ABSTRACT:
Methods of conveying solid particles via an elongate tube from a supplying region at one pressure to a receiving region at a substantially different pressure. Movable sealing zones, comprising mixtures of solid particles and liquid, contact the inner wall of the tube and are carried along with the particles when forced by a ram from the tube into the receiving region. While the particles and sealing zones are being conveyed into the tube, a gate or an auger at the receiving region may substantially seal it from the tube. Typically the sealing zones are formed as thin disks or annular layers of fine coal particles and oil, where discrete coal charges are fed into a gasifier unit.
