Abstract: A fitment for use with a flexible container having a lower fitment member with a fluid conducting opening in a top surface and an upper fitment member with an upper fitment opening in an upper fitment bottom surface where the fluid conducting opening and the upper fitment opening form a fluid passageway or conduit. A wall of the flexible container is compressibly held between the top surface of the lower fitment member and the upper fitment bottom surface. The fitment may also include one or more additional walls of one or more additional flexible containers forming a bag-in-a-bag structure.

Abstract: A supersonic coal water slurry atomizer utilizing supersonic gas velocities to atomize coal water slurry is provided wherein atomization occurs externally of the atomizer. The atomizer has a central tube defining a coal water slurry passageway surrounded by an annular sleeve defining an annular passageway for gas. A converging/diverging section is provided for accelerating gas in the annular passageway to supersonic velocities.
