Westbrook, A S

An overview of dense-phase (non-fluidized) pneumatic conveyings of coal and ash is presented. Today, there are over 200 dense-phase coal and ash handling systems in land-based boiler plants. In this system, the volume ratio of air-to-material is 25: 1 or less. The velocities normally range from 5 to 7 in/s for coal and 6 to 7 m/s for boiler ash. A comparison is made with lean-phase (fluidized) and medium-phase (semi-fluidized) conveying. The conveying sequences, maintenance benefits, storage, shipboard applications, and various power plant applications are explained, and illustrated with diagrams.
