  • Method for determining sticking and flow properties of particulate solids
    Patent number: 7615098
    Abstract: A method of obtaining a measure of the stickiness of heated particulate solids (40) includes pouring a sample of the particulate solids (40) onto a generally horizontal support (12) and allowing it to freely form its own angle of repose. The sample is subjected to a predetermined heat and gas atmosphere regime, and the support is rotated about a generally horizontal axis to an angle (42) where the integrity of the sample (40) fails. The angular position (42) is a measure of the stickness of the particulate solid (40).
    Type: Grant

  • Flow field in the inlet plenum of a fluidized bed
    Patent number: 6299826
    Abstract: A gas plenum assembly for a fluidised bed apparatus, including a structure defining one or more side and base walls about a plenum chamber and means defining an inlet for gas to the chamber, arranged so that the gas flows generally upwardly into the chamber from the inlet. The assembly includes distributor means overlying the chamber, having multiple openings through which the gas exits the chamber for forming a fluidised bed above the distributor means. Means are disposed between the inlet and the distributor means for spreading the gas flow among the openings. The gas flow spreader means has a plurality of apertures for the gas flow therethrough, and the gas flow spreader means and the flow apertures are sized and arranged to substantially reduce cross-flow velocity of the gas at the openings.
