A method of heat transfer wherein a flat metal product having a broad face and a temperature upper to 400° C. is put in contact with a fluidized bed of solid particles, the solid particles having a direction of circulation (D), wherein the flat metal product is put in contact with the solid particles so that its broad face is parallel to the direction (D) of circulation of the solid particles and wherein a gas is injected so that the solid particles be in a bubbling regime, the solid particles capturing the heat released by the metal product and transferring the captured heat to a transfer medium. An associated device is also provided.

A method of heat recovery from bulk solids includes introducing the bulk solids into an inlet of a heat exchanger for indirect heat exchange with water as the bulk solids flow, by gravity, from the inlet to an outlet of the heat exchanger, pumping the water into subcritical heating heat transfer elements within the heat exchanger for indirect heat exchange with the bulk solids to heat the water and thereby provide heated, pressurized water, and flashing off steam from the heated, pressurized water.

A particle separator module and a heat exchange chamber module connectable to a circulating fluidized bed boiler. The particle separator module includes 2N vertically aligned steam tubes, N being an integer greater than one. Each of the vertically aligned steam tubes is attached to a boiler upper portion and extends downwards to a predetermined level. Each of the 2N vertically aligned steam tubes is attached to one of N first beams. 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. N second beams are attached in a horizontal position to the top surface of the heat exchange chamber module, which 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.
