Abstract
A fluidized bed reactor arrangement includes a bottom portion and a roof portion. A reaction chamber is defined by at least one side wall extending between the bottom portion and the roof portion. The at least one side wall includes a vertically extending portion having a lower end and a lower portion, which lower portion is inclined in such a manner that a cross section of the reaction chamber decreases towards the bottom portion. A heat exchange chamber, outside of the reaction chamber, is at the lower portion of the at least one side wall. The lower portion of the at least one side wall forms a partition wall between the heat exchange chamber and the reaction chamber. The heat exchange chamber extends from the partition wall to a rear wall of the heat exchange chamber.

A fluidized bed reactor arrangement comprising:
- a bottom portion;
- a roof portion;
- a reaction chamber defined by at least one side wall extending between the bottom portion and the roof portion, the at least one side wall comprising a vertically extending portion having a lower end and a lower portion, which lower portion is inclined in such a manner that a cross section of the reaction chamber decreases towards the bottom portion;
- and
- a heat exchange chamber, outside of the reaction chamber, at the lower portion of the at least one side wall, the lower portion of the at least one side wall forming a partition wall between the heat exchange chamber and the reaction chamber, the heat exchange chamber extending from the partition wall to a rear wall of the heat exchange chamber,
- wherein the rear wall of the heat exchange chamber comprises (i) a lower portion extending to the other side, than the partition wall, of a plane extending via the vertically extending portion of the at least one side wall and (ii) an upper portion, wherein a plane extending via the upper portion of the rear wall joins for a predetermined distance from a connection of the heat exchange chamber and the lower end of the vertically extending portion of the at least one side wall with the plane extending via the vertically extending portion of the at least one side wall.
