaction stage sections whereby feed entering the reactor moves in a serpentine path and/or a sequential underflow and/or overflow path through the reaction stage sections of the baffle from the inlet of the reactor to the reactor outlet.

摘要： A method and system for introducing combustion gases to the upper portion of the dense phase or transition portion of a circulating fluidized bed reactor. The combustion gases are produced in a burner external to the dense phase portion of the reactor wherein the burner receives a mixture of liquid or gaseous fuel and air so as to initiate and maintain combustion within the burner. The combustion gases are then quenched prior to entering the dense phase portion of the reactor so as to reduce the temperature of the combustion gases thereby preventing overheating or sintering of the particulate and significant oxidation reduction in the dense phase portion of the reactor.

摘要： Apparatus is provided for withdrawing a stream of relatively static bed material from an operating fluidized bed reactor and gravity feeding it through a conduit to an exterior classifying chamber into which a downward flow of air is introduced. The airflow is turned in the classifier to move in an upward direction countercurrent to the flow of bed material. The velocity of the air is such that coarse bed material passes downwardly through the airflow and accumulates in the classifying chamber, while the fines are entrained in the upwardly moving airflow and both air and fines are introduced into the fluidized bed reactor.

摘要： A method for dehydrating alunite ore prior to further processing to recover metals therefrom, comprising exposing the ore in particulate form to burning coal as the heat supply in a fluidized bed fluidized with an oxygen containing gas. The invention is illustrated by the removal of water from alunite ore prior to further processing the ore to recover aluminum.
