Assembly and a method of installing an assembly of a particle separator module and a heat exchange chamber module, and a circulating fluidized bed boiler with such an assembly

A circulating fluidized bed boiler comprising:

• an assembly of a particle separator module and a heat exchange chamber module connectable in a vertical position to the circulating fluidized bed boiler, the assembly comprising:
• (A) the heat exchange chamber module that comprises a top surface;
• and
• (B) the particle separator module, which is top-supportable, and comprises a cylindrical upper portion with an outer wall having a tube wall construction, a conical lower portion, and a lower end that is sealably connectable to the top surface of the heat exchange chamber module so as to convey particles from the particle separator module to the heat exchange chamber module when in use in connection with the circulating fluidized bed boiler, the particle separator module further comprising:
• (a) 2N vertically aligned steam tubes, wherein N is an integer greater than one, each of the vertically aligned steam tubes being attached to the cylindrical upper portion and extending downwards to a predetermined level located between the cylindrical upper portion and the lower end;
• and
• (b) N first beams, wherein each of the 2N vertically aligned steam tubes is attached to one of the N first beams so that each of the N first beams is suspended to hang in a horizontal position at the predetermined level by two adjacent steam tubes of the 2N vertically aligned steam tubes,
• wherein the heat exchange chamber module is provided with N second beams attached in a horizontal position to the top surface of the heat exchange chamber module, and the heat exchange chamber module is arranged to be suspended from the particle separator module by having each of the N second beams suspended by two adjacent beams of the N first beams.
