Abstract
The invention is directed to a method and apparatus for establishing and maintaining a uniform mass flow rate of particulate solids and gas mixture from a container to a receiving reactor. A preferred embodiment utilizes an aeration tube suspended in the particulate mixture and serving as a fluidic valve to maintain a uniform mass flow rate. A portion of the aeration gaseous fluid may be directed upward in aid of such flow.
