Fluidized Bed Reactor Arrangement

A fluidized bed reactor arrangement comprising:

• a reaction chamber;
• a bottom portion;
• a roof portion;
• at least one side wall vertically extending between the bottom portion and the roof portion, the side wall being arranged to be inclined at a lower portion in such a manner that a cross section of the reaction chamber decreases towards the bottom portion;
• and
• a heat exchange chamber at the inclined area of the at least one side wall outside of the reaction chamber, and which side wall, extending between the bottom portion and the roof portion and being arranged to be inclined at the lower portion thereof, forms a partition wall between the heat exchange chamber and the reaction chamber, and in which the heat exchange chamber extends from the partition wall to the other side of a plane extending via the at least one side wall,
• wherein the rear wall of the heat exchange chamber is connected to the side wall of the reaction chamber from the upper portion of the rear wall at a connection area in such a manner that the direction thereof aligns with the direction of the side wall at least at the connection.
