Abstract

The charging trends of particulate materials in gas–solid flows in pipelines are of
considerable interest to designers of such flowsystems, particularly with regard to flow
instruments based on electrostatic measurement principles. Such data may also be useful to
other researchers in associated fields. The authors of this paper, therefore, set about obtaining
such data empirically. In order to achieve this, a small-scale test rig was designed
incorporating a 26.5mm bore pipeline, particulate material feeder, and electric charge
measurement equipment. Charging trends are reported for flowvelocities in the range
16–36 m/s and particle concentrations in the range 5–50 mg/m3. Aluminium hydroxide,
aluminium oxide, sugar and pulverised coal samples graded to have particle sizes in the range
90–106 mm were tested. Samples of aluminium hydroxide graded to between 45–53 and
63–75 mm were also tested
