Heat exchanger with dense fluidized bed combined with a reactor with circulating fluidized bed

摘要

The fluidised bed exchanger has a casing (1) whose longitudinal vertical walls (1A,1B) are formed from tubes which transport a fluid. The tubes are divided lengthways into chambers separated from each other by a low wall (10) of liquid circulating tubes. The longitudinal walls comprise horizontal tubes (11A,11B,12A,12B) and the low wall extends from the inner wall of the casing to a height less than that of the casing. This low wall is made up of superposed, transversal extensions of the tubes (11A,11B) for each of the faces of the longitudinal vertical walls, in the form of hair clips, perpendicular to the tubes and extending upto the opposite longitudinal face.
