Abstract
A cyclone for separating a mixture of gas and solid particles by centrifuging into a fraction that is enriched in particles and a gaseous fraction that is depleted in particles, the cyclone comprising a cylindrical vessel into which a duct for injecting the mixture of gas and solid particles opens out tangentially, an axial duct for removing the gaseous fraction, means for removing the fraction that is enriched in particles, which means are situated in the bottom portion of the cylindrical vessel, gas injection means serving to fluidize the solid particle enriched fraction as a dense bed, and heat exchanger means for exchanging heat between the dense fluidized bed that is formed and a fluid to be vaporized and/or reheated, together with means for adjusting the level of the dense bed.
