摘要： A method for the dense-phase flow of particulate solids utilizes a pressurized feeder and flow splitter which transports and equally divides particulate material at essentially the bulk density with only the gas contained in interstices of the solid particles being used to transport the particles. The feeder comprises a vessel which is pressurized, a gas source for pressurization and an outlet line with a full opening valve located immediately adjacent to the feeder. The loaded vessel containing particulate matter is pressurized, followed by opening the valve adjacent the feeder, the valve and relatively empty downstream line when flow is initiated being the key to successful operation of the dense-phase feeder. The downstream flow divider evenly distributes the dense-phase material to, for example, a multiplicity of feed passages in a multi-passage injector.
