ABSTRACT:
In brief, a grid plate, especially a flat grid plate, horizontally disposed in a fluidized solids contacting vessel, is supported by a conical skirt that extends downwardly and inwardly from substantially the outer periphery of the grid plate for a predetermined portion of the length of the skirt and then downwardly to the bottom of the vessel. Preferably, the conical skirt extends inwardly at an angle, .alpha., measured from the vertical in the range of about 20 degrees to about 45 degrees, and preferably about 30 degrees, for a distance equal to about one third to one half of the length of the skirt, and generally for a distance of about half the length of the skirt.
