Abstract:
Apparatus for exchanging heat between a gas and a pulverulent matter, comprising:a chamber having a substantially horizontal floor, a ceiling, a front wall, a back wall, and two side walls; means for introducing said pulverulent matter into said chamber; means for maintaining within said chamber a volume of said powder that is significantly smaller than the volume of said chamber; means for imparting a substantially vertical vibration to said chamber at a vibrational intensity sufficient to cause said matter to enter a coherent-condensed vibrated-bed state, thereby creating a vibrated bed that occupies a lower part of said chamber and a space that extends from the surface of said bed to said ceiling; means for withdrawing matter from said vibrated bed; means for a first employment of said vibration, elevating said withdrawn matter to substantially the elevation of said ceiling; means for a second employment of said vibration, distributing said elevated matter across said ceiling in a direction generally perpendicular to said side walls; an arrangement that permits said distributed matter to fall through said space; means for causing a gas to enter said space across said front wall, to flow horizontally through said space, and to exit said space across said back wall, the said flowing gas having a temperature different from said falling matter and exchanging heat therewith.
