1. A fluidized bed reactor having a top, said fluidized bed reactor comprising:
a fluidized bed; tubed membrane walls cooled by a coolant fluid, said tubed membrane walls defining side walls of a combustion chamber having a bottom; at least one partition wall extending between parallel tubed membrane walls to divide the combustion chamber; and tubed extension panels extending within the combustion chamber through which flows a coolant fluid by single pass forced circulation, said extension panels are paired to form a double wall extension, the tubed extension panels including tubes and membranes each tube is contacted by a membrane, wherein the tubed membrane walls and the tubed extension panels are exposed to heated material of the fluidized bed on only one side, wherein said extension panels are arranged on and extend from the at least one partition wall to a point within an inner area of the combustion chamber between the partition wall and one of the parallel tubed membrane walls, and wherein the at least one partition wall is a double wall partition formed of tubed panels paired together. |
