A fluidized bed boiler has a heat exchanger with a front wall, a rear wall opposite to the front wall, and two side walls, formed as water tube panels. An inlet opening in a first section of an upper portion of the heat exchanger introduces hot particles from the fluidized bed boiler to the heat exchanger. Heat exchange surfaces for recovering heat from the particles and an outlet opening are arranged in a second section of the upper portion for returning cooled particles as an overflow from the heat exchanger back to the boiler. The heat exchanger further includes a partition wall between the first and the second sections of the upper portion of the heat exchanger. The partition wall extends from the front wall to a center section of the heat exchanger, and is formed by bending water tubes from at least one side wall of the heat exchanger. |
